Hey there, viewers welcome back to the self-made knowledge channel, that's a 2007 chevrolet 1500. It's got the big five three, the money lights on uh. The guy uh told me that he's having problems with the cooling fans, or at least that's a coat. It's throwing - and i think i've had past experiences with these chevrolets and they tend to rot out the harness on the bottom of the coolant fan relays.

If i remember right, because i think you have to pull the whole top off the fuse box just kind of going off memory, but it kind of sticks with me that mice like to get in there, you know, obviously, in this style fuse box - needs gm for Whatever reason they love build little nests there and like say, i've had problems with these trucks. I think in the past uh with those relays kind of crowding off there. However, let's not jump to any conclusions. Let's see what he says is correct.

I let her do a full scan uh, so we've got an evap vent, solenoid circuit, classic uh. It's failed mill requested. That's interesting. These aren't requesting the mill.

But yes, he does have cooling, fan control circuit codes, uh airbag instrument, cluster um. So that's interesting! Okay. I always like to pop in obd2 a little cya. I call it cover your tiny because see here we have three and complete monitor, so this thing could have a host of other codes.

You know because i doubt evaps done or catalyst, let's see here. Just this way here, we've got documentation, so catalyst is incomplete. Evaps incomplete o2 is incomplete, so he could have you know your classic. 420.

430 codes. You know other evap leak codes, o2 code, so anyhow this just gives us some documentation. So when the vehicle comes back with other lights on so yes current current current, so three current codes um, he was, i think he was mostly concerned about these two. This is probably just a bad vent valve, but let's focus on our fans for right now.

Uh we'll get back into oem data, get a diagram see what the deal is so before we get too excited. I'm just gon na go to uh some bi-directional tests here. Just turn the relays on it's got looks like a classic three relay system uh. This turns on one two and three.

I don't hear anything clicking, let that truck go by here. I just want to do it again. Yeah we got nothing folks, uh! I do see, though i don't know if you guys can see her not in that angle, but the command looked like it was being received. So fan control relay one two and three all set on when i turned them on just like that.

So that's something worthy to note. Uh at this point, uh there's no sense going any further. Until we get a diagram, we know what fuses the check and how the system works um and then we'll go right for the gusto. Seeing all the insulation off back here is probably not too far fetched to think about mice got us a diagram here that has the relays on it.

So it looks like we have three fuses: cool fan, cool fan and cool fan uh, so we got ta find the cool fan fuse. This looks like two 40s and a 10. and i'll see if they're up here, where we can get to them or memory, serves me right, everything's under this box. But let me do some poking here and see: yeah see they're off to they're in this little winger off to the side, cool fan, cool fan, cool fan, two 40s and a ten and three relays.

However, it's underneath that so, let's get a 13 mil, get this little brace out of the way there. Now we can see what we came to see any mice smell like mice, there's a lot of dirt and junk down here, but i don't see uh. I don't see piles of insulation, which is good uh. So let's find us a good ground right here on this support right here.

Click on that we've got a light. Oh yeah, like your problem right here, uh. Well, that's uh escalated quickly. The fuse is gone.

It's corroded off, and this is nothing but a big pile of blue puss. Let's have a gander of these. These bigger uh, 40 amp fuses. They look good looking at them from the top here see if we have any power coming up to them.

That's unusual. We have no power that stud has no power. That's quite interesting here, folks. I would assume that one half of these would have power because they are supposed to be hot at all times, so that's kind of weird that neither either side of those has power on it.

Let's see where that power source comes from, i mean. Obviously, this 10 ampere being gone is an issue, but i wonder why these 40 amperes here have nothing. This whole thing, uh wonder how that whole thing comes out, but let me uh, let me backtrack this power feed a little bit here. It says uh, according to the diagram.

There's a black wire supposedly feeds it right directly from the battery. We got to get this uh connector here out. Oh boy holy smokes, this ain't good. This is really bad uh.

It doesn't have any power because there's no bus bar left, that's angry. Looking yeah, we have power there, but okay, we have power there yeah. Let's say this: thing's nothing but plus this bus bar is corroded right in half somewhere through this area still has power there but start disappearing there. Pretty quick, fella uh, that's a waste of time here.

Folks, i don't see any mice here. Um, pull it right up here where we can get to it. Look at that! That's a mess! This wire is broke, there's a random. I start touching stuff, but uh.

This wire here is busted, so the other half of that fuse. Now that's part of a relay. Wherever that fuse went, the fuse went over there. That's nothing, but pus wait.

That's some stuff! I suppose what we can do so here's our fuse. So that's all that was left with our fuse. We can go to uh wilbert's, you pull a bath, they don't sponsor us, we can cross our fingers, we can knock on something we can get good vibes and hopefully find one of these. I don't know.

I don't know how many years this thing fits, but i say we go look for this baby, not a lot of wires, but the problem is in our climate. I don't know, i don't know if we're gon na find what we need or not. Let's go have a little look-see, because if not we're gon na have to come up with plan b, see you later lady yeah go out and do some sick things in the jeep. Good luck don't get stuck.

I won't get stuck. You see me with the tundra. This weekend, right, yeah, pretty impressive right. I was like.

Oh man, don't get stuck. Why are you walking i'll blow that freaking engine right out of the hood before we walk? You have to go borrow a farmer's tractor, nope nope. We got out yeah all right, see, ya, yeah me and miss almost got stuck this week almost, but i showed her roll that window up. I showed her what rev limiters are for uh.

I was a little nervous. We was a long ways back in the bush. As they say, and we were buried, however, the tundra came through put the pedal right to the plastic, no mercy, reverse, you should have had the camera going, you guys would have loved it, and here we are folks we'll walk down the long row chevrolet's like that. Three of them, i think it should be easy to identify, because it should be just the box that has the extra donger on it boom.

This one's got i'll, be jiggered the first one. I guess the only thing is, though we could be, could be in the same shape we're into the shop as far as the rust in the crust. We don't know, let me set you down folks, i didn't bring my tripod. I always feel like a ding-dong when i walk in like that.

What do you got the camera for then you got to explain to him push on that. Give that a flick up. She comes oh baby. I don't think it's as bad.

It ain't great. It ain't. Great but it ain't bad heck of a lot better than where we're at so what we'll do i think, we'll we'll keep on searching? We will it's really not terrible. Let me pull out some relays here, yeah.

It might be worse than i think, though, yeah this one's pretty crappy too crap cola, this one's crappy and ours is crappy. I bet the other ones are going to be crappy negative, ghost rider. So oh there's a mouse under here the holy grail, hallelujah. Look at look at that thing.

It must be from florida. Hey look at this thing clean as a whistle good deal, so i just chopped it off uh one two three and then six seven, eight eight wires we're to do the old spliceroo, because that's going to be the easiest thing to do and then we'll douse that, With some fluid film and send the fell on his way, all right folks success, i paid in full one dollar and 85 cents that cost us 1.85 we'll mark it up. 7 000 percent ish a dollar dollar 85. How can you go wrong? How can you go wrong at wilbert's, you pull in a bath, you can folks, you can't freaking love this place.

The only thing that sucks is so they clean out all the cars, so it kind of takes the fun out of it a little bit like they take out all the loose change drug paraphenalia books. You know the things that people have in their car when they crash or when they donate them. So that's kind of i always kind of like treasure hunting, but there's no more treasure hunting other than the part you're. Looking for, i should be ashamed of myself.

Folks walked out of my house today with no knife. Uh we're gon na take whoa whoa whoa whoa whoa lot going on right. There hold on stop there we're going to hook the battery because we need to chop it off and uh. We know what codes were in it, so not a big deal um.

I don't know. If i'm going to bore you with this entire process, the boring bits we're going to take i'll, show you some of it, but it's all going to be kind of the same. In the sense that we're just going to be cutting soldering and heat shrinking the wires over here, i'm going to get the good one here opened up and then we'll open up this one, we'll splice it with about the same amount of wire. So we can kind of run it in the same direction and we'll just click it back over here where it was we'll blow all this junk out, or at least vacuum it out perhaps, and get rid of some of this a lot of corrosion around here and I'm assuming it's all just coming from the bottom of the box, i don't know, i don't know who they missed more.

If it's the dogs or you now i lost my razor blade. Can you believe i walked out of the house today. We're doing nice kind of like going to the store yesterday with no wallet what an idiot at least your fly was up yeah. Is that an older person problem? I tell you folks, i'm going to be pretty transparent here, i'm having this issue where now so i did that video a while back.

You guys didn't get to see it on the 71 dodge pickup put in the upper control arm bushings. I get to see it because my fly was down the entire video not like everything was hanging out it pretty much almost was no anyhow, i didn't show it because it was embarrassing and it was a great video too and a lot of fun in it, and I didn't end up showing it threw away the footage, so don't ask for it. Don't have it no more, but anyhow, i don't know if that's something that happens, the guys when they get older just all of a sudden, their flies are always open. I don't know how this happened, but it is how i've discovered that i was missing my wallet yesterday at the grocery store yeah.

I was checking my flag because i'm checking all the time because, like three times now, i've been like all of a sudden there. It is my ding dong's getting drafty and i'm like. What's going, how did i leave my fly? Open i've never had this problem. 42 years old, all of a sudden 42nd birthday, ding dong's hanging out all the time like what happened.

What part of my process do? I skip now apparently they're putting the knife in the pocket part that too you got your wallet today. I do maybe buy them so we're doing good two out of three ain't: bad! That's right! Anyways your nails, yeah uh they're, like all bending over on your little license plate deal. Oh yes, you got a trick for me. I got all kinds of tricks to keep my nails from bending over yeah.

This is always putting up a license plate. She went through all of our license plate collection yesterday and she she sorted everything out. Um. Do you know what like 200 and oh, that's, probably more than that? It's probably like about 300 license plates.

We still don't have all 50 states how many are lacking 18. So i decided to go with your classic crimp and seal connector uh. It makes a good mechanical connection, heat shrinks it and oozes out the glue. I have no reason not to uh so pretty standard stuff.

You guys have seen me do this a lot. You know in wire repairs uh. However, i am down to the situation, got a little bit of a situation over here um and that situation is. We got two wires that are the same color, so we have two of these dark blue wires.

That are the same gauge uh wire and they both go to one part of a relay. So i decided i better pull up a diagram to see if they're, different and they're not so both of them go to uh what appears to be pin 86. So i think that is, that's got to be uh, that's a control side for relay two and three um and they splice together here down the line so uh somewhere is down. The line here is place 166 uh they come together, so we can hook them to either either one of these it doesn't matter, and that's that's all i wanted to look up to be sure was that there, so i would have showed you more of this process.

However, i had a fella come in on us coming in the back door and he's a chatterbox and he's just now, leaving because i had to politely ask him to leave polite. We always ask plate the first time. Ah, let's see here so we'll get that in there get her all lined up crimp it till your knuckles crack we'll do the same on this one old uh, not old, newer exit sign covering up the battery, give us a little spot to work here not to Blow flames directly onto it, stick that one on there and we'll crimp that up here, like so set that down there a torch. Now, if you want to do a really nice job, you would offset all of these splices, so they're not all stacked.

On top of each other, when you tape it up, however, when i looked underneath the truck i'm near certain, it doesn't have probably a year left in it. So i'm not super concerned with how my repair looks as long as it functions well, uh, which it will so i'm going to let these cool down and then we're going to put it back in the harness we're going to tape it back up swing it back Around, of course, all this is going to be underneath the box here, where nobody can see it right, we're close to it. It doesn't really matter in this sense: it's not a lot of wire, so it's not going to be that thick and then we're going to spray the heck out of this with the fluid film we'll take these relays out one at a time we'll spritz them down. Try to keep this from happening, so you can get the rest of the life out of this thing and then like say, we'll get the blow down we'll blast all this junk out of here well just coming out and give you guys a closer look at that.

Just in case, nobody seen it there from the distance, but that's what we were dealing with. What a mess huh probably ought to play it smart and uh. Before we get super deep into taping it up and take care of everything we should turn the key on. After we reconnect the battery make sure it works.

What's up missus, though just wondering what you want to eat eat the lunch. Are you gon na eat? If i warm it up now or you eat now, or do you want to wait a little bit, i'm good? I can eat whatever, okay, whatever is convenient for you and be ready in two minutes. Two minutes. Oh you want me eating two minutes huh i was: we've got less than a minute to go before lunch is ready.

Let's go back into our scan tool, we'll see. If it's still there, we are we'll go back into the fan relays here now. Technically we should hear some clicking and stuff. That's fan relays, one two and three: let's do two and three and then we'll just do relay one by itself there.

She is low speed. High speed on one high speed on both, i think we got it. Fellas where'd you make. Oh me, hello, salad, with barbecue chicken smoked at home by you with applewood yeah where's.

That was right from the apple tree. I cut it down not a real, strong smoke, though no it wasn't strong, it's pretty yummy, it's still good yeah. I mean it smells smokey in here, but it's not like a like a mesquite or a hickory or a maple that we would use it's good, though it's pretty good, i'm not gon na lie. Oh gosh, damn just smell my coffee, oh man, i'm always in a food coma after lunch.

Oh so tired, we got ta get back at it here, we'll get things turned on. I think we left off uh having taped this up now. I think, prior to flipping it over we're going to get a little fluid film spritz her up, get all this stuff good up with a little peanut butter, so we're going to use some groat ultra seal first name in the vehicle safety system that says corrosion, preventative Sealant, i call it peanut butter. I always thought it looked like peanut butter.

Of course it's really not that dark don't eat it. Uh, i'm just going to take and use a acid brush here and we'll smoosh some down inside of the cavities like only minutes ago. I said we were going to use fluid film, and here we are with something else: either either way we just want to get some electrical grease in here. We want to keep this from getting all corroded and crusty.

This stuff works pretty good. In my opinion, we use a lot of it on you know, light bulbs and trailer plugs and stuff like that. It's quite a heavy grease, although it does kind of ooze out or get oozy when it gets hot. I use it on my winch connectors on my jeep and sometimes there'll be a little puddle of the stuff in the back of the jeep, where the winch is oozes out of the connectors there in the summer heat, but it works pretty good.

I use it on my snowplow connector on the front of the tundra and all kinds of stuff works really well. Okay, we've got a little extra wire from what we initially had so we're going to take and get this clicked in first, so it clicks in there and then we have this connector that went in there and then there's lots of room for the extra wire. So we just kind of loop it down in the fuse box here now you can't really see what i'm doing, but essentially there's a lot of room in the bottom of this fuse box. So we can kind of loop that in there get them clicked back in get that one clicked back in and that's that uh not much else to see here.

Folks, we'll get the big cover here cover up all of our wiring and stuff. I think this will be okay. Now this just clicks over top of this down there. I think i might have missed it in the back, though.

Let me double check that back here, just to be sure nope, it's 100 folks, that's clicked on! That's clicked on everything's! Good there, it's kind of a this is kind of useless. It doesn't only give you access to only, but one relay and two of the fuses other than that. This whole thing has to come off. Um kind of like it might have been an afterthought for gm.

Here you can imagine that it seems like they would have made it more convenient to get to uh. I guess if all else fails and if you're in a state where uh they don't have state inspections, and you don't want to fix that, just go to the junk yard and get a fan shroud and and a mechanical fan. They still use the same water pump. Stuff, it's still threaded, that's that's what they use for years, and then i don't know when they started doing this cooling fan relay system, because this is an 07.

So this is the year that gm switched. So this isn't what they call it. Oh seven chevy classic had to be right around this time. They came up with this body style.

What 2004 the slanted headlight one there? Oh 407.! So okay, let's tighten them up. Well, that's that folks all fixed piece of cake uh! Thankfully, we got the wilbert who pulled a bath close by to our shop and uh. Fortunately, they had a chevrolet there that wasn't completely rotted out in the fuse box area, which is great and i'm able to save this guy. You know a ton of money, uh particularly get a you know, truck like this.

All rotted out, you know it's be prohibitive to you know, buy that part from the dealer buy the whole harness whatever you could always just wire in three separate relays with the wires that are there, which that was my plan b uh. This obviously was the best way to go about that they're. The best fix, i guess uh in my opinion, uh the easiest so uh. That's that now we'll see about the uh cancer vent valve circuit co, which is probably just a bad bent valve pretty common, probably tons of videos on those.

I think we've done several too, so i won't bore you with that uh. What i will don't have a transition comment, section questions comments, concerns put them all down there and just remember viewers. If i can do it, you can do it thanks for watching.
