Chevy/GMC Truck: A/C Stopped Working

[@mattdykhouse]

Morning Eric :) - Don't know if it's my end or not but there is a video glitch throughout (pixels all over).

[@gpadog]

Its on youtube's end.

[@chrisschultz6541]

Same here. Is Eric O part of the matrix?

[@basecom70]

Same here. Some views are pixelated....

[@kurtgrates4964]

Same her

[@staind288]

Yep definitely pixelating

[@gungadinn]

Two ways this could have gone. Customer brings truck to South Main Auto Rapair, Eric O spends 30 minutes trouble shooting the system, identifies a chaffed wire, effects repair, and while truck is in, checks charge level of the AC. Customer gets a call, the truck is ready for pickup. Customer is elated that it's done and has many additional years of vehicle service. Owner takes truck to Stealership. They keep the truck for 3 weeks, then declare the truck needs a wiring harness @ $2500 installed, but will take 2 additional weeks to install. Second option, they offer the customer $1900 trade-in for the truck if he purchases another Silverado HD2500 or HD3500 with the Duramax. We know how this one turned out. Customer is a happy guy and South Main Auto has a happy customer.

[@drucifer_too]

Third way - customer continues to sweat until labor day then doesn't really need AC.

[@Donnybrook10]

option 3...mechanic says you need a new compressor. $600 later, problem will present.

[@eizzle78]

Donnybrook that’s what I was thinking. Then it’s a new pcm, then it’s a new truck.

[@Peter-pv8xx]

My neighbors 2014 Kia soul with 25,000, Midas or some other rip off place told her she needed new front bake pads front end work and an alignment,so ahe asked me to check it out, brake pads yes so I did them, front end work and an alignment, no, the front end is like brand new its tight as a drum, 25,000 miles, she just drives local, some places see a woman and dollar signs flash before their eyes.

Let me guess he knows more than the people who engineered it. This is not rocket science you make this out to be something where 1 person in some liberal state can do.

[@catmshtr89]

A Sunday morning video by Eric O? A welcome surprise. Sometimes it's good to be lucky.

[@scottfirman]

You are truly a master at electrical wiring repair. Your method of deduction actually saves time and is easier than throwing stupid at it like I see other mechanics do. Using the process of elimination is less costly than assuming that the freon was low or the low pressure switch was bad. I have seen mechanics waste money on buying parts that didnt need replacing, then after finding the real issue, still hitting the owner up for their mistakes.

[@noelhernandez5016]

[@williampaap2098]

Love your , how should I say this, your tutorials. I also like your saying- " If I can do it, you can do it".... For me, That might have been true 40 years ago. Just can't move and bend like I did in the old days..... The last work I did on a vehicle was my wife's 2000 blazer. Replaced the radiator and the fuel filter. The radiator was easy, but the fuel filter got me. I swear there was enough room between the torsion bar and frame, and the should have been, but my fingers could no longer make the bends. The torsion bar needed to be further in.... Really pissed me off.. Max frustration.. On a second note, you're spoiled! If I asked my wife what's for lunch, her response would be, " So what are going to get or what are you making"..... You are truly a gifted young man.

[@BigDaddy_MRI]

Logical troubleshooting rules. Procedural step-by-step tracking of “how it should work”. And discovery of why it isn’t working. The way you collapse diagnosis steps is simply perfect for teaching. Power? Grounds? Command signal? No command. How many connectors in this wire chain? None? Ok. Let’s find problem with this wire. This reminds me how the Navy taught us how to find broken wires in wire looms in the A7-E Attack aircraft. You Mr. O, are a steely eyed missile man. Thanks for the great video!!

[@morrisontimothy227]

I love how you go into depth of the troubleshooting process. However you know when dealing with an inop ac compressor the first thing 90% of us do is swap the relay with known good. Lol. Great work though. Love it

[@CubasAutomotive]

Yeah, the video was glitchy, but totally watchable! Got all the important parts in! You really did get lucky having that wire break out in the open, just about. Wasn't in the easiest get to spot, but could've definitely been worse! Now all you have to do is get rid of that SD card... lol 😉😉😊🤗

[@wirenutt57]

As an industrial electrician, finding that broken wire was the satisfying eureka moment. Since I also deal with invisible angry pixies in my job, it's rarely visually obvious when something is broken, but I enjoy finding obvious problems like this. Industrial mechanics have it easy, they can almost always see what's wrong, for example a bunch of ball bearings bouncing off the concrete or a belt that doesn't seem to loop around and connect to itself like it's supposed to. When you pulled that thread of insulation apart, I laughed it up pretty good here, especially since you had already questioned the integrity of that exact wire.

@@jaredstrehlein5605 Think he was just pointing out the actual repair was trivial, but knowing what to repair is the hard part.

My first go-to in such a situation is visual inspection of the wiring. Even if you didn't know which wire went to the relay from the pcm you went directly to a bad wire when you did the visual.

[@dtnel]

Years ago they made a kit as Joe said plus there was a flushing solution you had to use as part of the process. Better do it sooner as the new refrigerant that's been out, the 1234xy whatever will undoubtedly drive the price of R134 refrigerant up and the further it goes the higher it'll go and the newer refrigerant isn't much cheaper either and won't ever be from the way things are looking either........
