Originally mine was blowing warm air at about 53K and took it in to get it serviced - that lasted less than an day and started me down the "rabbit-hole"...

I had mine replaced in March on my 2014 Sierra  - it looks totally different from the original one - has some sort of heat shield.

Are there any plans for GM to reimburse anyone for the repairs? 

I got out of there for $700.00 - they stated that the higher cost was due to having to remove part of the front end?

They submitted through some GM Customer Service program that "assists" with these type off issues.......

It was still very painful to the pocket book!

Add me to the troubled condenser list...   About a month ago I was driving to work on a sticky Houston night, about ~75*f or so with probably 80% humidity when I noticed that my A/C was not blowin

Hopefully your ac is working great now?     I don't think I'd join one of these class suits over $1k. GM will settle for a fraction of the class costs and most of that will go to the slimey lawyer

Add me, 2016 Serria Denali 60k no ac, but I moved from Maryland to South Carolina and didnt have the time to get it fixed and we made a few trips now have 67k. I bought used at 53k, had the trans flus

My '18 cooler looks just like that.  I'm assuming yours is still running r134a though where mine has the r1234yf.

There is nothing you can do. I have 91,000 on mine and it was the original unit. Ive read where some were brand new and replaced again after 6 months.. So I think I was lucky.

Mine went with only 2,089 miles on my truck.  I only had my truck a few months.

Well add my wife's 2015 Denali to the list.

I also have a 2018 Silverado. Did gm change the design on this or do I still have the same POS condenser?

Look about 3 posts above this one.

 

GM believes the issue is due to thermal cycling (fatigue crack).  They’ve added a heat shield to the upper drivers side corner of the cooler.  This is actually covering part of the trans cooler area to reduce the temperature fluctuations of the area where the receiver is joined to the condenser.

 

Is this enough to eliminate the problem?  I don’t know, but I’m hoping so as that’s what my 2018 has.

 

You should also note that 2017+ trucks have a different refrigerant in them that is much better for the environment, BUT it costs about 10x as much as the previous refrigerant.

My condenser on my 2015 LTZ went out summer of 2017 I believe it was.  This was about when condensers first started failing as the new and improved version was on National backorder.  I had to wait about two months for  replacement to arrive.  However, truck was under warranty and was provided a loaner while waiting.  Good news I’ve had no issues since.  Just goo cold air.  In fact, checked temp at center vent the other day when temp was above 90.  And was getting about 41 ~ 42 degrees which is about right on spec.  Only car in the fam that does better is wifes 2017 BMW 430i which will putout about 39 degrees.

Wow, you had a loaner for 2 months? Good for you rather than accepting the fact they wouldn't have the part and have your truck with no ac in the summer.

You know, I Read a lot of trash talk about bad/unethical dealers.  But, happy to say that hasn't been my experience.  I’ve been buying from the same dealer for about twenty years.  So, maybe there’s something to building relationships?  Seems to work for me.

For all of you guys who have replaced the condenser yourself, did you install new O-Rings in the AC lines at the bottom passenger side?

Do the new condensers come with them?

I put new ones on. Didnt wanna take a chance on it. New condenser did not come with them. But did come with trans cooler fittings and the stud for the ac lines. The 2 tiny gaskets were $21 my cost at the dealer.

Did you go with an AC Delco/Gm brand Condenser or aftermarket?

I would assume the GM gaskets/O-rings will fit an aftermarket condenser.

I went aftermarket.  O'Reilly Auto Parts. Lifetime Warranty.  Total delivered was $133. It was almost exact fit. The plastics on the side of the condenser didnt fit 100% because the trans cooler fittings were a bit different in length sticking out of the side of the condenser. I just used a razor blade to trim them. Took an extra 2 mins.

Thanks for the info Robert.

Seems there are several replacement options out there. Ranging from about $70 up to a factory GM unit for over $200

Average price for a big box auto parts store is about $140

I agree GM should warranty this much like the failing Radiators due to cycling Thermostat on the earlier '14 and '15 models.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      Declaring victory would upset the demons that possess this Blazer, so I won't. But I did make progress today--after it put up a fight. Always a fight.   I had the day off so I spent the morning cleaning up the shop and I thought I'd get ahead of things by filling the cooling system in prep for the final part I needed to arrive: the driver's side knock sensor. Glug, glug, glug....and then the unmistakable sound of liquid hitting the shop floor. It induces the same chagrin when the sonar and targeting laser temporarily malfunction during a late night bladder evacuation over the toilet with the bathroom light off. D'OH!!! That made a mess...   Oh, hey, that knock sensor I removed? It threads into a wet port. Who knew?! Learn something new every day. Put a pin in that chore, I'll fill it the rest of the way later.   The knock sensor arrived at about 1pm. I threaded it in, connected the wire, filled up the coolant, checked for leaks, and... drumroll.... fingers crossed for a perfect start, excellent timing, model fuel trims, and ...no squeaks... Here goes.....   No, it didn't start. At all. I cranked it a few times and it wasn't sounding good. Furthermore, I heard leaking again. Jesus H Tapdancing Christ, stop leaking all over the dang floor. This time I had accidentally overfilled the coolant reservoir and the churn of the water pump via cranking caused a bit to burp out. Ok, just, breathe... Put the flamethrower down. Dang thing wouldn't burn anyway, leaks too much...   Did you know the rotation of a round crank sensor in a round hole, matters? I do now. Took me about half hour to retrace steps and realize what I had done. Then it started right up.   No squeaks. The squeak was the old balancer.   Once it entered closed loop, fuel trims are dead on, hovering right around zero at idle. No more -30%. I'll credit the injector rebuild on that one.   Timing? I think there's an OBD 1.5 translation error with my Actron scanner. It's anywhere from -20 to -30 at idle, sometimes as high as -40 cruising. Sorry, the engine just isn't running that smoothly at -40 degrees ignition advance. It's just not. It's smooth all through the rev range and has decent power. I'm going to have to trust the seat of my pants on this one.   The new exhaust is very quiet. The old catalytic converter? Not melted, but definitely not healthy. Rains glitter when you turn it on its end...all the precious metal is flaking out. Once the new exhaust system burned in/smoked off a bit, the engine's exhaust smell is normal again. Not that I'd recommend going around huffing car exhaust, but, you know what I mean?   One problem to correct. The new exhaust has the opposite problem of the old spliced up exhaust. It wants to hit the floor where the old one wanted to rest on the cross member. Happy medium, please? Still noodling on that one, need to look at how I can adjust some hangers.   I don't know what's next. On one hand I want to run away from this thing as far and as fast as I can -- there have been a lot of NOT fun moments. On the other, now that it kinda drives nice, maybe drive it around for a little bit?   Shhh... it's not currently dripping oil all over the floor. I can see just a little wet at the bottom of the timing cover where it meets the oil pan seal. It's not dripping multiple drops with every ignition cycle, in fact, after some driving this evening it has yet to even form a drop that could drip off yet. But the weekend is young... I fully expect this could turn into Exxon Valdez by Sunday. Because this Blazer hates me. LOL.

      About that:   Once upon a time in a land far far away lived a car company that was shy about taking your money and wanted to be sure that they gave you more that you asked for so that you'd come back. No really, not a fairytale. 😱   But after the field got thinned out enough to limit the competition it seemed good enough to give you only what you asked for. Fair enough I say but in such a market you have to give something the others are not or they go to the one who does. Gimmicks or glitz. Oh, fins and chrome. Yea, shinny crow like cars. Yum.    Field narrows a bit more and 'brand loyalty' becomes a thing and the minute it does they start thinking to themselves, "Could we make more money if we gave them less than they expect and they will hang in there for brand and comfort with the known?" They gave it a try and da*n, it worked!!    Well, what if we teach them, groom them into believing that less is "Normal" and cut some more corners. Will that work? Oh heck yea!    🤔 I wonder, can we give then WAY less than they expect and make them mad enough to spit nails and STILL get them to pay up? Sure, if we get everyone else to do the same so that the choice is less or nothing at all. How would be do that? Platform sharing.  What a concept, right?  Steal like there is no tomorrow and it's legal too!    Truth is no one is going to give up driving, not for very long. The Gen Z crowd is fine with it and will be as long as someone not Gen Z will haul them around. At some point we all die.    Economic voting only works if you cast a NO vote now and again and enough of them to get dumb and dumber to wise up. Well, that's how I was taught anyway. And it should have worked. Would have worked. But the Bail out!!   Look, you have another choice if  you take that bag off your head. If the dumb it down to some predetermined expectation of how John Q Public will use it the, that is under design it to failure they you use it to a lower stress mode. D'ho!    A 1950 Royal Enfield Bullet 500 will go anywhere a Suzuki Hayabusa will and for just as long. But you will have to treat it for what it is and not for what you wish it was.

      Bridgestone vs Goodyear tires?

      By Vu1can · Posted

      Maybe I was just too unlucky, but I had nothing but bad luck with Bridgestones. Out of 3 sets, they all started losing a lot of air when they got down to about 1/2 tread life, and at that point also wet traction suffered more than it should have. Also, the only tire I ever had in my 60 years of driving that had a side wall blow out was a Bridgestone.   I'm currently running Goodyear Wrangler Workhorse AT and am very happy with them.

      maybe when the trip is over, check all the other joints in the front end, like all the ball joints, tie rods, pitman & idler arms, etc...

      adding 360 surround view, UVI (Trailer Camera) package to UVS (Surround/invisible Trailer) Upgrade 2020 Silverado RST

      By Carlos Eduardo Silva · Posted

      Thks, and actually it was my bad, because here in this post there is someone showing the correct wire position as well. My bad... But thank you a lot with the help as well. I was able to find and buy a 10 channel VPM that came from a sister silverado of mine. The same year, same mode, same trim, same everything. 2022 Silverado 1500 LTD LTZ (pre-refresh). I also found to buy just the bottom mirror part that has the cameras, so way cheap than the full mirror. + a used front camera. I did test everything together, cameras, cables and the VPM.... everything worked EXCEPT my original Bed camera and the backup grid lines. I think the reason is because now I need to do the VPM reprogram. I sent a msg White Automotive & Media Service to confirm that it is the problem and that they can do it service for me case.   Once I get it 100% done I will post here result....
