My 2015 GMC Sierra quit blowing cold air today after 97,000 miles.  Compressor cycles fine, but there’s now a low hissing sound coming from the air ducts.  I would assume the condenser finally went.  For those of you who have had yours replaced:

 

What’s the your cost been to replace?  (I won’t be tackling this one myself)

 

I know this has been a common/hot button issue for these trucks, is it worth trying to get GM involved to cover part of the cost?  I’m sure it’s a stretch now that mines 7+ years old.

They won't cover it at this point, not even worth it to try.

 

If I had to guess at the cost with current labor rates it's probably $500-600. A GM part is going to be ~$200 and labor in that 200-300, add tax and fees.

 

Smaller shops will be cheaper and so with aftermarket parts. I've always gone aftermarket because of cost and never had a failure.

I would double check the joint between the sides of the condenser and the fins. Mine broke at 65k miles and I replaced it myself with a new condenser from Napa. It seems a whole lot better for quality than the OEM GM one (same for the radiator I just had replaced a few months ago too). It's been 3 years now on my new condenser and it's been working great.

 

The price cost me about as much as taking it into the shop for work since I had decided to buy a vacuum pump from harbor freight and a set of manifold gauges from there too along with the cost of the PAG oil, a little top off of the transmission fluid and the cans of R134a to refill the system. It already leaked out totally before I started my work so there was no recovery needed as it all bled out from the crack in the condenser.

 

For parts, this is what I bought:

 

- A new rubber gasket for the seal between the condenser and lineset on the passenger side

- new condenser (obviously)

- PAG oil

- cans of R134a (I think I used almost 3 of the small little cans

- an adapter for tapping/piercing the R134a cans to allow refilling the system through the manifold gauge service port

- manifold gauge from harbor freight

- vacuum pump from harbor freight

- a small bottle of Dexron VI to top off the trans fluid

- jiffy tite removal kit since using a pick on the quick disconnects will loosen up the clip and I don't like doing that plus I use the crap out of the kit now on other vehicles in the family.

i picked a replacement from Rock Auto, somewhere around $200.  Fortunately, my friend is a skilled HVAC mechanic and we able to replace it in a few hours.  Following the replacement, the additional costs were 1 can of freon, 1 qt of transmission fluid,  lunch, a few beers and tequila shots.

I had mine replaced at a small AC shop. 
owner said he had replaced many on the GMC & Sierras. 
I paid $250 for parts & $250 for labor- 

thats half what the dealer wanted. 
 

good luck

      The engine was done as part of the 6.2 recall?   You'd have to see if your VIN also has the 6.2 engine special coverage on it.  Coverage number is N252494003.  If you have this, your engine is covered under this and NOT the GM replacement part engine warranty which is 3yr/100k from the date of install.  The 3yr/100k mi warranty is in effect for non warranty purchases.     This is not any different if it was replaced under warranty without a recall or special coverage.  So if you had a 5.3 and it popped at 3 years in at 50,000mi during the 5yr/60k powertrain, the replacement engine would not get the 3yr/100k, and instead gets the remainder of the 5yr/60k as coverage.     So N252494003 gives 10 years or 150,000mi of coverage, which ever comes first, starting at the vehicle in service date.  So if your in service date is 01/01/2022, N252494003 gives you special coverage of the engine until 01/01/2032 or 150,000mi, whichever comes first.  So if your start date was 01/01/2022, you'd have left 5 years and 4 months (lets round to august 1st), or 62,000mi left of coverage.   So you need to know your in service date to know how much coverage is left.

      Injector update

      By CamGTP · Posted

      Okiee dokie there bud, way to take things to the extreme.   I guess you missed the whole point and take things way to serious. I installed different EV6 style injectors that just so happen to be larger in my car running the same LQ4 engine and with a better spray pattern than the stock style injectors and I noticed no difference in the idle quality. Kinda was my round about way of saying that even if you put the same size but better style injectors in your truck, you will likely see the same thing.    I'm sure you're great to have conversations with in person if that's how you act through a keyboard. One little things sets you off and now I guess my dick is all up in your face.

      I can't believe that could possibly be the case. It should be 36mo/100k miles from installation. Then again, it also seems like since a dealership installed it, it'd all be in the system and you wouldn't need to worry about registering, either. Shows you what I know. 😄 Hope this one outlives the warranty!

      I haven't seen inventory recovery from COVID.    In the few random times I 'build my own' truck or SUV, no one has the exact one I want.   GM has been working to lower incentives too for a long time.    A $500 incentive isn't getting me off the couch to go truck shopping.
