'19 3500 L5P (black/black)  Over 100 today and AC isn't working.  My guess is the climate control computer got really hot and that caused it.  Was in direct sun for about 3 hours.  After leaving in shade at home, it's now working.  Pretty lame.  Anyone have this issue? Is there a fix?  Hate to waste a day at the dealer just to be told is a-okay.  (Compressor clutch wasn't engaging, by the way.  Ice cold now that it's working again). Thanks.

I'm in hot humid Louisiana and must say my a/c works great and haven't had a problem all summer.  100° temps with 115° heat index and blows 38° out the vents.  Hope your a/c isn't on the brink of going out like another members here did.  The whole interior, dash, seats had to come out to change a leaking evaporator.  Not a pretty sight...

Here's (from a member Bill) what an interior of a '19 looks like when changing an evaporator...

Yep... I never followed up with him to see how the outcome was.

I imagine it's a computer board that just can't handle the heat.  Worked fine once I parked in the shade after a couple hours.  Works fine this AM as well.  My guess is they won't be able to diagnose the problem this season.  Guess I better turn that appointment into an oil change as well so I don't completely waste my time.

Took it in.  Freon was low.  No leak detected.  Dye added in hopes of finding the leak.  Still not sure that was the cause as it only failed on a 100 degree day, but perhaps.  Unfortunately, no more 100 degrees this year. Got my heater plug cut off and an unexpected bonus :-(

If the evaporator has a tiny leak I don't think the dye will show due to it's location. I hope it's not the evaporator.

Mine goes in for the second time next week for weak AC on the drivers side.  Last time it was 0.2kg low on Freon.  Worked fine for a month, now it's failing again.  I suspect there's a leak even though they pressure tested it.  They said they should have put dye in last time, so hopefully they can see the leak this time.  If not it'll be a recharge and dye, and wait for it to fail again.

It's not the sun overheating anything, its cheap rubbish made parts. Go look at the 14-18 forums to see what great pieces of crap gm a/c parts consist of these days. Mine lasted 3 1/2 years at least, and 32k before it decided to leak from oh the lines, the evap, the condenser, only original piece left now is the compressor and i heard those are not much better. Looks like they are using the same low quality components that are guaranteed to fail at some point.

Sounds like I have the same issue as some of you.  Driver side air conditioning is not cold.  Took it in with 1200 miles - refrigerant was low.  Service re-charged refrigerant and put in green dye.  Same issue came back 3 weeks later.  Refrigerant was 50%.  Clearly a leak but they cannot detect the leak.  They are saying they may have to replace/repair the evaporator (which is a pretty invasive fix).  Possibly the condenser.  

 

Has anyone had this issue resolved?  What was the solution in your case?

I'm having the same issue now on my 2019 Silverado. Air cold on passenger side,  hot on drivers side with temps set at same level. Will be taking it in this week to check it out.

I will now be on my 5th attempt at fixing it later today.  Anyone ever get a resolution on the drivers side no AC?  I've had 3 recharges, and 1 damper accuator replacement.  No luck still, and no sign of the dye from the leak.  I have a feeling my truck will soon look like truck pictured above.

      OCI, not when but why?

      My post above is the direct reason for my outsized interest in keeping what I have for as long as possible. My memory isn't as short as some.

      I don't think so. 😏 Cars? Our experience will diverge there as well. I was buying cars with 200K (1970's) when I started and quite a few were pretty solid cars. (My early stuff was 1964 to 1968)  Some stinkers but not the dismal picture painted above. Now that said, yes, a dealer wouldn't talk to you if your car had more than 60K on the clock and lot cars were 60K or less except the back row where 100-120K was the auction bought for dirt for us poor losers. Kids in my county were not allowed to wear long pants if they couldn't rebuild and repair every part of that beast.    I will agree that many parts are now better. Alternators and charging systems are an envy. But I replaced few water pumps or power steering pumps then. Rebuilt carburetors but replaced few. Mufflers are another place of OEM improvement. Stainless? We didn't have no stink'n stainless.    As long as humans are in charge of governance this $$$$ situation will not improve.    The purchasing power of a dollar in 1955 is significantly higher than in 2025, meaning that a dollar could buy more goods and services in 1955 compared to 2025 due to inflation over the years. For example, what you could buy for $1 in 1955 would require approximately $10.50 in 2025.  Calculator.net inflationtool.com   Comparison of Purchasing Power: 1955 vs 2025 The purchasing power of a dollar has changed significantly from 1955 to 2025 due to inflation. Below is a breakdown of how much more money is needed in 2025 to match the buying power of a dollar in 1955. Purchasing Power Overview Year Equivalent Value of $1 in 1955 1955 $1.00 2025 $10.50 Key Points Inflation Impact: The value of money decreases over time due to inflation, meaning that the same amount of money buys fewer goods and services in the future. Example of Inflation: What could be purchased for $1 in 1955 would require approximately $10.50 in 2025. This illustrates how inflation has eroded the purchasing power of the dollar over the decades. Understanding these changes in purchasing power is crucial for financial planning and assessing economic conditions over time.  Wikipedia Calculator.net

      The thermometer has been in my wife's 2008 envoy, my sons 2016 chevy, my friends 2020 1500 silverado all showing cooler readings. It's not the guage.

      Trim level custom/pro

      By Gary Doolin · Posted

      Have a question concerning trim levels. Ive not bought a new vehicle since 2006, and I have decided on a 2500 gmc pro or silverado custom. For anyone that has one of these 2 trim levels have you regretted not stepping up to the LT or SLE. I look at things as the more electronics the more problems to arise. I love the look of the old school gauges on the dash as well. Looking forward to hearing your thoughts.

      If that guage has a way to adjust [hex on bottom], put that thing in a glass full of ice, put water in, put your gage in, let it sit for 3 minutes or so, and set it to 33 degrees.
