    I grew up on GM vehicles but they've never been that reliable. However I will say despite their problems, back in the day nobody made a better air conditioning system. Apparently those days are over. My family gave up on GM when my Mom's 3 day old '96 Olds broke down on her, stayed in the shop 2 months and GM finally bought it back. Replaced it with a Honda Accord and never looked back. My Dad bought a '96 Ford Ranger shortly after that fiasco and it's still running

    Listen to how nice and quiet the shop is today, No blaring radio.

    Why would this Sierra be at the Dealership for warranty work. It is definitely still under warranty, is the Dealer a real jerk??? Can you do warranty work and bill GMC?

    The dreaded GM junk condenser premature failure

  6. Avataaar/Circle Created with python_avatars blxtothis says:

    Don’t think the temp dropped below 66°F, was hovering between thereabouts despite the cockpit instrument display reading 71°,

    Should be under warrente.

  8. Avataaar/Circle Created with python_avatars Bowhunters says:

    Too much refrigerant is probably just as bad as too little as it probably messes with the systems operation from condenser to heat exchanger?

    All Suburbans or Yukon Denalis, we've had 1988, 1994, 2005, and (since May 2021) a 2011 Yukon Denali, in Arizona desert. ALL had AC that got a lot cooler even in our summers than the vehicle Ray had here. Maybe just another example of "cost savings" by manufacturer that backfired.

  10. Avataaar/Circle Created with python_avatars Kenneth Oakes says:

    Hey Ray, you were on the right track with the temp. sensor on that F150 but gave up and ripped the whole dash off. Why didn’t you go to a scrapyard to source a sensor first?

    Ray keeps his Therm-O-Meter in a special, heated toolbox drawer.

    Ahh the fake Allison pickup 😂😂

    What about warrenty coverage

    This guy is still using windows 7. Lucky.

  15. Avataaar/Circle Created with python_avatars 0cypher0 says:

    You can say what you want about European cars, but in my experience the AC service connectors are mostly pretty easily accessible in those. Or at least that's the case in the models not intended for export to the US. 😝

    We are in spec, the customer must have loved hearing that.

    My 2018 Subaru Outback 2.5 L can generate 40+ degrees on a 90+ degree hot day. But it has to be on recirculate.

  18. Avataaar/Circle Created with python_avatars Nick Malone says:

    I dont understand why you are getting GM warranty work…explain

  19. Avataaar/Circle Created with python_avatars Matt Wilkerson says:

    Blower set to high speed will not produce the lowest air temperature. The higher air velocity will reduce the amount of time the air is in contact with the evaporator, and increase the output temperature.

  20. Avataaar/Circle Created with python_avatars G_Block says:

    I grew up on GM. I worked for GM. I love GM. But they can be such crap vehicles.

  21. Avataaar/Circle Created with python_avatars johnnypk1963 says:

    Should’nt the truck still be under warranty?!

  22. Avataaar/Circle Created with python_avatars chris55130 says:

    Weak compressor or expansion valve isn't working correctly. If they are, the air blend door/ recirculate damper could be stuck allowing heat in the duct work when not called for..

  23. Avataaar/Circle Created with python_avatars Mark Simonds says:

    Thank you Ray for posting all these repair videos… very informative – but most importantly – lets me know what vehicles NOT to buy!!

  24. Avataaar/Circle Created with python_avatars WST says:

    Have u come across the Ford Escape a 2013 and newer issue of AC blowing warm air after system has been running for a while?
    There is a TSB on this

    Nice job and video like always

  27. Avataaar/Circle Created with python_avatars YaGotWrektM8 says:

    Ray your videos are the best auto repair related ones on YouTube. Your camera work is outstanding! You are an outstanding mechanic totally subscribed thank you.

  28. Avataaar/Circle Created with python_avatars Chris Howell says:

    But it was that GM Mexican refrigerant so you need to use more to get the same effect.

    GM….

    You should have checked the charge wt in the second vehicle with the customer's vehicle. Could be a scale deviation or error.

    I was assigned a wirk truck once and if you turned on the ac the cab quickly became the same temp as the engine it was horrible, boss refused to fix it to

  32. Avataaar/Circle Created with python_avatars ShadowJacker says:

    I really like this channel lol. Keep posting content man!

  33. Avataaar/Circle Created with python_avatars Mike H says:

    Yep, R134 will actually blow warm if overcharged. If GM had gone with a TXV using a cap tube sensor, the overcharge would not have made any difference.

  34. Avataaar/Circle Created with python_avatars Vidyanand Mohabir says:

    im amazed how these new trucks got so many problems.

  35. Avataaar/Circle Created with python_avatars ianriggs says:

    Having A/C problems in a 2020 Savana work van in our company. It the compressor just cycles on a hot start. Clicks on, clicks off, clicks on, clicks off. So naturally the air gets cool, then hot etc as the compressor cycles. Once the vehicle has been running a bit or You actually start driving it, the ac works fine. Any ideas? Very hard to leave it at the dealership while they try to figure it out

  36. Avataaar/Circle Created with python_avatars 123698783 says:

    Clutch fan is weak. Fan not running right rpms at idle or low speeds.

  37. Avataaar/Circle Created with python_avatars SICKS6SIX says:

    one day someone will make an A/C system that works properly and never leaks or need refilling like a household fridge which you can buy for £100/$120 . . . .

  38. Avataaar/Circle Created with python_avatars Tim Jones says:

    do these have electric compressors or belt drives

  39. Avataaar/Circle Created with python_avatars D Snicker says:

    I got so tired of watching him futs with that temperature gauge that I turned the damn thing off.

  40. Avataaar/Circle Created with python_avatars FatManChew909 says:

    My 10 year old 4 cylinderToyota Venza can reach mid 40's. GM can't go below mid 50's is pretty bad.
