Hello everyone I'm in Arizona, and it's been very hot the last week. My a/c doesn't work well until I'm driving on the highway where air can circulate over the condenser. Around town the a/c air varies from sort of cool to warm even with the recirculation activated. According to the dealer this is a common problem with the new R1234yf refrigerant. For those of you who watch Scotty Kilmer, he just published a YouTube video about how crappy it is. Not only that R1234yf is highly combustable. Can you say engine fires?
Hello I'm having trouble with the A/C in my 2017 Denali. I've already had the condenser replaced last year. I just took a trip to AZ, and A/C would not put out cold air while on auto at 72 degrees. When starting the car on a hot day, the A/C fan would not blow full blast. In fact, I received a phone call and the fan didn't have to slow down like it normally does on a a hot day. During the drive back to CA, the air started working better. The dealer says the system is full of freon and can't recreate the problem. They called GM HQ and was not able to get help from them. Do you have any ideas? Thanks Jerry
I'm glad to hear the 10 speed works well. I'm NOT happy with my 8 speed. Often after slowing down to make a sharp turn I've experienced very hard downshift when reapplying the throttle. It bangs into a lower gear like an old 50's/60's era Hydro trans. Dealer says it's normal due to CAFE standards. Thank you EPA for giving me a 70+k car with a lousy trans.
Just installed my 2018 charging module and wiring harness furnished by pgamboa. Thanks to everyone for pointing me to this solution. The charger works on my iPhone X like a champ even with the Otter Box Defender.
My wife's 2016 Equinox LTZ V6 had a major electronic failure. All the sound quit working, including the radio, lane change warning, collision avoidance alarm, and turn signals. Does anyone have any idea what the problem could be? Thanks for the help in advance
I experienced the same issue. There is another setting button next to 1,2, and set. That is the setting for the seat return when you shut off the engine and open the door. I set mine the same as my seat setting. That way the seat is set for me when I enter the truck, and the seat goes back so my wife can easily exit after driving.
FYI, I just had my condenser replaced in my 2017 Yukon Denali. They are still out of stock. After waiting 2 weeks they replaced the condenser with an aftermarket unit that is NOT a GM part. I had to sign a form acknowledging the non-GM part. Good luck fellas.
Havasubum replied to carthman's question in Ask the GM TechnicianTry calling the customer service assist number (800) 462-8782. I've had really good luck with those folks. They try hard to help resolve issues.

My friend has been shopping for a new 2016 Silvy 4x4 LTZ/Z71. The dealer told him that GM has been experiencing a shortage of 2016 dashboards. There is an order cutoff sometime in June that Silverados and Sierras will have 2015 dashboards. As a consolation prize, the customer gets $200. Is that BS or has anyone heard of that. Thanks
