I sold that truck. That thing had one problem after another. I did find that my passenger side worked but as soon as I turned on the driver side the passenger side stopped. GMC looked into the issue and replaced the module that controls it, but that didn’t fix it. They wanted more time to check all the wiring but they had my truck for two weeks already due to a cylinder misfiring. Took them more time to find parts to fix it than it did to replace the bad parts. This truck was full of computer and electrical issues. Sure hope newer models aren’t as bad.

Today I started up my AT4 and the power steering died. The stated I needed to get power steering service. After a couple of restarts, it started working again. Is this a known issue? I already have an issue with my seat cooling where only the passenger side works, but as soon as I push the driver side the passenger side stops and neither work. And the auto-stop engine doesn't work either. Taking it in tomorrow, but seems like there is some computer/wiring issue from all the problems creeping up.

Thanks...I'll give the fuse box a look first.

Nothing. No sound, no air. Just checked my girlfriends GMC Sierra and you can hear the air in her seats when they are on. Is there a connection or fuse I can check?

The ventilated seats, both driver and passenger don’t blow cold air. The blue lights come on when turning them on but no cool air from the seats. The seat heaters work fine. Any suggestions? Trying to keep from having to take the truck in to the dealership.
