Having problems with your Cars & Trucks ?
The rear ac in my 2007 Chevy Uplander turns on by itself, (the knob is by 0, not aux, so that's not the reason). When it does I can't control it, no matter where I turn the knob it stays on (on full blast). It comes & goes some days it behaves & I control it, and some days it turns on as soon as the engine starts.
