AC/H and dash Electrical Problems on Buick Rendezvous
11 people shared problem details
My local dealer service has been trying to fix this problem for over six months: AC/H does on and off. Either it will not turn on when I start the car and then (sometimes) it will come on when I hit a bump. Or, it will come on when I start the engine, and turn off when I hit a bump. I am only a university literature professor, but that seems like an electrical wiring short or loose connection to me. So far, the electric techs have changed fuses, changed out fuse boxes, changed controllers on blowers, and the problem is still there. Certain lights on the dash (i.e., oil/engine warning lights, A/C lights, etc.) come on erratically, but now the techs say they can't find or replicate the condition. What do I do now?!

The AC will not blow any air out. Fuses good, dash control panel and plugs good, checking on the actuators next. A few months ago the AC would stop working out of nowhere. I would mess with the dials and it would eventually come back on. It will not come on now and blow air.
car lights going out while driving at night dash lights going out or dimming sometimes when hitting bumps will cause this to happen
heat/ac will turn on by itself on high, while it is turned off. This happens when the car is turning, hits a bump and while the car is turned off with out a key in the ignition. My battery has to be jumped off every 4 to 5 days because this problem is draining my battery.
