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?!

Dash board lights going crazy and every time I hit a bump the radio comes on and off the gas gauge does not work. Really the dash board does not work.
50th

ac and heater blower fan not come on

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.

dash and random electrical problems windows an locks, air, fuel gauges etc, just bought; took back to dealer, they have had it for two weeks they say its the computer its bad and have sent it out to be rebuilt....its crazy i'm sick of waiting for it just excuses why its not ready.....says its a special edition and difficult to find new computer. but i think they just don't want to buy me a new computer! frustrated!!!!!

if I am able to start my car while driving my dash lights and all the electrical Flickr and make a sound like a CD is stuck and then like almost all out

Dashboard light goes out also radio gas gauge broke as well

fan will not work on high, no problem on other settings

car lights going out while driving at night dash lights going out or dimming sometimes when hitting bumps will cause this to happen

same prob. heater blower stops working until I hit a bump

RPM, gas, and MPH needles don't work. Radio does not work.

My fan switch is stuck on 2nd speed, will not turn at all

a/c turns on and off while driving

ac controlssometimes work or if i hirt a bump

Head lights randomly flicker. Battery light on ( brand new), service angine soon. Air works occasionally.

Ac/ randomly goes on and off. Air blows cold fan won't kick on

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.

Air-conditioner heater shuts off randomly

AC/heat stopped working. It stopped first for a few minutes and I turned the engine off, removed the key and waiting for 3 minutes before turning the engine on. It worked but stopped completely 2 days later. The AC indicator shows the light when turned on, but no AC or Heat activity.

Heater controls are intermittent, sometimes don't work, new control panel?
