Okay here goes:

my a/c, heat whatever just recently stopped working. Fan still blows but it wont blow cold air. This happens because all the lights on the control panel are off. I shut the car off and restarted it and the lights came back on ( you know the AC light and Where you want the air directed lights etc.) Now the lights won't come back on at all. Fuses seem to be good

thanks for the help

My car has a very similar problem, I just replaced my starter. I am not 100 % sure it is related but within a few days or maybe the same day. Not sure. My ac panel lights went out and hence my a/c doesn't work and I cannot adjust temp turn on defrost anything but I can adjust my fan blower speed. Also my blinkers are not working and the little light for my cruise control won't come on. It seems like all these things coincided at the same time. I have checked all fuses, and I can't figure it out. Please help. : Thanks

Check out the grounding on the entire car to ensure that when you replaced the part all grounds are on, tight and clean.

The more I think about it I think it all may have happened when I jumped another car. Any tips on that? I switched the wires up accidentally(lots of sparks), and that is more than likely the event that resulted in my current dilemma.

Start checking everything under the hood in the fuse box.

Unless I am just totally retarded I cannot find anything blown in my under hood fuse box or either of my door panel fuse boxes. I have even tried switching out fuses that I believed might been somewhere up the chain from the problem? I am about to take to a mechanic, I just don't like to be whipped like this!

I have the same problem on my daughter's car. She ran over a tire retread on the highway last week which ripped out the wiring harness under the left front wheel well. This skinned the insulation from several of the wires, burned out some bulbs and some fuses. This also ran the battery down. She had it jumped, and after that there is no fan or lights on the A/C controls. I have checked all of the fuses under the hood and swapped the relay with the window relay. Is there another fuse somewhere? I retaped all of the skinned wires and have all the lights working. All other electrical components check out. Any other ideas?
Thanks.

Both of you have sent power down the line that has taken out a component. If it is not the fuse it will probably show as a relay that got fried.

Bruce, Thanks for the reply. I agree a relay is very likely. I swapped the blower relay with the one next to it (power windows) in the fuse box and the problem did not change, and the windows still work. Is there another relay? Can you tell me where to look?

Thanks.

It ended up being the actual panel. I was getting power everywhere even to the panel so I got a new panel from the junk yard and voila, no more sweating to the oldies. $45 fix, and very easy to do yourself, just get a meter and see if it's getting that far down the line.
