I have a 98 Lesabre that I took in to get a stereo installed. When I got it back the AC would not go on. Sometimes when I start the car the AC goes on by itself, but the controller (in the dash) does not light up or turn on at all. No one can tell me what is wrong and I don't have the $ to take it to the dealer. Can anyone help? Thanks.

The GM Buick stereo has a circuit that comes from it and allows AC to work or light up..

Put the Old stereo back in and try it. I bet thats it.


There is a adapter somewhere..



Good Luck

Thanks, I'll try that. I'd really like to find that adapter!

A install shop has alot of those bad experiences covered.. .You might call around your area...








Good Luck
