Re: Audio and window

Are you saying that when the speaker stops working, that the power windows also don't work? If so, it sounds like you have a wiring issue between the car and the door.

Re: Audio and window

Response is for a 93-95....

The radio and power windows are supplied 12 volt power by the Retained Accessory Power (RAP) module. Here's some info on the module, courtesy of Shoebox:

Sounds like a loose connector, or an intermittent problem with the circuit board in the RAP module.

Re: Audio and window

I had this problem. I took the body control module from under the passenger side of the dash and resoldered some pins. See this:

No problems since. Hope this helps you.

Re: Audio and window

Probably find one on eBay. Or you could open yours up and see if you can see a problem with the circuit board - loose wire/solder, broken printed conductor, etc.
