Rear Defroster causes static on my radio

November 15, 2004, 09:29:34 AM

Hey guys, I have a non-ford problem here. My 99 grand prix has a wierd problem, whenever you turn on the rear defroster the radio gets alot of static, turn off the rear defroster and the static goes away instantly...

Is there some kind of filter or something I can put inline to stop this?

factory radio with a alpine 5 disc changer. I bought the car with the alpine in it, I think the alpine was a dealer install cause theres a manual with the alpine logo and the pontiac logo on it.. Also it uses a FM modulator, I think thats the source of my problem I have to find the modulator and try disconnecting it. Was just curious if anyone heard of a problem like this before

If it's an FM-modulated changer I would look at where it patches into the factory antenna cable. You may have a poor connectioon, or the modulator itself may be picking up EM interference and re-transmitting it through the antenna.
