Hey peoples. I just recently got a 04 Civic and really need some help. When I turn on my radio and then turn on the rear defroster, I have static. Static occursonly with the radio. The radio works fine when the defroster is off. I just had my rear windows RE-tinted because there was a line in the first set of tints. AndI also had a Pioneer HU put in. The guys from the tint shop say that the tint is non-metallic & shouldn't cause static. Could this be a grounding issue? But if it were, wouldn’t I have static on the radio all the time?
