Here's an interesting problem I just noticed today...perhaps someone else has/had the problem and would know what it is caused by...I was listening to an FM station, and turned on my rear defogger. The station I was listening to disappeared into a hisss, which disappeared after I turned off the defogger. The hissing noise replaced the radio station, so it was not just covering it up, but it wiped it out completely. Strangely enough, it did not happen on all of the FM stations, nor was it confined to one end of the band or the other...it was pretty random.
The car is a 2000 Maxima with original radio. I'd be interested to hear if anyone else experienced this.
Thanks! Z
