Turn Signal Noise

[dsmazz]

I have an Alpine unit that I installed about six months ago. Everything has been fine, until the last week or so. Whenever I use the turn signals, the sound is replicated through the speakers. This does not occur on FM or CDs, and the weaker the AM station the more prominent the noise.

 

There's also a static noise through the speakers when using the passenger window switch from the driver's side (but not the driver's window switch), or if I turn the headlight switch, I also get static noise through the speakers.

 

I'm suspecting a bad ground. (This truck has had a ground problem since day one, and has eluded everyone. But I think that's another story.) There's no alternator whine, just the ticking sound from the turn signals.

 

Thoughts or ideas appreciated. - Thanks

that was my first thought...but...could have a wire touching the metal frame in the dash...could be really small

AM radio stations are prone to picking up unwanted electrical interference, especially the weaker stations. Since it doesn't do it when listening to FM or a CD I will have to say its the nature of the AM stations.
