Have static in radio side of sound system. Check and see if it comes and goes when you turn on fog lights. Had this happen this morning. Thought it was radio station drifting! But when I, turned off the fog light switch off it went away. Will check it later think there might be a shorted bulb. Artie

 

Artie,

I have the same problem. I do have one foglight out though. Too busy to check it out, I'm gonna try replacing the fog light bulb first since that's the easiest step.

 

Sounds more like a loose bulb or connection to me.
Good luck!

 

Check your connections, sounds like you have a loose ground somewhere.
