Just the other day I noticed that my radio reception was extremely staticky.. Well today I noticed that it's crystal clear, until I turn on my rear window defroster. Anyone else have a similar problem or any ideas where to look for a solution? I'm great with mechanical stuff, but electronics and audio are a weak point for me.
