Shaolin --
Didn't you have a thread about electrical gremlins a week ago or so? I remember vaguely, something about that. If so... and now this new symptom is being added to the mix, I'll tell ya that I still think you have a stray ground somewhere behind your dash. The more you add these kinds of symptoms, the more I'm convinved that, that is where your problems are.
Dig into that mofo and look hard at ALL your underdash grounds. Reseat them all, cut and resolder questionable wiring and replace any splices you see.
Somewhere, you're getting stray voltage and/or not getting the grounds that you need for everything to work correctly.
I've been in this situation where similar problems occured and seemed totally unrelated. In my instance it was a single broken ground wire that ran from one of the dash harnesses to the dash chasis next to the radio. It was so very strange that all these gremlins I'd been banging my head against came down to this silly, skinny, ground wire.
