Passenger side mirror is not heating but will stil move, anyone else had this problem? is it common? Secondly, i'm finding 3/4 cm "spots" of liquid on my drive from under my car, 4 spots in the last day or two. They're passenger side near the rear of the engine bay. I wondered if it was exhaust related. Seems like water but i can't tell, if anything a slighly oily texture but then that may be contamenant.
