W210 E class buzzing noise
On my 97 E420 Sport, there has been a constant buzzing sound coming from behind the sunroof switch area on the roof. It comes on and off with the climate control unit. It stops several seconds after the car has been turned off but goes on when the key is in the on position regardless of whehter the climate control is set to "off"or a temperature. Anyone know what to do about this? It's driving me crazy?!
