01 s430 passenger side mirror issues!
 

I have an 01 S430 and ai just got an amp and speaker box installed. During the install the installer disconnected the ground from the battery and when he reconnected the cable the passenger side mirror went in (closed) and wounldn't stop trying to look down! Kept working eventhough the car was turned off...and wouldn't respond to the controller. Any ideas how to fix this problem?

sounds to me like hes got something wired in to the electrical system incorrectly. that should not happen. it definatly should not be working with the car off! tell him to check his work. he probably wired power or ground incorrectly.
