I have recently replaced the passenger side mirror on my 2002 3.2 TL. the replacement was easy but i have realized that when i put the car in reverse the mirror does not tilt downward, it tilts to the side. and when i put it into drive, it doesnt move back to its original position. i was wondering if i have to do something with regards to the computer to set the mirror up properly, or is it just a manufacturing problem? any suggestions would be great.
