In my acura tl 2008 when i put it in reverse the side mirrors take turns as to when they want to work for example i put it in reverse and the driver side went down but not passanger then i drove the car into the driveway and put it in reverse then the passanger worked and not the driver. I can still adjust each of them remotley

 

Only one side tilts at a time and that's determined by where you leave the side mirror selector.

 

thabk you never knew that

 

Definitely the side mirror selector.
