When I go into reverse, the passenger side mirror tilts down, but when I go into drive, half of the time, the mirror does not tilt back up. Any help?

This also happened to me one time. Make sure that the little mirror switch on the driver side door..above the window switch... is placed in the middle of both mirror symbols and not to just 1 particular mirror. Hope this helps and you understand what I mean

 

Something else must be wrong as having the mirror selector switch not in the middle alos prevents the mirror from going down too.
