My door mirrors don't stay folded in when press the botton. They keep popping out.

 

ok theres a small micro switch inside the mirror assembly that has a small arm
that falls off this will cause this problem. the casing for the mirror assembly is sold
seperately because you will brake the casing opening it up and putting the micro switch arm back in place.
if only one mirror is folded in and the other mirror is folded out (misaligned)
disconnect the battery (plus and minus) and touching the cables together to get rid of the serface charge (ten sec)
will cure this problem.
