Mirror Folding / Dipping issue

[mdubs9]

My mirrors are malfunctioning and it's a 2 pronged issue:

1. When attempting to fold, the mirrors will fold in then immediately unfold
2. When Reversing, the passenger side dips down, then back up, then down, continuously until I get out of reverse

What could be causing this? Is there a central computer module for both mirrors or do each have their own and need replacement?

Thanks
