It's been a while since I've posted, but I've been lurking around from time to time. Recently my sideview mirror on the passenger side is always dipped even when not in reverse. I'm able to bypass this by flipping the switch on the mirror control to the other side(disabling the dipping feature). So its clear the mechanism is functional, but some wire has likely broken loose somewhere. If that's the case, it could involve an extensive search. Aside from checking at the mirror, where else should I look? Where does the circuit for the mirror complete?

Also of note, my car was an auto, but a PO did the manual conversion. At some point whatever detects 'reverse' and initiates the mirror dip mechanism had to be altered to work with the manual transmission. I'm not just sure where that would be.
