This has happened before when I was re-doing the wiring behind my glovebox - sorta made the connections lose but after some pushing it was working fine again.
Now I have a bit of a problem. I tried to check the folding mirror button wiring and it seems fine. Made sure it was contacting at both ends - didn't work. Pulled apart the door and glovebox - use some new wiring to test and its still not working.
The other buttons on the mirror switch work (mirror adjustment & stuff). I'm not sure what is wrong...
