My driver's door mirror will not snap into the regular driving position.
This means that gradually the driving wind moves it out of position over time.
It can be pushed freely from facing totally away from the car thru to being folded in. The only place it snaps in, is folded-in facing the driver's window.
I have removed the painted housing but can't see how to dismantle further.
It looks like the base plate is somehow rotated out of position, but I can't see how it supposed to be positioned correctly.
There's a spring loaded metal column which forms the pivot point for the mirror, with a circlip on top. I'm afraid if I take this off I'll never get it reassembled.

 

OK, I fixed this last night. I removed the painted cover (pull out mirror glass with wooden paint stick, then 2 screws underneath, push out black plastic piece.)
Where the mirror pivots, there is a spring loaded column where the wires go thru with a circlip holding it all together. I prised off the circlip (carefull, it flies off). Then the whole metal piece can be lifted and reseated in the right position. The right position is with the mirror ot an 85 degree angle to the car body. This part is a little fiddly and hard to explain without pictures.
Re-assembly is tricky with it on the car, because you have to compress the spring and then re-insert the circlip. I used a big C-clamp, but you'll need a spacer for it to press on, and a gap in the spacer to let the wires out. (Kinda like a bottle top with a slot cut out, only thicker). I placed the circlip ready to slide on, partially sticking out the side of the spacer ring. Then when it was all compressed, just tapped the circlip on with a hammer.
Hope this helps someone.
