^ No. But it happened quite some time ago. SWMBO didn't mention it to me. I noticed it when in her car as a passenger about 4 weeks ago. Since then, it's been held in place with some duct tape. Useful stuff, duct tape ... :biggrin:.
Have just spent about an hour examining it via the gap between the loose mirror and the mirror fairing.
The mechanism is this:
1) there are two electro-mechanical actuators, one for up and down, the other for side to side (R/L). these are offset from centre so that they exert leverage around a central fulcrum;
2) the central fulcrum, consisting of compressible fingers on the fairing part that clip into a socket of the back of the mirror assembly itself, forming a ball and socket connection;
3) four open finger clips at top and bottom of the ball and socket joint, two each for up/down, R/L. These attach the mirror holder back to the fairing internals, and locate the ball and socket joint in place. There are four cylindrical bars on the mirror back that clip into four U-shaped clips on the internal mechanism that's screwed onto the inside of the external mirror fairing.
What had happened is that some forceful or rapid manual movement of the mirror had caused the finger clips described in (3) to come apart, which in turn allowed the ball and socket in (2) to come apart, thereby allowing the mirror and backing to flop around while still attached to the two actuating pistons described in (1).
After calculating what I reckoned was the correct position to line the mirror up with the internals, I exerted quite a bit of force in the centre of the mirror with the palm of my hand, pushing the ball and socket back together and clipping the cylindrical bars back into the U clip fingers.
Hallelujah Brothers (and Sisters ... ).
The mirror works once more ... :ebiggrin: :biggrin:
A further 15 minutes cleaning the remains of the duct tape adhesive off everything, and not a penny needed to be spent! I had visions of having to buy a new mirror, and then having to rip the door apart to fit it ...
