Hey all, I just bought an 87 300e and noticed that the passenger side mirror can't be adjusted (even though I hear the power window motor working). The housing is firmly attached to the body, but the mirror flutters around (back and forth) when I'm on the highway. Yesterday, I lifted an edge up to see what might be out of place and noticed a crossbar on the backside of the mirror. Is this supposed to mate with the crossbars in the housing? I didn't want to push too hard and break the glass. Anybody run into a similar problem? Thanks!

They do snap together, but it could very easily have one of the mating surfaces broken. 124 mirrors are very easy to swap out though, if you can find a used one.

Pete,

I had my car detailed and sometime afterwards, I noticed that the mirror motor would not tilt the mirror outwards. Up, down and in work fine. When I press the console knob to move the mirror out, it does not move. Is this fixable? How do these "mating surfaces" fasten anyhow? Care to guess how he could have damaged it?
The mirror stays put during driving, but after the door closes a few times, it will move in and I'm looking down the side of the car once again. argggh!

Anyone got a schematic of how the innards work?

Thanks for the diagram.

From #17, it looks like the motor mates to the mirror in two places. I'm confused why I can work the side to side in, but not out. Why is it "half broken"?
