I had the folding mirror problem that seems pretty common, and followed most of the advice online to fix it. One day, the mirror magically locked into place and readjusted itself. Here's the situation now: The right mirrow folds/adjusts normally. The left mirror doesn't fold and cannot be adjusted by the buttons on the door, however, when switching postions with the seat memory, the mirror does move. So I know the motor and connections are good. Any ideas?

Unclip the Mirror with a Trim Remover Tool.
Then unbolt the Motor and clean the Pins. You can spray some Electric / Contact Grease and Everything should be fine !

I've tried that and it didn't help. Why does the mirrow move when I change the seat memory, but not when I use the switch on the driver's side door?

Maybe you have to update your FRM3 module. Had similar problems where my windows lost their calibration after Reading Fault Memory.
Do you have an FRM3 ?

I have no idea. What is that?

[Mark625s]

If it was some control box, wouldn't it affect both mirrors?

Could it be the little switch for selecting what mirror you want to adjust is faulty?
Not making contact to select the left mirror, and this would explain why the mirror moves when switching seat memory.

I would remove the mirror switch panel, open it up carefully and clean the button contacts with some rubbing alcohol.

OK, I'll try that and see. Thanks.
