Getting to '97 940 wingmirror motor

[rhagg]

Hi all, first post here and happy to be with you - looking forward to learning lots and getting stuck in

I recently bought a 1997 940 estate with ~200k on the clock. It's been pretty well looked after, I've got a decent list of small fixes and cleans etc but overall it runs well and nothing major seems to be popping up so far!

I am having some trouble with the electronic adjustment of the passenger side mirror. The driver side moves well but the passenger side will only go up/down and not left/right. I can hear the motor trying to move when I try to move it L/R and occasionally it will make a small jump. I don't want to hold the control for too long incase I burn out the motor.

I feel that the internal mechanism is either dirty or damaged and I want to get into the mirror body to look.
The manual says that for my model I should be able to reach around the inside edge of the mirror and just pull the mirror out - I've given this a try but I'm having to apply quite a lot of force behind the mirror and I really don't want to stress it and break it!

Has anyone had any luck getting into the motor and mechanisms? Is it just a brute-force job or am I missing something? I've read some more forum posts about this but they weren't super enlightening and I couldn't find any further videos or info about the process!

Any help greatly appreciated - don't want to rush into this job and break the mirror so happily awaiting responses! Thanks!
