M3 mirrors

[Lucifer]

E36 motor in M3 and standard mirror are the same. I have done this before and cant remember if there is a left and a right. Im 90% sure they are made to be used in both mirrors.

U sure standard mirror motor are the same as m3.might try swap old motors from standard one so

was also going to say the same but not 100% either.
Failing that left right shouldn't be a difference.
That would be just poor design and another factory line for no reason.
Have you checked if part numbers are the same?
