E36 Coupe Electric Window Motor Change - Easy??

[NicoG]

About to attempt the above, is this an easy job? anything I should look out for, what's the ''spanner rating'' in the Haynes manual I dont have?

Thanks in advance - Nick

Update: Its a fookin nightmare so far, got the door card off and tested the new motor which works fine, but I cannot see how to detach the knackered one from the frame.... There seems to be no way I can even see round the back to see how it's attached (in four places)

HELP!!

Cheers - Nick

the motor comes attached to the regulator (the scissors bit) in the factory, and it's riveted on (or maybe torx on the other side...)

anyway, what you need to do is drill out the ally rivets that hold the regulator in, take out the whole lot and go to work on it, and when refitting, use nuts and bolts.

That's even the BMW way, they instruct the service stations to use bolts rather than rivets.

What is the actual problem? they go wrong in a few different ways, firstly is stopping and going back down, and thats from resistance so greasing the runners and putting a little rubber care on the rubbers helps (autoglym do vinyl and rubbercare)

If it only moves a fraction of an inch each time you press the button, and holding the button right down doesn't work, then a position magnet has fallen off inside, so the motor moves, doesn't see the magnet pass and think the window has stopped/jammed

somewhere between the 2 you should get an idea

If it make a bang and dropped down, than it has popped off a runner

E36 coupe - fairly easy.

Tip: remove trim on outside of door to reveal access holes
