Installing a window motor - 89 911 Cab.....
 

I think I have to install a new window motor (one last test - check power at the motor). Anyway, I know how to take the door apart but have never replaced the motor. Is there any advice that you guys can give me regarding its removal? Andrew

Nothing to look out for, a simple replacement but takes patiences.

Ok. I can't figure out how to disconnect the wires from the motor. I tried but am worried about breaking something. I also loosened the 2 hex bolts above the motor (compared to new one for placement) but nothing is happening. It looks like only those 2 bolts are holding it in place. Andrew

IIRC, there are 3 bolts holding the motor to the regulator. Also, there is a sort of a clip on the wiring connector, which will release with a firm bit of wiggling. Good luck, and be sure to grease everything, and remember to align the window to your top before you button everything back up.
