I have a 87 300D turbo and the the front passenger window and sunroof stopped working. For the window I checked to make sure that it wasn't the switch and made sure it wasn't the fuse, the only other thing I can think of is the motor. Does anyone know of anything else that might be causing the problem or if it is the motor, does anyone know of a place i can buy a new or used motor for a fairly cheap price. With the sunroof I have no idea what to do.

 

you need to confirm first if it was really the motor.
open the door lining and use direct voltage to actuate it.

on sunroof... does the motor works everytime you actuate it?

 

Thanks I'll try that.
