I bought a 1995 940 with a moonroof last week. The owner had some shop disable the moonroof years ago because he was afraid of it being stuck in the open position. I took the cover off the motor and opened the moonroof with a flat bladed screwdriver. There is a small screw inside the larger flat bladed screw that fell out and I found out that the larger screw couldn't be turned without the small screw being depressed (it is depressed when a screwdriver is inserted into the large screw). I checked power to the dash switch and power was there. I later found that when I had manually opened the moonroof to the vent position (moonroof rear elevated and in place), there was a clicking in the motor. I assume this was a safety relay that opens contacts to the motor when the vent position is open to stop the motor. But, this proves that power is getting to the motor. I have the wiring diagram to the motor but it does not include the microswitch I have heard mentioned in the FAQS.
1. Where can I get detailed moonroof information on the moonroof adjustment, electrical, mechanical and operation?
2. What is the function of the little screw
that goes in the middle of the bigger screw?
Here is the motor
3. Where is the microswitch?
Thanks
