To reset the moonroof, flip the ignition switch to the "ON" position. Then, press and hold your moonroof's button towards the full-tilt position. Repeat that step a second time once the moonroof is tilted upwards. After getting the moonroof to tilt upwards a second time, hold the button for an additional four seconds.

My Moonroof Won't Close or Open - What to Do

Unlock but hold the unlock button on your remote while pointing at the driver's side door. There is a sensor right there.

pinched wire..

It may be a faulty moonroof switch or an electrical short.

If this occured after trying to close the shade while the moonroof was opening, it is possible that the plastic tab that locks into the vent (and subsequently the rest of the moonroof) has been bent. I was having a similar problem where my vent would only go up on one side and stay closed on the other (and it would sometimes get stuck open). It would also prevent the rest of the moonroof from opening up. If this is the case, from what I can tell, there is no easy fix for this. Upon researching this problem, you are the only other person asking about it and zero fixes. For the time being, the vent can be closed by lifting up on one side to "unlock" the stuck tab and you should be able to put it down. After that, you should look up instructions to remove your moonroof glass to see if you can inspect the affected area to determine the cause. Here is a link that shows you how to remove the moonroof glass, but does not address the exact issue you describe.

on 1987 all you mentioned are on same fuse #11 located in fuse box below steering wheel 3rd row 3rd fuse from left next to either a blank space if you do not have power windows,or next to silver circuit breaker if you do have power windows.

My minivan driver and passenger door windows did the same. Turned out to be bad motors.

My window on my vert was doing that. Short of opening up the door and trying to do it myself, I took it in to the BMW guys at Bimmerhaus. They readjusted the window for me and it was good to go. Pretty much cost 1 hour of labor and a couple of clamps. $100+ or thereabouts.

On EX and EX-V6 models:
The moonroof has two positions: it can be tilted up in the back for ventilation, or it can be slid back into the roof. Use the switch under the left dashboard vent to operate the moonroof. The ignition switch must be ON (II).
To tilt up the back of the moonroof, press and hold the center button. To close the moonroof, press and hold the top of the switch To open (slide back) the moonroof, press and hold the bottom of the switch. Release the switch when the moonroof gets to the desired position. Make sure everyone's hands are away from the moonroof before opening or closing it.
The moonroof has a key-off delay. You can still open and close the moonroof for up to ten minutes after you turn off the ignition. The key-off delay cancels as soon as you open either door. You must then turn the ignition ON (II) for the moonroof to operate.
Hope this helps.

you are having a problem with either your power switch which opens and closes the moonroof. or either you may in fact have a motor problem with moonroof. check to see if you may have an electrical short in your system. also you also may have something wrong with your moonroof sliding armature.
