Sunroof fix C900
The 88 SPG had a problem where the sunroof would not close, and partially open. I got it to where it would close within a 1/2-1" or so, enough to solve the problem for the night and at least secure the car.
I did a search of the boards and noticed a trend about the motor coming loose. Opened the hatch and pulled up the lower cover where the tire is and the sunroof motor is on the passenger's side about knee level. The three exterior bolts were ok, but underneath was a round rubber circle with 4 holes in it, looks similar to a fuel pump part, so I set it aside. There also is a sunroof crank, kinda neat, but didn't work, figured that I would have to go further.
There is a triangular metal cover and it my case, rusted bolts. Since it was sheet steel, I bent the casing enough to get the motor out and the worm gears and the motor separated. I found the problem!
Used 3 vice grips to hold the worm gear cover and the motor together and hit the sunroof switch, and it closed like magic! Even opened too! Figured that trying up three vice grips wasn't an effective use of tools, so I found the little screws that held the worm gear to the motor and replaced the screws, and it held together.
Wiggled the motor back into place and bolted the three main screws down and rebent the triangular metal part over and got it back into place.
Total fix time was less then an hour, fairly easy DIY job! If your sunroof is running slow, stops or binds when closing, check to see if the sunroof motor is secure and the worm gears are in-place. The best thing is that its easily accessible from the trunk and doesn't require you to take the roof/headliner down.
I posted this so the next time I search TSL I will find it and also hope that someone else can use the tip! I encourage everyone to post fixes, minor or major so that we can build up the database on fixes and have people from other boards search this one as a reference. The Bentley book does not cover this or at least I couldn't find it.
