After you open and close the sunroof, does it ever reach a proper position if you start to pop up the rear?

I ask because my "88 745 GLE had a bad sunroof motor that did not stop in the proper place. I bought the car from a dealer in November, and I did not find out about the motor stop until the first time I opened the roof in the spring.

The manager at the dealer was as mad as a wet hen because I had talked the salesman into running the car through their certified Volvo checklist and the sunroof boxes were not marked BAD or OK. I got a new motor.

Several years later the motor went again and I replaced it with a hand crank. The hand crank dod not stop in the proper place and I was able to fix it by -

- cranking it closed with the roof in the wrong place

- then cranking it a bit more until the roof looked good

- Then I removed the crank and cranked it to its stop

- then I installed the crank again.

After that it worked well for years.

You might be able to do the same with a motor.
