i have a 1995 318ti and the sunroof doesn't have one touch close, but also doesnt have finger jam safety... i found that out the hard way with my wrist... and it hurt... a lot.
Sometimes when people play with the windows in my car, or fingerjam them too much, the one touch will stop working, but it starts working again about 10 minutes later, or when i restart the car. Then again, if it doesn't work at all, it could be the actuator.
Which window doesnt work right?
