Mercedes-Benz W201 sunroof faults: gap, will not close, will not open
The rear edge of my W201 sunroof stays up in a gap, how is the roof adjusted?
The position of the roof is adjusted with the adjusting screws (8 mm) on the rails. Hold the roof by hand in the correct position while tightening the screw. Also check that the headliner or seal is not preventing the rear edge from seating. If the wind deflector does not lower, it is adjusted with a small adjusting screw.
W201 sunroof droops, ratchets or will not close, what is the fault?
The cause can be a broken roof cable, in which case a ratcheting noise is heard and the roof stops in the wrong place. The cable is released from the roof's lock and pulled out from the cabin side, and the new one is installed along the same route. If the cable is intact, the roof can be cranked closed by hand.
W201 electric sunroof does not work or does not open, what should be checked?
If the interior light dims when the roof is operated, the mechanism is seized; otherwise the motor brushes may be worn. The mechanism and motor are behind the boot trim. A seizure often frees up with cleaning and lubrication, but the trims have to be removed and the job takes almost a day.
