I own a 2001 SLK230 R170. The roof can be opened normally, but when I try to close it, the control button flashes a red light, and I can't hear the motor running.
After manually closing the roof following a YouTube tutorial, pushing the control button again seems to work correctly; I can hear the motor running, and the triangular window rises.
Is this a problem with a microswitch? I would be very grateful if someone could help me.
