I have had this problem since buying the car a few weeks ago but didn't really care since it is winter. I am hoping to repair it soon if it is possible. I can hear the motor running when moving the switch back and forth but the sunroof does nothing. Today I got a call from my wife saying that it opened (vent) but it will not close. Is there a thread that shows a repair procedure for this or will I have to replace the whole thing?
