another electrical gremlin
 

92 500E symptoms. Drivers window goes all the way down when pushing switch partially OR completely. Once down, there is an audible click about every 10 secs.from door. When I try to raise window, door click is audible but window won't raise. Turn key off then on and window raises fine.
Related? symptoms. A few times while cruising I have heard the auto lock system cycle two or three times rapidly. Sunroof has opened on it's own two or three times as well.
Could this be linked to auto lock system? The convienience control modual? All other electric systems operate fine. Switch is good. Can anyone help with this?
