Hi Maurice, 

I had a very similar situation on my 91 200q with the passenger window 
being reluctant to go up. It could normally be persuaded with the switch 
bumping as you describe, but finally one day would just not go up. I had 
replaced the driver's hinge-area door wiring last year, so I went ahead and 
soldered in new passenger side wiring even though upon inspection they 
didn't look as bad as the driver's side ones. This seemed to fix it at 
first, but the symptom returned after all the rest of the wires were done. 
Directly jumping the regulator indicated that it would always move, so if 
it wasn't the wiring it must be...the switches. They had seemed to beep out 
ok, but since the current always has to return through the driver's side 
switch I carefully pried it open, cut the plastic seal and sprayed in some 
DeOxit contact enhancer. No reoccurrence of symptoms yet, 2 months later...

HTH,
