Passenger window does not lower the small amount when pulling door handle

[obthomas]

I had this problem. My window would not drop when I opened the door. The majority of searches on this site vehemently advocated replacing the regulator as the wires have a tendency to stretch in time. I replaced my regulator three times before I gave up and solved the problem by replacing the motor. Maybe most of the time it is the regulator but not in my case. FWIW.
