Just to close off this thread,fist Thank Everyone for the help.
My feeling is that the window motor is defective,like an open in the electric motor.Motor was just replaced a month or so before i bought the car.I tried a wiggle test on the wires when the door is fully open,but no change.
When i fix the a/c window will not be that much of an issue,as it does open.
THANKS VERY MUCH
WHAT A GREAT SITE
Rich
