I have a 79 300D and just the other day I was running errands and had the windows rolled down and then after one stop I get into my car and try to roll the front passenger window down and it won't budge. I took the door panel off and when I push the switch, you can hear and feel a clicking that is right before the motor, but the motor is not turning as I took the cover off to look at it. I called my mechanic today and he said it most likely isn't the motor, might be the regulator jambed up and said he'd just have to look at it, but I don't have time to take it into the shop since I need the car everyday. Tell me how to test the regulator and get the stuff out of the door without the window crashing down. The window is rolled up as mentioned before. I just want to get this fixed ASAP b/c w/ no automatic passenger window it sucks to roll down just my side.
