i have a 1983 300d greymarket w/ electric front windows. when i was working on the speedometer i shorted out the clock fuse. when i got everything back together the drivers window will not work. the passenger window has not worked since purchased 2 months ago. the drivers window is in the down position. i get power to the terminal block before the motor. when i hit the switch the voltage will drop off on one or the other side of the terminal, but there is no action from the motor
