hello all, im having some serious problems with the power window on my 83 300D... the drivers window will not roll down, period. i have searched on here and believe i have exhausted all threads on this. i pulled out the motor and it will roll up but not down, i tried an extra motor from a door i bought for parts and same issue... rolls up but not down. i cleaned all switches (which were very dirty/corroded) and tried the switch on another window, switch is good. i pulled the wires (1 green and 1 black) through the door tunnel and into the car by hood release and found no breaks in wires. what else could be the problem??? anyone? please help! thank you all.
