A general electrical question
Hi, nothing to do with amazon or PV but a general question that I know that some of you experts might answer. The front NS power window on my 940 gle will open the window but not push it back up. Does the switch just reverse the polarity of the motor to enable it to lift or lower. If it does one but not the other would it be safe to assume that the motor is OK but the fault could lie in the switch? Diagram attached
