Hello everyone! I’m facing a problem that is beyond my understanding of electronics. I have these volvo 740 GLE from 1990 with a right electric window not functioning or sometime only opening. I’ve discovered that the voltage at the connection with the motor was good (+12v/-12v depending the switch position) but the motor was not working. So I’ve bought a new motor which was not working too. So I havé tested it on the other door and then… It worked properly.
So my question is why the motor doesn’t work on the right side if it is not a motor problem and not a voltage problem?
