I have a 1996 C class on which the driver's window won't raise. No current goes to the motor when I push the button to raise it. As a matter of fact, no current goes to the relay in the conveniece control module located in the trunk when I push the button to raise the driver's window. I removed the switches from the console and cleaned them the tested the switch and it is good. I have checked the fuse for front window raising and it is good. Current does go to the motor when I push the down side of the button and the motor works fine. The passenger window goes up and down just fine. This problem has stumped me... Help!

 

1. Blown fuse,
2. Faulty relay,
3. Broken or disconnected wiring or connections,
4. Faulty motor.

 

The motor is good. I took it out and tested it. The convenience control module was replaced which contains the relays for the windows. Is there another relay of which I am not aware?
