My driver side window wont go down. Since i purchased the car it has never worked. All other 3 windows go up and down with their own switch. The rear driver side works on both switches.

I have changed the motor and regulator. Switch and fuses. Still nothing has worked. If anyone has any suggestions or ideas as to what might be the problem... please help!!! Thanks in advanced!

 

Broken wires in the harness that goes between the driver's door and the rest of the car.
