My drivers side window wont go up and down. But the switch on the right, which controls the passanger side window, works fine. so I removed the cover took out the driver side switch, and swapped it with the other switch that worked, and still doesn't go up and down. I just hear a clicking sound. so that rules out a bad switch I guess. any ideas? keep in mind this is the same control panel on the drivers side. if it was the motor, wouldn't both buttons not work??
