Drivers window won't go down all others work fine
More than likely the switch,or bad motor.
We checked the window control module, and it was good, also changed door switches, it was good. Checked fuse good too.
Bad motor if you have done all of this.
Check fire to motor.if it is there,change that motor.Some time,s you can tap it,and make it work,but this is not a fix,
No motor is good it's very frustrating
Have you checked the wire,s to motor from switch,that is all that is left?
