I have a 03 vert I just purchased. The right qtr window does not go down at all and the left qtr window randomly operates. What should I check or replace 1st? should I just replace the drivers switch first? how do you check if the motors are bad?

Thanks

 

I do not think the windows are fused individual. Most likely a bad motor. Pull the panel to access the motor. Using a digital volt meter, check for power at the motor plug when the switch is operated. Power there....replace motor. No power, look into switches or wiring.

The power is reversed for the different directions so check both directions.
