Have a little difficulty figuring out what's going on with my front passenger window. I've checked to see if there is voltage going to the motor and it will only get voltage from the passenger side switch and not the master switch. The motor will not make any type of movement even when I switch the passenger switch. Still trying to figure out if it's the motor or maybe a ground wire problem. Any suggestions?

 

How many wires go to the motor?

If its two wires, then the polarity will swap between going up & going down.

Have you tried powering up the motor directly?
