The passenger side power window would not go up so I replaced the motor. The new motor is doing the same thing. Only goes one direction. I have tested the switch but am not sure I am testing it correctly. When testing the power to the motor with both test leads plugged into the motor leads, I push the button down and get no voltage, up I get 12 volts. You think it is the switch? If so would it only be the passenger side switch?

Thank you for your help

Welcome to the forum, yes, I think it is the passenger window switch. Because it is a reversing motor, the two wires take turns being voltage or ground, depending on up or down. Voltage to the passenger side switch is not dependant on the master switch. The voltage wire is yellow.

Does it make sense that the drivers side switch will not work the window also?

When you said, no voltage, were you talking about the passenger side switch? The voltage circuits are different, depending on which switch your using. If the passenger side switch is faulty, you may not be able to operate window no matter what switch your using? I'd have to check wiring circuits.

Yes I was only talking about the passenger side switch. I found the hot lead on the switch and with a meter checked the resistance of each leg of the switch. I also plugged the switch in and checked for voltage at the motor connection. (Blue and brown wire) When pressing down I had 12 volts, when pulling the switch up I had no voltage. I did not check that with the drivers side window. I also took one lead of my meter to ground and checked the two motor wires. When I did it that way it did show 12 volts both ways. But I understand that the correct way to check them is with one lead to the brown and one to the blue.

Again thank you very much for your input.

OK, If I understand correctly? The voltage circuit at the passenger side window motor is good, But, ground is controled by the master switch. Using only the master switch, I believe both voltage and ground is controlled by the master switch.

If you want the passenger window to go up, using the master switch, the lite blue and dark blue wire should be voltage. The tan and brown wire should be ground. That is the way I understand it.
