Power window not working properly

Hi Roy, I'm back. I got a new multi-meter. With the passenger door switch down, the meter reads about 12.22 volts. It does fluctuate a little bit. With the passenger door switch pulled up, the meter reads 0.00. Does this suggest anything to you?

I checked the voltage at the connector that plugs into the motor.

There are no exposed wires at the switch if the switch is plugged connected. Are you asking me to probe the wires at the connector without the passenger door switch plugged into it?

I guess you did. I have only probed as I did today, with the switch plugged into the connector and the voltage measured at the connector that plugs into the motor. It seems to me there cannot be too many thing that can be causing my problem. I know the fuse is good. I know the motor works. I know the passenger door switch is good. I know the wires between the passenger door switch and the motor are good. I'm guessing that leaves the drivers door master switch and the wires from that switch to the passenger door switch. Am I missing anything?

I never said the wires were good from the master to the passenger switch. My last text said I thought the only things left to check were the wires from the master switch to the passenger switch and the passenger switch itself. We obviously are not communicating well. I will not be bothering you any more. Thanks.

Hi Ken, thanks for reaching out. I did as you directed. The test light only goes on when I push the passenger door window switch down. It stays off when I pull that switch up. It also stays off I move the drivers door master switch up or down. This baffles me because that switch still lowers the window.

Just to be clear, are you talking about the brown wire (looks dark grey to me) that goes to the motor from the passenger door switch? I checked for power there and got nothing when I pull the passenger door switch up. I'm little confused because there is a tan (light brown?) Wire in the bundle of wires that come into the passenger door that goes into the connector for the passenger door switch.

So I activated the driver's door switch up (and down) and there is no power at the tan wire that goes into the passenger door switch. I tried the same thing with the light blue wire on the passenger door switch connector. There light blue wire gets power with the driver's door switch pulled up, but not when the switch is pushed down. Is the driver, s door switch the problem? Thanks

Ok so this was a super helpful thread! As a female a lot I can’t do on my own but I am having the exact same issue! I can’t test it myself I don’t have a meter or anything but every video I have watched points to master switch. Drivers side works fine but passenger only goes down with either switch ( master or using passenger switch) However it won’t go back up. So now it’s stuck 1/3 of the way down. Anyway, that was my burning question before I ordered a new switch. So even if both sides work going down and not up that the problem still lies in the master switch
