Passenger window won't roll up

Widow is up by supplying 12 volts to the up side. Only had 3 volt to motor when pressing up. So if anyone has a wiring diagram this might be helpful thank you

Don't have wiring diagram available, but the 3v reading could be from a faulty switch. Just a thought, let us know what you find.

Connect VOM to each side of switch then turn on switch to see if volt reading is close to the same ,if it is then switch is ok if not then problem is between switch and motor.

Apologies for reviving a months-old thread, but I'm on the hunt for similar info. I feel your pain with the stubborn passenger window in freezing temperatures.

One troubleshooting tip you can try is connecting a Volt-Ohm Meter (VOM) to each side of the switch and then turning on the switch. If the voltage reading is close to the same on both sides, it indicates that the switch is probably fine.
