So I have been trying to figure out this power window problem. I can use the driver switch to run the passenger side window up and down, but the passenger side switch only works going down and not up. I have replaced the switch,cleaned all connections, replaced the switch panel, replaced the circuit breaker/fuse and no help. I checked voltage going to the motor and I get 12v on both wires when switched from passenger side up, and only 12v on one wire when actuated from the driver side>passenger>up. Any ideas?
