99 Pathfinder rear windows go down but not up.
The rear passenger windows on my 1999 Nissan Pathfinder will go down but not up, with both the master control switches and the rear switches. Focusing on one of the windows (right, rear window) I pulled out the motor and confirmed that it works in both directions. When unplugged, I tested the voltage to the motor and got 10.4 when the button is pressed for "down" and -10.4 when the button is pressed for "up". When plugged in and back-probed, I received around 10 volts for down but around 0 for up. Is this likely an issue with the driver's side master control or something else?
