Vehicle: 92 Nissan Pathfinder SE-6
220,000 miles
Details: The rear passenger window will roll down, but not back up. The front passenger window will roll down, and sometimes back up.
I took the rear passenger door panel apart assuming it was the motor. I took the electrical motor apart just to see what was in there, and by accident I put it in the electrical motor back in the body 180° backwards. I hit the button and the window rolled up but not down. To test this I took the motor apart again, and reversed it 180°, and sure enough the window rolls down, but not up. I did this one more time to get the window up, and disconnected the power. The front window now rolls down, and if I try at random times I can get it to go back up.
Driver side windows front, and rear, work fine.
Question: Are booth motors failing or is there a greater problem further upstream?
Is there a relay on the right side that controls power for both windows?
Thanks
-Mickey

Motors should be good if they can go either way. The wiring is reversing polarity - you can sometimes just use a 9v battery and jumper wires and make them work either way. Test with light for both pos and neg at the wires to the motor which should alternate by up or down request.
Look for troubles at switches and where wires bend in door jams. The master control is designed to overide all and can be troubles even when you aren't touching it. Hope that helps,
