The other day, my rear drivers side power window decided it would not roll back up. It rolls down just fine, and I can hear the motor working, but it won't roll back up. So, I replaced the motor/actuator and switch, and I still have the same problem! I figure it is the wiring harness now, but I don't know where to go from here. On a related note, the master power window controls only work the drivers window and rear passenger window. All the windows work from their own switches (except the drivers rear, described above) just not from the master. I tried replacing the switch there too, but the problem has persisted. Any help would be greatly appreciated.

 

Did you just replace motor or the whole unit? like cables/regulator? Im not sure if they sell seperately or whole one thing

 

there is probably a short in the wire after the master switch where it goes under the dash. im having the same problem. my RR window only works when the driver side door is open all the way, but once its closed it wont work from the master.

 

Test the Yel/Grn-Grn wire that runs between the master and left rear switch.
