Normal Operation
The LH rear and RH rear window control switches receive a power input from the rear electronic module (REM) on circuit 7-AJ14A (YE/BU) (LH rear) and circuit 7-AJ24 (YE) (RH rear). The LH rear window control switch sends a passenger input command to the REM over circuits 8-AJ14 (WH/BU) (UP) and 10-AJ14 (GY/VT) (DOWN) while the RH rear window control switch sends a passenger input command to the REM over circuits 8-AJ24 (WH) (UP) and 10-AJ24 (GY) (DOWN). The REM appropriately applies power and ground over the LH rear window motor circuits 35-AJ13 (VT/BU) and 34-AJ13 (BU/RD) and over the RH rear window motor circuits 35-AJ23 (VT/WH) and 34-AJ23 (BU/OG) in order to operate the correct window motor in the commanded direction. These window motors are not smart motors and therefore have only proportional up/down operation with no one-touch feature.

Possible Causes
- Circuits 7-AJ14 (YE/BU), 7-AJ24 (YE), 8-AJ14A (WH/BU), 8-AJ24 (WH), 10-AJ14A (GY/VT), 10-AJ24 (GY), 31-DK30 (BK/OG), 34-AJ13 (BU/RD), 34-AJ23 (BU/OG), 35-AJ13 (VT/BU) or 35-AJ23 (VT/WH) open
- LH rear or RH rear window control switch
- LH rear or RH rear window motor
- REM
