Normal Operation
The LH rear and RH rear window control switches receive a voltage input from the rear electronic module (REM) on circuit 7-AJ14 (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 voltage 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.
