Normal Operation
The passenger window control switch is powered by circuit 7-AJ18 (YE/VT). When the passenger window control switch is pressed, a voltage signal is sent from the window control switch to the REM, which powers and grounds the appropriate passenger window motor circuits in order to operate the window in the commanded direction.

Possible Causes
- circuit 7-AJ18 (YE/VT)
- passenger window control switch
