Passenger Window Power Supply

WARNING: This page is about a different car, the 2004 Lincoln LS. However, it is still accessible from the selected car via links, so may be relevant.

The REM controls the power supply to all three passenger window control switches. To protect the REM from a potential failure, the REM removes power from the common passenger window power supply when a short to ground is sensed in any passenger window control switch, associated circuitry or the power output circuit of the REM. Power is be restored to the power output circuit upon a cycling of the ignition switch. If the REM output circuit is shorted to ground, the REM immediately removes power from the common power supply circuit. If any passenger window control switches or their associated circuits are shorted to ground, the power will remain on the REM output circuit until the switch or circuit containing the short to ground is activated.
