Left Rear (LR) and Right Rear (RR) Power Windows

WARNING: This page is about a different car, the 2002 Lincoln LS. However, it is still accessible from the selected car via links, so may be relevant.

The LR and RR power windows are controlled by the REM. Operating commands for the rear power windows are received in two forms, from the master window regulator control switch over the SCP communication network from the DDM, or directly from the LR or RR window regulator control switches, which are hardwired to the REM.

Activating the LR or RR switch on the master window regulator control switch causes the DDM to send a message to the REM over the SCP communication network. The REM will then control power and ground to the appropriate window regulator electric drive to raise or lower the window.

Activating either the LR or RR window regulator control switch sends a voltage signal to the REM. The REM will then control power and ground to the appropriate window regulator electric drive to raise or lower the window. A voltage signal will only be received if the window lock-out is OFF and the REM is supplying voltage to the remote window regulator control switch power circuit.
