Master Window Regulator Control Switch

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 master window regulator control switch is hardwired to the DDM. Activating the master window regulator control switch sends a voltage signal to the DDM. The DDM will interpret the signal and control the power and ground to the driver front window regulator electric drive.

Activation of any of the passenger window switches on the master window regulator control switch sends a voltage signal to the DDM. The DDM interprets the signal and sends out the appropriate message over the SCP communication network. For the passenger front window, the FEM will interpret the DDM message and control the passenger front window regulator electric drive. For the rear passenger windows, the REM will interpret the DDM message and control the appropriate rear window regulator electric drive.

The driver one-touch down feature allows the driver front window to be lowered without holding the master window regulator control switch. Activation of the master window regulator control switch to the second down position sends a separate voltage signal to the DDM. The DDM will then control the power and ground to the driver front window regulator electric drive until a switch input is received or the motor reaches a stalled condition.
