Power Door Lock Switch: Description and Operation

SYSTEM OPERATION
The power locks can be controlled by a two-way switch integral to the power window and lock switch and bezel unit on the trim panel of each front door. The power lock switch controls the battery feeds to the lock and unlock sense inputs of the high-line Central Timer Module (CTM). The CTM then relays the correct battery and ground feeds to the power lock motors. A Light-Emitting Diode (LED) in the paddle of each switch is illuminated whenever the ignition switch is in the On position.

The power window and lock switch and bezel unit cannot be repaired and, if faulty or damaged, the entire switch and bezel unit must be replaced.
