Power Door Lock Switch: Description and Operation
SYSTEM OPERATIONThe power locks can be controlled by a two-way switch mounted in a bezel on the mirror flag bezel trim of each front door. The power lock switch controls the battery feeds to the lock and unlock sense inputs of the power lock and Remote Keyless Entry (RKE) module or the Central Timer Module (CTM). The relays that are integral to the power lock and REE module or the CTM then direct the correct battery and ground feeds to the power lock motors.
The power lock switches cannot be repaired and, if faulty or damaged, the switches must be replaced.
