Rear Power Window Lockout Operation

NOTE: Power window lockout switch disables REAR passenger window switches only and has no effect on the operation of the FRONT passenger window switch.

The rear window lockout function is operated from the driver door switch (DDS) through a GMLAN message to the body control module (BCM). When the BCM receives an active lockout command, the rear door power window switches are disabled. The lockout control circuit from the BCM supplies the accessory/retained accessory power (RAP) voltage to the rear window switches while the lockout function is inactive and removes the supply voltage to activate the function. Once activated, the lockout feature will remain in effect until the ignition switch is cycled or the DDS receives another power window lockout switch activation.
