Circuit Operation

Circuit Operation
The liftglass can be opened by any of the following components: Liftgate window release switch, Door lock cylinder switch, or Keyless entry transmitter.

When the liftgate window release switch is operated ground is applied to the body control module (BCM) and a liftglass release output is sent to the liftglass relay. An open output can also be commanded by the BCM when an open input is received from the remote control door lock receiver. When the BCM grounds the relay with a commanded open the liftglass relay coil energizes and the switch side of the relay closes. Battery voltage is then applied directly to the liftgate window release actuator. This will release the liftglass. The liftgate window release actuator can also be energized when the liftgate lock cylinder switch is operated.
