Trunk / Liftgate: Description and Operation

The Rear Glass Release can be activated from within the vehicle by pressing the Rear Glass Release Switch in the Accessory Switch Panel. The Rear Glass can also be released from outside the vehicle by using the Liftgate Wiper Latch Switch when the Tailgate is unlocked.

Battery voltage is applied at all times to the normally open contacts of the End Gate Release Relay from I/P Fuse #29. With the Rear Glass Release Switch or the Liftgate Wiper Latch Switch and Tailgate lock Sense Switch closed, voltage from I/P Fuse #29 is applied to the coil of the Rear Glass Release Relay.

The coil of the relay receives a ground through the Backup Lamp/Transmission Position Sensor Switch at G104. Thus, the End Gate Release Relay can only be energized when the gear selector is in the Park or Neutral position.

When the Rear Glass Release Relay is energized, its contacts close, and voltage is applied to the Rear Glass Release Actuator, which is case grounded. The Rear Glass will be released when the Rear Glass Release Actuator is energized.
