Luggage Compartment

WARNING: This page is about a different car, the 2002 Buick Regal and 2002 Buick Century. However, it is still accessible from the selected car via links, so may be relevant.

The rear compartment release circuit consists of the following:

The DOOR LOCKS fuse
The rear compartment lid release relay
The rear compartment lid lock release actuator
The rear compartment lid release switch
The body control module (BCM)
The remote control door lock receiver (RCDLR)

The rear compartment release circuit operates as follows. Battery positive voltage is applied at all times to the rear compartment lid release relay. The rear compartment lid release relay is energized by either depressing the rear compartment lid release switch, or when the RCDLR module receives a rear compartment release signal from a key fob. The RCDLR then sends a serial data message to the BCM, and the BCM then provides a path to ground on the rear compartment lid release relay control circuit, energizing the rear compartment lid release relay. When the rear compartment lid release relay is energized, battery positive voltage is supplied to the rear compartment lid lock release actuator causing the actuator to energize releasing the rear compartment lid. The transmission must be in the (Park) position, for the rear compartment lid lock release actuator to operate.
