Circuit/System Description
WARNING: This page is about a different car, the 2009 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
The fuel door release actuator shares the circuit with the driver door latch assembly. The body control module (BCM), upon receipt of a lock switch lock or unlock signal, will switch the appropriate door lock actuator, as well as the fuel door release actuator control circuits to battery positive voltage. The opposing side of the door lock and fuel filler door release actuator is connected to ground provided by the I/P fuse block through the other door lock actuator control circuit and the doors, along with the fuel filler door release, will lock or unlock as commanded.
