Fuel Fill Door Description and Operation
The fuel door latch 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 a fuel filler door release actuator control circuits to battery positive voltage. The opposing side of the door lock and fuel filler door release actuators is connected to ground 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.
Circuit/System Testing

1. Ignition OFF, disconnect the harness connector at the fuel door release actuator.
2. Test for less than 1 ohm between the control circuit terminal 1 and ground.
?‡'
If greater than the specified range, test the control circuit for a short to voltage or an open/high resistance.

3. Test for less than 1 ohm between the control circuit terminal 2 and ground.
?‡'
If greater than the specified range, test the control circuit for a short to voltage or an open/high resistance.

4. Connect a test lamp between the control circuit terminal 1 and control circuit terminal 2.
5. Ignition ON, command the doors to LOCK and UNLOCK by using the door lock switch. The test lamp should illuminate while commanding the LOCK and UNLOCK states.
?‡'
If the test lamp remains OFF during either command, test either control circuit for a short to ground.

6. If all circuits test normal, test or replace the fuel door release actuator.

Component Testing

1. Ignition OFF, disconnect the harness connector at the fuel door release actuator
2. Install a 15A fused jumper wire between the control terminal 1 and 12V. Momentarily install a jumper wire between the control terminal 2 and ground. The fuel door release actuator should perform the LOCK/UNLOCK function.
?‡'
If the function does not perform as specified, replace the fuel door release actuator.

3. Reverse the jumper wires. The fuel door release actuator should perform the UNLOCK/LOCK function.

?‡'
If the function does not perform as specified, replace the fuel door release actuator.

Remove the rear compartment side trim (right) panel. Refer to Rear Compartment Side Trim Panel Replacement .

Hello: I have bad news for you, if you run the actuator without it connected to the door the actuator is ruined, it will have to be replaced. After replacement the system has to have the doors (actuators re-calibrated.) re-calibrated. This is done with a Tech 2, A GM special tool.
