I have a 2000 Park Avenue with problems on the fuel door actuator. It would
fail occasionally but now has failed totally. I replaced the electrical
actuator but that didn't fir the problem. The switch seems to be making good
contact and providing a closure for the circuit. I couldn't find a reference
for a fuse for this.
Any ideas to help me get started troubleshooting?
Get someone to help you. Open the fuel door, by hitting the
manual release in the trunk, and have your helper push the
button. Does the actuator move that would allow the door to
open? If so, then it is out of adjustment. If not, then you
have an electrical problem. You will need to go back to the
button and check for volage on both sides of the switch. If you
have volage at one side of the switch, but not the other when
the button is pushed then replace the switch. If you have no
voltage on either side of the switch, then start looking for
a blown fuse, or loose wire. Since it started out as an
intermittant problem, my money is on the button mechanism.
If you do not have a meter or test light, pick one up and use

A friend of mine borrowed my car (with latching gas door) and then took it to a
gas station to gas it up, but he couldn't figure out how to open the gas door
latch. He kept hitting the correct button, but he neglected to have the
ignition key on when he did it.
