My fuel door release, the one on the driver's door handle, stopped working for some reason this weekend. I had to use the emergency release in the trunk to open the fuel door.
Does anybody know if there is fuse for this, or how is the button connected to the fuel for?

 

It's Fuse 8 (15 amps) in the passenger compartement fuse box. The same fuse also controls the trunk lid release, so if your trunk still opens with the release, it's probably not your fuse; then it's most likely the wiring between the switch and the filler release actuator (or the actuator itself).

 

The trunk lid opens fine. I guess I have to take it in to the dealer and let them look at it.
