First of all hope your valet button is not pressed in

Second:
Both the fuel door and trunk releases are powered from the 20A Convenience fuse (located in the trunk) and controlled from the 10A Radio fuse (also in the trunk).
Each circuit has it's own relay controlled by the PZM. So there is a Fuel Door release relay (trunk compartment relay center#2) and a Trunk release relay (also in the trunk relay center#1).
If your remote works but not the button then is the valet button, if none work but the radio works then is probably the Convenience fuse.
