I have a 2001 Volvo XC70 - can't get gas cap door opened. Lock will not release. Fuses OK. Locked and unlocked doors with key and key fob - filler door still locked. All doors and tailgate lock and unlock OK. Pulled right rear interior panel off - got hand on lock mechanism but black plastic latch will not move or slide back. Wire connection on lock mechanism seems OK.

How can I get the door open ? The car needs gas and my wife is planning on going out of town tomorrow with kids. I know a crow bar will ultimately work, but will do alot of damage !!!!

Any thoughts would be greatly appreciated !!!!
