The fuel door isn't working. The motor seems to be running. It opens when I press the gas/door button on dash but then won't let me shut it again. My mechanic said: I can replace the motor but that doesn't seem to be the issue, I'd hate to make you pay for the motor and it might not solve the problem. I've had several people look at it and nobody can seem to figure out why it won't re-latch. Help!

 

Any suggestions would be appreciated!
