FUEL LID will not lock
somehow, I noticed that my fuel lid will not lock even when the car is locked (remotely or from inside).
I read from a forum saying that I have to check the fuse for the fuel lid lock. I managed to inspect FUSE #15 on the Fuse box inside the trunk left pillar, but fuse is also OK.
Could there be any other reason why the Fuel lid is not locking?
Thanks

Your fuel lid is unlocked by a plunger which retracts when pressure is produced by the pump PSE under the rear pass seat. The doors, trunk and fuel all share the same line. When vacuum is applied they are locked. This pump roduces pressure for the lumbars, vacuum to supplement engine vaccum to activate HVAC diaphrams, I some vehicles it supports the back up rods, and head rest release, on non electric headrests. It does have timeout features, when it can not produce the required pressure or vacuum in a given time. The lock/unlock timeout is shorter than the secondary consumers like lumbar or HVAC.

as described, everything linked to the pump PSE seem to be working perfectly except for the Fuel Lid Lock.
Could it be possible that the lock mechanism is stuck?
I read in the manual that there is a mechanical procedure to unlock if it does not open.
maybe there is a procedure to do the reverse?
