Cause
6014256
This condition may be caused by the tappet, as shown in the picture above (tappet and

rubber boot) (1), becomes detached making the tappet loose in the housing hinge (2)

misaligning the tappet to the lock actuator or the tappet is no longer retained to the hinge

(missing tappet). The misalignment of the tappet to the lock actuator could cause the fuel

door to not operate correctly and in some cases damage the lock actuator or lock

actuator mount (3), shown in the picture above. A missing tappet boot may also cause the

tappet to become detached to the hinge as the boot is part of the secure attachment of

the tappet to the hinge.

Correction
If the tappet or boot is missing, replace the tappet following the procedure below.

Note: Replace the fuel door if it is damaged, new fuel door comes with the tappet.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these

technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper

service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a

job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your

vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the
