Condition

Cause
The rear seat bottom frame may come into contact with the rear electrical center (REC)
cover. The contact/interface results in varying amounts of deflection of the fuel pump
relay (FPR). The movement of the FPR causes potential wear of the male terminals on
the FPR.

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
information.
