TAIL LAMP ASSEMBLY HOUSING DISTORTS

VEHICLES AFFECTED: 198-8-1989 C/K TRUCKS

Some 1988 and 1989 C/K models may experience a condition where the tail lamp assembly housing can distort around the tail lamp bulb socket. This condition can prevent the removal of the tail lamp bulb. This condition was corrected in production through the introduction of a new tail lamp assembly housing constructed using a material that is less sensitive to higher temperatures. Vehicles built after the VIN breakpoints listed below have been constructed with the new material.

Pontiac East Chevrolet KE206770 GMC Truck KE531016

Oshawa Chevrolet K1206016 GMC Truck K1544010

Fort Wayne Chevrolet KZ231522 GMC Truck KZ537364

They are written to inform those 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 a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
