SUBJECT: TAIL LAMP ASSEMBLY HOUSING DISTORTS

MODELS: 1988-1989 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 GMC Truck KE531016
Oshawa GMC Truck K1544010
