Owners of some 1992 C/K vehicles may notice the upper left corner of the instrument cluster dimly lit or totally unilluminated while driving with the lights on. The most likely cause, other than a burned out bulb, is an interference between the upper left instrument panel illumination bulb socket and the instrumeht panel male electrical connector housing.
