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. The condition can be remedied by removing only enough material from the instrument panel connector housing area to eliminate the interference.
