Known issues on the 1994 K1500. One recall is on the federal record, and it concerns replacement oil filters rather than factory parts: certain filters can lose their seal, emptying engine oil out under pressure and raising the risk of a fire. Owner complaints number 26, led by visibility with six, the service brakes with four and exterior lighting with three. Those systems are well served here, with wiper motor and linkage procedures, brake hydraulic and friction overhaul with its specifications, and lighting circuits laid out in the wiring diagrams along with the diagnostics for tracing them.
