Ford Bronco Headlight Switch Knob & Shaft Removal Diagram - Hooked Tool Method

This document is a single service illustration showing how to remove the headlamp knob and shaft assembly from a headlight switch. The line drawing depicts a hand holding the headlamp switch knob and shaft, with two labeled callouts. The first callout identifies the 'HEADLAMP KNOB AND SHAFT ASSEMBLY.' The second callout instructs the technician to 'INSERT HOOKED TOOL INTO KNOB SLOT TO DEPRESS SPRING THEN PULL OFF SHAFT.' The figure is identified by the illustration reference number K17679-A in the lower right corner. From this document, a reader learns the removal technique for the headlamp switch knob/shaft: a hooked tool must be inserted into a slot on the knob to depress an internal retaining spring, after which the shaft can be pulled off (out of the switch). The document contains no year, model, torque, wiring, or part number information beyond the figure reference code; it is one page of a larger headlight switch service procedure set (uploaded alongside cluster trim panel and dash panel removal pages). It is applicable to Ford-style headlamp switches that use a spring-release knob and shaft, as commonly found in Ford trucks such as the claimed 1990 Bronco.
