More instrument panel lamp assemblies are damaged through improper removal and installation of the cap, than from any other source.
Many owners and mechanics use a twisting movement when removing or installing the cap. This invariably results in damage to the assembly.
To remove the instrument panel light cap first turn on the instrument panel light, then pull the cap straight backward. To install, turn on the light, then line up the small depression in the cap (see "A," Fig. 806) with notch "B" in cap body and push cap straight in.
Turning on the light, lines up the tongue or groove inside of the lamp assembly with the notch in the cap body and permits easy removal or installation of the cap.
