Notes on Intermittents

The Amber cruise "ON" indicator can be used to monitor cruise control switch status. Turn cruise control switch on and manipulate wiring and connectors. If switch or circuit from fuse to switch are open, the Amber indicator light will go out.

If the cruise control 3-amp fuse blows intermittently, turn cruise control switch on, manipulate wiring, connectors, and cruise control/steering column switch. If circuit becomes grounded, the fuse will blow.
