AP6: Check Wire Between Timer Module & Light Switch Rheostat Resistor

With the ignition key in the OFF position, disconnect the light switch rheostat resistor connector and the timer module connector. Measure the resistance of the Blue/Red wire and the Blue/Black wire between the timer module connector and the light switch rheostat resistor connector. See WIRING DIAGRAMS  . Are the resistances less than 5 ohms between the timer module and the light switch rheostat resistor, and greater than 10,000 ohms between the timer module and ground? If yes, go to the next step. If no, service the wires in question.
