TEST DESCRIPTION

Steps 1 - 5:

Steps 6 - 7:

Steps 8 - 13:

Steps 14 - 16:

The numbers below refer to the step numbers on the diagnostic table.
7. This step tests for continuity through the 24K Ohms. resistor in the windshield wiper/washer switch. The connector behind the instrument panel knee bolster is suitable for performing this step.
8. This step tests for continuity through the delay resistors in the windshield wiper/washer switch. The measured resistance will change in sequence from high to low as the delay speed is increased. The connector behind the instrument panel knee bolster is suitable for performing this step.
