Test Description
The numbers below refer to the step numbers on the diagnostic table.
-
This step tests for continuity through the 24K ohms resistor in the windshield wiper/washer switch.
-
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.
