Moisture Sensing Feature Inoperative

TEST DESCRIPTION

Steps 1-10:

Steps 11-20:

Steps 21-25:

The numbers below refer to the step numbers on the diagnostic table.
11. This step tests for continuity through the 24 K Ohm resistor and 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
12. This step tests for the wipe command from the moisture sensor. The signal voltage will alternate from approximately 0.03 volts to 7.0 volts when the windshield has sufficient moisture accumulation to activate a wipe command.
