The windshield wipers may not work intermittently due to a faulty wiper motor control board. Our technicians tell us that lightly taping on the wiper motor when the fault occurs should temporarily get the wipers working again. Some vehicles were recalled for this problem and some were not. You will need to check with your local dealer to find out if a specific vehicle was included.

    Wipers started to fail intermittently, and now don't work at all.

    It used to be you could tap the wiring harness that plugs into the side of the wiper motor and it'd start back up. Now they only turn on if the temperature is below 20 degrees, and once the truck warms up--they will quit. You get the buzzing/humming, also the wiring harness wiggles probably a centimeter fore & aft... I don't think it supposed to do that.
    Mechanics want to charge $150+ to fix it... apparently the part is only $40-50.00 at O'Rielly's/AutoZone.
