'79 windshield wiper spray function (1 Viewer)

[Idgie79]

Newbie here. Dont have owners manual. So heres a real dumb question. How do i operate the spray function for the wipers. PO said yhe sprayer didnt work. But i forgot to ask him how to even operate the damn thing .planning on rebuilding that system either by aftermarket or cross referencing the motor.

the knob that you pull to turn on the wiper will rotate clockwise? and that should turn on the washer.

if the washer pump runs most likely the small metal tube that runs inside the windshield frame is plugged. I've never been able to clear it out. trying to run a new soft line up around inside the frame isn't easy either.
quickest solution is to replace the dummy plug in the hood with an earlier one that has the sprayer in the hood.

Thanks for the advice! I think i will try the dummy plug location. That would be much easier for the time being until i pull the hardtop off to replace the weather stripping .

The switch function for the sprayer is really kind of silly. The switch shaft has a part that sticks out a little, and that little ear touches the side of the switch housing and completes the circuit. Steel-on-steel contact as I recall. If the pump motor doesn't work, and you know the motor is good, then you might have to scrape the steel "contact points" at the switch to get a connection. I had to do that on mine. Steel isn't the best material for contact points.

As soon as it cools down out im headed outside to work on the cruiser. I will definetly inspect all thr contacts and ohm out the motor. Thanks for the info .
