Why will my wipers not STOP!

What would cause my wipers to continue to run after I turn off the switch? I took the old switch out and put in another used switch that I had and still the same thing. I have to turn the ignition switch off to make them stop.

They will stop if you turn the ignition off.

I know this doesn't help you, but if you lived down here they run all the time because it's always raining and raining and raining and raining.

Just off the top of my head, isn't there a wire on the motor that must be engergized to "park" the wipers when the switch is in the off position?

Unplug the plug from the rear of the wiper switch. Turn your Ing. switch back on and see if your wipers come on. If they do I would guess that the problem is a short in the plug. If they do not, I would look to the internal workings of the wiper motor. That is assuming that all is wired according to the factory and not jerri rigged. I have also seen 65 models with a foot operated washer that when pushed in not only sprayed the windshield but also turned the wipers on, if your truck has this set up I would disconnect the foot washer set up and see what happens.

Im not sure what the slick wiper motors have ,but there is cam operated switch inside the motor . when the arms reach the bottom the cam turns off the switch and the motor stops.(when the dash switch is off) when the arms are in any place but the bottom the motor gets voltage from the internal swith so the wipers will park themselves. In some models the switch resembles a set of breaker points. sometimes they go bad and and the wipers will run constantly .

Lowell I believe you hit the nail on the head. There is a plastic gear the somehow shuts the wipers down when you turn it those off. Not an uncommon problem . I think there is a gear on Ebay right now for the wiper motor. Uncertain if that is all that it takes to repair the problem.

My truck is a 66, I will take the wiper motor out and see if I can find that little plastic gear. Thanks for your help guys and gal.

Louball,
I had the same problem with my '65 CC. It is the motor. If you get out, and 'help' the blades to the parked position as they wipe, the motor will likely shut off in the parked position.
I found this out because if I was driving on the freeway, the wind kept the blades from settling into the parked position, and the wipers would just run and run.
I added windshield washers, and now (as long as I slow down a little), a quick squirt of the washers lets the wipers run more smoothly on the glass, and they park and shut off, just because the washer fluid on the windshield let the blades move further.
The next thing I guess to do is dissect the motor, and see if you can find the culprit.

I am ready to switch to 2-speed wipers, so I hope the new motor does not have the same internal problem.

Let us know what you find!!

Dan
