While installing my rebuilt (original style non rallye) instrument panel into my 1973 Duster, I found some more electrical add-ons that the previous owner / electrical genius had added in. There was an extra control knob added into the instrument panel, but I never knew what it was for. Turns out it was for some addon kit that puts a time delay on the windshield wipers. My Duster has a 2 speed wiper setup from the factory.
Prior to changing the instrument cluster, the wipers worked fine on low and high speed, and the wipers would park correctly on their own when the switch was turned off.
But we took out the hack job of an add on time delay system and went with the original 2 speed wiring.
Except now I have 1 speed wipers. Turning the switch to low speed does nothing, I had to turn the switch to high speed and use that. And I also have to turn the wiper switch off at just the right moment to get the wipers to stop at the bottom of the windshield.
So I don't know if the original 2 speed switch had a problem or what, but I was going to try replacing it and see if that fixes it. It had a few wires sloppily soldered onto it to go to the time delay box.
Under the hood, the wiper motor has an extra wire coming off a mounting bolt. It looks like it is just a ground wire, but it shouldn't even be needed. Unless the timer delay box needed it.
