Carl thanks for the kudos, but it was nothing to assist on the project. BEAUTIFUL car btw. I seem to get alot of photos of the wiper motor on the firewall and rarely get to see the whole car LOL THANK YOU!
Shouldn't have to change any wiring, three speed motor, three speed switch and three speed crank arm, part number 2822272 for an A body, three speed nylon bushing, that's it, whalah converted :-)

I wouldn't recommend drilling a hole and adding a little oil. I'm making an assumption this is a three speed, but if it's a two speed, here's the bench test...
I can't read the numbers on the cylinder, boy I wish I could, maybe in my younger days LOL But it's a three speed/variable speed depending on the switch. If you have a three speed switch with three very distinct positions it'll operate as a three speed, if you have a variable speed switch, it...
Variable or three speed wiper motor with a two speed switch will give you high speed only and the motor will park only where you turn it off at. You get the same scenario if you have a two speed motor and a three speed switch. So you can get a very basic operation, HIGH speed and you'll get...
Since you're kind of mismatched there, I'd check the crank arm also and make sure you have a three speed/variable speed crank arm. It'd be a shame to get a good working switch and find out there's one more piece of the puzzle to solve and a two speed crank on a three speed motor can bind the...

Many thanks to Jim at JSRestoration for that information on testing a switch.
What's the motor doing when it's run through the switch?
