I took most of the wiper wiper switch apart and cleaned it. I took the end cap off, removed the phillips screw and took the ****, the white plastic piece with the contact points and spring out. Then I cleaned all the contact points including the one still inside the turn signal lever, then put vasoline on everything and put it back together. And the wipers are still now working right, they are doing the same thing as before. Running only on high and low speeds no delays at all, and shutting off about half way on the down swing.

Did I miss something?? Should I just replace the whole switch?

 

Never replace (or repair) anything until you're SURE it's the problem.

If you end up buying a wiper motor from Ford, be sure you get the wiring kit to convert your truck to a single connector. Aftermarket rebuilders will sell you an original-style motor with 2 connectors, like you have now.

An aftermarket MFS is ~$25.
