My switch was not making good contact either so I cleaned it and tested it. I could not make the wipers work with a home rig of an aftermarket toggle or push/pull off /on switch either. It must take a HARD ground to operate them. One thing about electricity for sure is, you have to have an uninterrupted path to ground no matter whether it is a negative system like wipers or a positive ground like a starter. Once I wrapped my head around the way they work, the rest was simple. Thanks for such an informative thread.
Good deal. Glad you got it working....

I don't think it would either but it won't hurt anything to do it.
