I just installed a new wiper switch on my 70 SS as well as a new wiper motor and pump. NO luck wiper motor still does not work. What am I missing. I have power to everything and good continuity to the switch. Not much of a electrician. Any suggestions.

Does the switch have a good ground?

Does the motor have a good ground?

I think so, but could you please tell me where they should be grounded to. Thanks for your reply

I had the same problem with my car. It turns out that after going crazy trying to figure out what caused the problem it was the ground. The bolt that provides the ground had fallen out. I had already bought a new motor, so I put it on and replaced the missing bolt. All was well.............

One of the 3 mounting bolts has a brass ground strap, make sure it's clean and has good contact
The switch also has a ground wire to the dash frame (I think)
The motor has a 12v+ ignition supply to it and the switch supplies ground to the brushes, pump and park
Hope that helps
