No, that wouldn't have anything to do with it.

If you have a jumper wire with alligator clips on both ends clip one end to the wiper motor (you will need bare metal to clip it to, but not the mounting bolts) and the other end to a good ground on the back of the dash (clean metal) then turn it on and see if it will work. It is very important to have bare metal on both ends.

Let me know what happens.
