1992 Buick Park Avenue V8 Two Wheel Drive Automatic 100+ miles

I am working on a 1992 buick park avenue with windshield wiper problems. When the wipers are turned on at any speed nothing happens at all! I have checked the fuses and relays and the switch on steering column and everything is ok. I even ran ajumper wire to motor and it works. HELP!

My info shows a purple wire at the wiper motor module. This carries voltage for the highspeed setting. With the key turned on and the wiper speed set on high, that wire should be hot, is it? If it is, check the black wire for ground.

Did you check to see if one of the fuse terminals, where the fuse plugs-in, is hot? It goes hot when you turn on the key.
