96 rear wiper testing?

Does anybody know how to test the rear wiper on a 96 jimmy? What are the 5 wires going to the actual motor off the pcb. I tested to the power control board and got power at the 4 wire connection but didnt get it coming out at the 5 wire connection, so I bought a new pcb and now I got power at the lower part or the 5 wire harness but still doesnt work. So I bought a reman wiper motor and still nothing. I am looking for the specific 5 wires that go to motor does anybody know those wires for testing. It is driving me crazy.

Here is a link to the rear wiper motor wiring diagram.

It shows the wire colors going into the module and where they come from. Hope this helps!
