03 Yukon Rear windshield wiper motor help.

[guntruck]

Hello all, my sister has an 03 Yukon Denali that has had the rear wiper motor replaced twice. Well low and behold it stopped working again so I replaced it and it still wont work. I testsed the motor all is good but now there seems to be a voltage issue. I have tried grounds and couple other things but I just cant get it to work. I searche and serached but there doesnt seem to be a wealth of knowleadge concerning this other than it is in fact a common problem. Does anyone know where I can find a wiring diagram to see what wires should be hot etc? Or any suggestions would be greatly appreciated.

Thanks

If you have (or get) a Haynes (or similar) shop manual, it will have all the wiring diagrams you need. You should be able to pick one up at your local parts store for around 20 bucks. Good luck!

Get rid of the wiper. I never used mines when I had it

This may help. It is the wiring diagram for the connector.
