My rear wiper quit working sometime back and Im just now able to start tying to diagnose is. The rear washer does not work when the center button is depressed either. I have 12 constant and the orange wire at the plug for the wiper. I also have 12v the #9 port under the rear seat. My initial thought is the wiper motor is shot but with washer not responding either im torn between the motor or the switch. (both previously have worked) Any input on this would be helpful as im not wanting to just throw money at it. Im also not trying to beat a dead horse with another wiper thread. I have read through them but cant find a clear answer.
