I recently bought a used 2013 Ford Edge SEL. My rear wiper worked when I bought the vehicle, for about 3 days. Since then, it does not. The rear washer works the way it is supposed to. The front wipers work exactly as they are supposed to as well.
I do NOT have rain sensing wipers. There are no DTCs related to the wipers/washers in any way.
I have used Forscan to monitor the input/toggle of both the front and rear wiper/washer switches. They have the same values when toggled.
I have tested the appropriate fuses and relay(s) in the BJB (#4 30A JCase fuse/Wipers, #64 20A MINI Fuse/Rear wiper motor, #55 Wiper relay, as well as #44 Rear washer relay and #82 15A MINI Fuse/Rear washer). I have replaced all fuses and relays with new ones. No change in functionality.
I have used a multi-meter to check and test the voltage to the rear wiper motor wiring harness, and have gotten a consistent reading of 12.57 volts. I replaced the rear wiper motor. No change in functionality.
I changed out to front wiper motor, on the off chance that the ground pulse signal was not being sent from it, to the rear motor. No change in functionality.
I am at a loss. Is there a way in Forscan that I can force the rear wiper to cycle? Or, perhaps something else that I may not have thought of?
