I need some help, Please. I have a 2016 ford transit connect XLT. The windshield wiper just stopped working. I have 12 volts neg and positive at the wiper motors, but not getting the signal for them to run. Where does the signal come from. Does any one have the wiring diagram and any ideal where to go next. I have checked both motors the have power but will not work. I have swapped the motors for side to side and still no wipers. how much voltage is on the signal wire, So I can test the motors or is there a good way to test the motors. I have changed the switch on the steering column and the wiper still will not work. Everything on the switch works but the front wipers. Any help would be appreciated.
