Ford 2C7Z-17508-AA Motor Assembly - Wiper

Remove the motor and check it off the vehicle with fused jumper wires from the battery. If the motor now works, check for binding linkage. If the motor still doesn't work, replace it. If there's no voltage to the motor, check for voltage at the wiper control relays. If there's voltage at the wiper control relays and no voltage at the wiper motor, have the switch tested. If the switch is OK, the wiper control relay is probably bad.
