Many wiper systems come equipped with more than one speed and special features like interval motions. When one or more of the system speeds fails to activate, check the proper wiring between the switch and the motor, looking for loose or broken connections.
Limit Switch
Or the washer pump may synchronise to the wiper transaction. Whatever the manner on your Ford automobile, always test for problems at the most regular source. Probation for potential basic, and then hint any effectiveness enigma to the Engine and other imaginable mechanical malfunctions.
Checking for Power
Constitute confident the wiper succession fuse or breaker is in commendable case. Then, trial for useful wire connections to the wiper Engine. Aboriginal, connect a jumper wire between a pleasant ground on your vehicle and the wiper motor and impel the Engine. Then, using a probation bright, trial for voltage reaching the Engine. Whether you detect voltage, you may remove the Engine and connect it directly to battery ability using a fused jumper wire.
Sometimes, the Engine Testament attempt when connected directly to battery power. If it does, inspect the wiper system linkage for binding. However, if the motor still does not work, you will need to replace it.
Tracing Power Throughout the Electrical Circuit
Still, the problem may lie in the circuit itself and having the wiring diagram for your specific Ford model will help you trace the corresponding wires for your tests. If you did not detect voltage at the motor using your test light during your test from the previous section, trace for voltage at the wiper switch and then at the fuse box. If power is reaching the switch, check the wire connections between the switch and the motor.
Ford Wiper Motor HandDepending on your specific Ford mould, the wiper system may come equipped with a basic development, or count a series of features. You may be able to function the wipers in one or deeper intervals. Two or another speeds may be available to you.
Also, most wiper motors come equipped with a limit switch that allows you to turn off the wiper and let the motor retract the wipers to their off position on the hood line. If your wipers stay midway on the windshield, check for voltage at the motor when this happens. If voltage is present, the limit switch broke and you need to replace the motor. Otherwise, trace that wire from the motor and the fuse panel for a loose or broken connection.
Mechanical Problems
Other common problems you may encounter with your Ford wiper system are slow-moving wipers. In this case, although it may seem your wiper motor is dying, the problem is actually found in a damaged pivot or some other obstruction that prevents the wiper linkage from moving freely. Remove the motor and closely inspect the wiper rods and pivot connectors.
