You need a new switch. The older Fords that have them on the dash with just a dial can be removed by a large nut in behind. Not to cheap for that one.

Go to a junk yard and get one if the new one is to expensive for you. ON a lot of the pre vehicles, it requires a new connector if you put on a Ford motor and if wrong wired. Also if the ground isn't correct plus you need to check the wiring from the switch to the motor.

Quick links. Wife loves it so much she hardly lets me drive it. Anyhow I was wondering if any of you have had issues with the windshield wipers? Mine work but only at the highest setting, nothing in between. Wife said that when she started the car they seemed like they were going to work, but then stopped, she moved the wiper switch all the way up to fast and they worked.

We live in california so I dont think it was a weather problem, meaning too coldfor the motot to freeze up. Could it be the switch relay that needs to be replaced, or is the motor having issues.

I read on another ford forum that the transmission for the wipers sometimes grinds out the gears thus only working at high sppeds. If it is the motor or Transmission for the wipers, can I fix this myself and how much would it cost me. If it is the steering wheel switch is that an easy fix as well? Wife says the switch feels fine, clicks and moves smoothly, doesnt feel broken. Sorry it had to be a problem that got you to join. But that's no excuse for not posting pictures in your gallery!

Sorry, too, that I can't help you with your wiper problem. It could be any number of things I imagine - motor, switch, loose wires, etc. I'm sure your dealer could figure it out but if you're out of warranty, at what cost? We need Waldo! He usually shows up in a thread to tell me I'm wrong about something so I'll put up this bait. Sounds like you need an ECU flash to get the wipers to do what they're supposed to do.

This is something you can't do yourself. Now we wait. I am trying to avoid to take it to the dealer, that would cost me an arm and a leg.

I also read that if the motor still runs, then chances are it cant be the motor. Humm any help would be welcomed.

Been looking online to see what other people have done for the same problem, and it is a mixed bag of some finding the relay the problem, others the motor, and still others the actual switch. There was a "parking circuit" that was supposed to bring the wipers back to home position when the power was turned off. This was a second circuit wired parallel with the switch on the stalk. On the vehicle I mentioned above there was a mechanical cam that was round with a flat spot just like a flat tire would look on the car.

When the power was turned on via the switch the motor would run.Our mobile mechanics offer services 7 days a week. Upfront and transparent pricing.

The windshield wiper module, also called the wiper governor module or control module depending on the automaker, is responsible for controlling and coordinating all the various functions.

When the wiper switch position is changed, whether from off to on, or from one speed to another, a signal is sent from the switch to the windshield wiper module. The control module interprets that input signal and sends an output signal to the windshield wiper motor.

When the wiper module is not working as designed, the wipers may not work when commanded, may not shut off, and may not work at the designated speed. The wipers can also start acting on their own volition with no input.

This tech article was originally posted at FordF It is primarily intended for Ford trucks but most likely also applies to other Ford models.

The next step is to remove the end cap. Carefully pry the cap off the stalk with a sharp, flat tool. Now that the end cap is off, hold the wiper switch still, and unscrew the single Philips screw. Don't slide the switch off yet! Before you slide the rotating switch cover off, place your hand under the entire assembly as shown. Be careful not to lose the spring-loaded switch detents top one is circled, the other is on the bottom. Put a nice dab of the dielectric grease on a Q-tip. Then, apply it liberally to the entire contact surface as shown:.

Next, replace the Philips screw while holding the outer barrel in. If the screw is hard to turn, remove it and try to start it in a different position.Windshield wipers are powered by a motor that receives volt power through a switched wire. Complete failure of the wipers to work can be a complicated troubleshoot, but working with a motor that still runs on one speed is less challenging. Diagnosis can be time-consuming, but it is not complex and requires only one tool.

That the motor operates at one speed confirms power to the switch is good, but the switch itself could have failed. Use a multimeter bridged between the upstream supply and each of the contacts while operating the switch.

If a reading above 10 volts is made on each contact, the switch is fine and the problem is downstream. If the reading is made only on the high-speed terminal, the switch has failed. Further, they can become clogged with atmospheric contaminants that act as insulation.

Wipers only work on high. Will not shut off until vehicle is shut off.

That the high speed -- the least frequently used -- selector still works suggests the tension has gone from the low and intermediate speed contacts. If they can be accessed and bent to create more tension this is a temporary fix at best; replace the switch.

Having ascertained that the switch is good, test the wiring harness. If the wiring harness is connected at either or both ends with a multiblock, consult a workshop manual -- many manufacturers and enthusiast websites publish schematics online -- to learn which wires and which terminals convey which wiper speed signals; draw a plan on a piece of paper showing the wire colors, terminal positions and their functions.

If you do, the wiring is fine; if you do not, the wiring has failed. Repeat the exercise with the intermediate speed. If both circuits are sound, the problem is in the motor; if they are not, replace the harness. The wiper motor could have failed; it could be receiving the correct signals from the switch via the wires, but be unable to act accordingly.

The circuits and windings inside wiper motor housings are seldom user-serviceable; obtain a replacement from a dealer or junk yard. Faulty grounds are renowned for causing a multitude of seemingly unrelated problems.

Most wiper motors have a dedicated ground wire in their harness, however some utilize the bolts securing them to the body as a ground. Trace the ground wire from the motor to its mounting point, then scour both the underside of the connector and the mounting point on the chassis with very course sandpaper -- grit or heavier is recommended -- then replace, ensuring the fastener is securely tightened.

Following the instructions on the packaging, use dielectric grease at the contact points for an even better repair. If working on a vehicle which does ground through its fasteners, remove the bolts and lift the motor away from its mount, then relate the procedure detailed above to the contact surfaces.

Some modern vehicles use a relay or control module between the switch and the motor. These components are seldom user-serviceable, and even diagnosis can be difficult for the untrained technician. If all other tests show good function, take the vehicle to a certified auto electrician for final diagnosis.The wipers only work when switched to high.
