Mainly three kinds of wiper problems are usually seen in vehicles. They are, wipers not working at all, wipers working improperly, and wipers not stopping.

All of these problems can occur due to some common reasons. The problem with wipers not stopping may be caused by some exceptional reasons, which will be discussed later.

In this section, let’s take a look at the common causes of wiper problems in F150 trucks and how you can handle them.

1. Faulty Wiper Switch

If your F150 wiper is malfunctioning or won’t shut off even after you turn them off, then a faulty wiper switch might be the reason. The switch is located right next to the steering column so that it can be accessed easily.

The wiper switch can malfunction for accumulated dirt and grease inside it, which will weaken the connection or cut it off entirely. It can also be damaged or severely worn out.

Identifying if the problem is with the switch or not is often no work as it’s multifunctional. It controls the lights, turn signals, high beams, and other small functions alongside the wiper.

So, if these other functions seem to work fine except the fuse, probably the problem is with something else.

● Solution:

A faulty wiper switch may be fixed by properly cleaning the parts inside. If that doesn’t work or if there is apparent damage on the parts, you’ll need to replace the switch.

Cleaning or replacing the switch isn’t a convoluted task. Contaminants that accumulate inside the switch over time are just grease. So, if you apply cleaning products suitable for cleaning greasy materials, cleaning the parts should be easy.

2. Defective Fuse

A blown fuse is probably the most common reason behind wipers malfunctioning in F150 trucks. You should find a fuse box diagram attached to the fuse box under the dash and left to the steering column.

From the fuse box, locate the mini fuse specific to the wipers. If it’s functional, then locate the relay fuse next. These fuses maintain the optimum power supply to the wiper circuit and will get blown if overload conditions occur.

● Solution:

A blown fuse must be replaced to get the wipers functional again. The fuse box will contain a lot of fuses, so locating the diagram and inspecting it correctly is essential.

If you can’t find the diagram under the dashed box, try looking into your user manual or calling your dealer. For replacement or inspection, simply use a fuse puller tool or a pair of needle-nose pliers to remove the old fuse gently.

Be sure to grip the fuse firmly and pull it straight out of the fuse box.

When replacing the fuse, make sure to use the correct type and amperage as specified in the owner’s manual.

3. Damaged or Loose Wire Connections

Worn-out or loose connections in the wiring harness or in the wiper electrical circuit board can stop wipers from being functional.

Inspect the wires in the harness that connects the wiper to the wiper motor for any damaged or loose connections. You can find a damaged connection more quickly by using a voltmeter and checking the voltages across different points.

Low to no voltage at certain points will indicate a loose or damaged connection.

● Solution:

Fasten all the loose connections and replace all damaged wires in the harness. Make sure to use the appropriate wire connectors and electrical tape to ensure a secure connection.

4. Worn-out Wiper Blade

Wipers won’t work effectively if the blade is damaged. Increased friction, lack of maintenance, and accumulation of debris will gradually wear out the wiper blades.

● Solution:

Look for any signs of damage on the wiper blade, such as cracks, tears, or missing rubber. You might need to replace the blades if they’re damaged.

If one wiper blade is faulty, it is usually a good idea to replace both blades at the same time. This will make sure that both blades are working properly and will help prevent uneven wear.

5. Defective Wiper Motor

The wiper motor is the component that converts the electrical energy from the battery to mechanical energy that moves the wipers.

A wiper motor can fail due to loose connections or damaged wires, worn-out gears, faulty control modules, and many other factors.

● Solution:

If you have determined that the wiper motor is the problem, remove it from the vehicle. The location of the wiper motor can vary depending on the year and model of your F150, but it is typically located under the hood near the windshield.

To remove it, disconnect the wiring harness and any other connectors that attach the wiper motor to the rest of the system. You’ll also need to remove all the screws and bolts.

Replacing the entire motor may be a straightforward task, but repairing it will likely require a professional consult.

6. Faulty Wiper Relay

The wiper relay can be damaged due to various electrical issues, such as a short circuit, a blown fuse, or a faulty switch. Also, over time, the relay may wear out due to frequent use.

● Solution:

First, locate the relay using your owner’s manual. Then, use a multimeter or a relay tester to test if the wiper relay is functional or not.

For replacement, get a new wiper relay that is designed specifically for your Ford F150 model. You can either purchase a replacement relay from a Ford dealership or an auto parts store.

Follow the instructions on the packaging to install the new relay.

Ford F150 Windshield Wipers Won’t Turn Off: Additional Causes and Solutions

Wipers not turning off can occur due to a few peculiar reasons besides the common ones. Let’s take a look at those causes and how to take care of them.

1. Faulty Park Switch

For many models of Ford F150, the wiper motor is started by the park switch. So, if the park switch malfunctions, the motor won’t get the necessary signal to turn the wipers off.

● Solution:

To fix this issue, you’ll need to replace the faulty park switch.

2. Continuous Electrical Supply

Your F150 wipers won’t turn off if your wipers keep getting continuous electrical power supply. This can occur in case of a faulty switch, relay, and fuse.

Short-circuit issues in the circuit board can also cause the wipers to get an uncontrolled and continuous power supply.

● Solution:

Check all the switches, fuses, and relays and replace if any component is faulty. If it doesn’t solve the issue, consult a professional to check up on short circuit issues.

History of Ford F150 Recall Campaign for Wiper Problems

As I said earlier, wiper problems have always been pretty common in different Ford F150 truck models. In some of these models, the problems were so prevalent that Ford had to take responsibility and launch recall campaigns.

Last year, a recall campaign was issued by Ford for 2021-2022 F-150 trucks. In this case, the root of the problem was faulty wiper motors which would make the wipers inoperable.

Almost 450k trucks were under this recall campaign, and the front wiper motors of these vehicles would be replaced by the dealers completely free of charge.

In previous years, 2018-2020 F150 models had a faulty wiper design that would cause increased friction while operating. This friction would constantly damage the wiper, eventually making it non-functional.

These models were also subjected to a recall campaign. The overall repair cost of this issue would have taken $600, including labor and parts costs.

FAQs

How do I troubleshoot my wiper system?

To troubleshoot your wiper system, check the wiper fuse, inspect the wiper motor and linkage, examine the wiper arms and blades, and test the wiper switch. If you are unable to diagnose the problem, take your vehicle to a certified mechanic.

How much does it cost to replace a wiper motor?

The cost to replace a wiper motor on a Ford F150 can range from $100 to $500, depending on the year and model of the vehicle and the labor costs at the repair shop.

What should I do if my Ford F150 wipers are making noise?

If your Ford F150 wipers are making a noise, it could be due to worn or damaged wiper blades, a loose wiper arm, or a damaged wiper motor. Check these components for damage and replace them as needed.

Conclusion

Ford F150 Windshield wiper problems may be common, but they’re also easier to take care of. With the help of a user manual, a proper guide like this article, and some simple tools, someone with a little experience can easily deal with most causes of wiper problems.

Remember not to hesitate to call for professional help if you need it. A professional approach to the problem can help you provide a long-lasting and reliable solution.
