Ford F150 Windshield Wipers Not Working – [6 Possible Reasons and Easy Fixes]

It’s heavily raining outside, but your Ford F150 windshield wipers not working. Well, I am here to help you fix the wipers and make your way home safely.

In this article, I will discuss about the possible reasons why the windshield wipers are not working and how to fix them.

The faulty multifunction switch is the primary reason why the wipers are not working on your Ford F150. Other possibilities are a bad fuse, relay, rain sensor, wiper assembly, and wiper motor.

Please Note: You can follow the troubleshooting guide for any Ford F150 model. Some common years include: Ford F150 1994, 1997, 1998, 2003, 2004, 2011, 2012, 2013, 2014, 2021.


6 Reasons Why Ford F150 Windshield Wipers Not Working!

Here are the six common reasons and the fixes for Ford F150 windshield wipers not functioning.

Bad wiper motor relayReplace the wiper motor relay
Faulty rain sensorInstall a new rain sensor
Damaged wiper transmission and linkage assemblyReplace the linkage assembly
Bad wiper switchGet a new multifunction switch
Bad wiper motorReplace the wiper motor

1. Bad Fuse

If the wiper and the wiper motor (30 Amp) fuses are not in good condition, your windshield wipers won’t work.

Fuses that are associated with the wiper module are in the battery junction box, aka the fuse box under the hood.

Open the fuse box and make sure none of the fuses are blown or physically damaged. If you find any damaged fuse, replace it with an appropriate one, and hopefully, your wiper problem will be fixed.

2. Bad Relay

If you have a bad windshield wiper motor relay, you’ll end up having non-functioning wipers. So open up the fuse box and test the wiper relay.

For quick verification, you can swap the relay with a similar one. If this relay swapping method fixes your wiper problem, that means the wiper relay is bad.

And you need to get a new wiper relay to solve this problem.

3. Faulty Rain Sensor

If you have rain-sensing wipers, which are working fine at low and high speeds but not functioning in intermittent settings, the rain sensor might be faulty.

First, remove the connector from the sensor. It’s located behind the rearview mirror. Then, clean the connector, reconnect it properly, and see if it fixes the problem. 

If the sensor is damaged, to fix this issue, you need to get a replacement rain sensor for your Ford F150.

4. Damaged Wiper Transmission and Linkage Assembly

If your Ford F150 windshield wiper blades are not working or stopping mid-wipe, the wiper transmission and linkage assembly might be stuck, seized, or damaged.

The main reason for such an issue can be excessive rust and dirt around the linkage of the assembly.

So open the plastic wiper cowl panel and clean the linkage properly, and see if you get the wipers back to working again.

If the assembly is damaged, you need a new wiper transmission assembly to fix your wipers.

5. Bad Wiper Switch

The most common problem of Ford F150, especially for the 2011-2014 models, why the wipers are not working is the bad wiper switch, aka multifunction switch.

So you can get a new wiper switch, and hopefully, your wipers will start working again just fine.

I have written another guide on why wipers won’t stop on your Ford F150 with more details about the wiper switch.

6. Bad Wiper Motor

The last thing you need to ensure is that the wiper motor works correctly. If your switch is OK, there are no missing or bad fuses, and the relay is working, then it must be the wiper motor you need to replace.

Especially if your 2021 Ford F150 wipers are not working, the wiper motor might have manufacturing defects.

Ford issued a recall for F150 models built between January 08, 2020 – March 22, 2021.

Around 157,306 F150 are affected by this wiper motor defect. The manufacturing recall number for this issue is 22S12, and the NHTSA campaign number is 22V142.
