How Do Windshield Wipers Work?
No wonder you have used windshield wipers several hundred times during bad weather conditions, but have you ever imagined how do windshield wipers work? Not really, right?
Because who bothers about its functioning when it delivers the required work efficiently? But for those who do not know, a windshield wiper is not just turning the switch and wiping the water; it has more to it than the eyes meet, and a lot goes behind when you turn the windshield wiper.
So, how do auto windshield wipers work?
A car’s windshield wipers are connected with a single lever and pulley system. When you turn on the wiper, the blades move together because of the lever. Although the timing and pattern of both wiper blades are different, they work in unison to promptly clean the water and ice from the windshield.
The rubber squeegee in the upper part of the blade moves back and forth, and there is a pivot point that also allows it to go up and down, making the cleaning process easier and more fulfilling. The mechanism is simple, but if there is a glitch, it can malfunction also. So, this was all about how auto wiper works on your cars!

Why Won’t My Windshield Wipers Turn Off?
Undoubtedly, the windshield wipers are one of the most crucial components of any vehicle. They are specifically designed to keep your windshield clear during unsparing weather conditions, such as rain, sleet, snow, etc. However, sometimes, windshield wipers (sometimes one and sometimes both) can malfunction and fail to turn off, even when the weather has cleared up, and you don’t need them.
If you’ve ever been caught in a situation where your windshield wipers won’t turn off even after trying all the usual tricks, you know how frustrating and dangerous it can be. Isn’t it?
But don’t worry; there are several reasons why your car’s windshield wipers might not turn off. It can be due to a faulty switch, a malfunctioning relay, or a damaged motor.
Here, we have listed all the common causes of windshield wipers that won’t turn off and provided step-by-step instructions on how to diagnose and fix the issue of windshield wipers running when turned off. Here we go:
Faulty Relay
A faulty relay is one of the primary reasons why the windshield wipers won’t turn off. The relay is the internal electric switch mechanism, which is generally a small box placed under your car’s hood, along with other similar relays that control the vehicle’s electric components.
If there is any fault in the electrical relay switch, the wiper either shuts down entirely or keeps running unendingly; there is no in-between. But the silver lining to this problem is that you can always change the faulty relay to a new one with minimal costs.
So, if you wonder why won’t my windshield wipers turn off even when I don’t need them, consider a faulty relay to be one good reason!
Broken Windshield Wiper Control Switch
The stalk switch on the side of your steering wheel controls the turning on and off of the windshield wiper. It also has a few speed settings that help better clean the water according to your requirement. But the internal circuits of the switch are a bit complex.
When you use the switch quite often, it can lead to the failure of any such internal circuits, which is why the windshield wiper won’t turn off even if you try to turn it off using the stalk switch.
But changing the switch is not as easy as changing the electric relay as you have to remove part of the steering wheel to do that! No wonder, with an expert’s help, you will successfully pull it out!
Faulty Park Switch
Are you still wondering why do my windshield wipers come on by themselves? Well, consider this to be another significant reason! The faulty part switch is also responsible for continuously running the windshield wipers in your car.
The park switch is inside the motor that controls the movement of the wiper. For the unversed, this park switch controls the powering on and off of the wiper and governs the electricity that flows through the system.
And when the park switch malfunctions, it will draw no current, which will eventually send signals to the wipers to get turned on, and it will continue to run until the entire motor is replaced!
Bad Wiring
If you are breaking heads thinking why my windshield wipers won’t turn off, then stop worrying and read the next reason! Bad motor wiring or a loose connection of the wire can lead to such faults quite unanimously.
And the most challenging part about such faults is that it is not too easy to diagnose soon because you have to know how to look into the wiring system before drawing any conclusions.
But if there is a short circuit in the wiring or the connection is bad, you can easily fix it with a car mechanic’s help.
Fuse Malfunction
Before you move on to knowing what to do if your windshield wipers won’t turn off, know about this last reason that can cause such problems in your car windshield! Before you face a bad wiper motor, it is more likely that you will experience a blown-up fuse. It is more like a pre-warning before a wiper motor starts malfunctioning.
The fuse is considered to be the wiper motor’s weak spot; thus, before the problem starts in the motor, it has to go through the fuse first. And it is evident that if there is a problem with the fuse, it will eventually lead to the malfunction of the entire motor system causing the wipes to keep running automatically.
This mostly happens when the wiper motor is overloaded, so try to keep the load balanced while you use the motor frequently!
