These queries line up immediately in such circumstances. 

We’re about to get into all those queries and answer your most commonly asked questions on the context. 

This article is all you need if you are struggling with a non-stopping windshield wiper and don’t know how to get it to behave. 

Let us take you through all you need to know about identifying and resolving the issue when the windshield wiper won’t turn off in your vehicle. 

How Can I Turn Off Windshield Wipers? 

Turning off windshield wipers is a no-brainer. 

Get to the control stalk and turn the dial back to the “off” position. 

If you used a lever for controlling, put the lever back in the off position. 

Once done, now you will see your windshield wipers slowly coming to rest and completely stopping working.  

Windshield Wiper Won’t Turn Off – Why? 

If your windshield wiper does not turn off even though you have tried to turn them off several times, there must be a malfunction somewhere in the wiper system. 

The cause isn’t a single one. There could be multiple reasons for this occurrence. 

Do not drive when your windshield wipers won’t turn off unless you want a pleasant accident. 

Yes, they could obstruct the driver’s view and be a potential hindrance. 

Back to the investigation, what causes windshield wipers to run non-stop and go bananas? 

Let us look at the various causes that could be the culprit. 

• Short Circuits 

Wipers run on its wiring system. 

When this wiring system is vandalized by external elements, it could sometimes result in short circuits (especially when water makes its way through since it is not that hard – rain, snow, etc.) 

When a circuit is short, the current flow will lose its intended pathways and start acting up by travelling non-stop and when not needed. 

This might be the cause of why your windshield wipers won’t turn off. Do not startle next time, and look for a ghost when your wipers start running on their own! It’s the short circuits. 

• Damaged Park Switch 

The park switch is responsible for bringing the windshield wipers to rest after the operation. 

However, it works on slow progress. Once you’ve turned off the wipers, the park switch will decelerate the wiper motion and slowly bring it to rest. 

This intended ordinary function will be messed up if the park switch is problematic. 

When the switch is worn out, faulty or damaged, it wouldn’t be able to perform its function properly, which can result in windshield wipers not turning off. 

• Faulty Motor Relay Switch 

The relay switch allows and prevents current flow into the wipers. 

To put it more simply, it relays the electricity as needed when you turn the wiper switch on and off. 

If the relay switch is faulty or damaged, the current relaying will get messed up. 

The outcome? Crazy windshield wipers! 

• Defective Sensors 

Modern vehicles have a sensing system that senses rain and automatically turns on the windshield wipers. 

While it sounds great, sometimes it can get a bit annoying. 

Even when there is no rain and your sensors sense wetness, they will turn on the wipers. 

Suppose the sensors become faulty; in that case, it is a nightmare. 

It will keep waking up the wipers and putting them to sleep, sometimes leaving them on the run. 

• Wiring Issues

A perfectly set wiring system will ensure seamless operation. 

What happens if there are problems with the wiring? In that case, you will also have to expect problems in the operations. 

Thus, another reason for windshield wipers on non-stop motion is bad wiring.

The operation control switch should work in good health. 

How can you confirm it?

If it doesn’t, it’s time to replace the old control switch with a new one. 

You can do it by yourself or seek the help of a professional. 

• Seal the Leakages 

Any external damage that might/will influence the internal operation of the windshield wipers should be shoved off. 

Such as? Holes, leakages, scratches, etc. 

Identify all such external weak areas and fix them.
