Have you noticed your windshield wipers won’t turn off? There are a couple of different possible causes for this. Find out some of the most common problems that might cause this, and how to turn off windshield wipers below.
If you’re not a big car expert, it can be hard to keep track of everything that’s going on inside modern vehicles. This even includes windshield wipers which may fail for various reasons.
If your car’s wipers do not stop regardless of where the switch controlling the wipers is located, it could be due to several reasons. Find out the reasons behind this below to take the proper steps to fix it.
Why Won’t My Windshield Wipers Turn Off
A loose wire or bad connection is a major reason why the windshield wipers won’t turn off after you have turned it off. It could also be because of a faulty relay, broken control, or a bad park switch. If this happens, your windshield wipers won’t receive the proper command and won’t turn off.
How Does the Wiper System Work?
Modern windshield washer assemblies consist of several components that include the wiper switch with an electric motor for the windshield wipers, linkage assemblies, arms for the wipers, and a washer fluid tank.
If you turn the wipers on, an electric motor moves a rod in a circular motion, turning the wiper blades from one side of your car to another.
This type of mechanism is called a linkage system and transmits power to swivel the windshield wiper blades from left to right across your windshield.
When the wipers are switched off, it activates the park mechanism on the motor that halts power from the linkage and arms after the wipers are back to their lower position.

How to Turn Off Windshield Wipers
To turn off your windshield wipers, move the wiper stalk located at the right-hand side of the steering wheel back into its original position. You should hear a clicking sound as you move it. If all mechanical parts are functioning properly, the windshield wiper will turn off.
Windshield Wipers Won’t Turn Off (Causes)
The following are several reasons why your windshield wipers may not turn off after you have turned them off.
1. Broken Windshield Wiper Control
One of the main reason why your windshield wipers won’t turn off is a broken wiper control.
The switch used to control the motor of your windshield wiper is often used and may wear out sometimes, causing it to continue operating regardless of your setting.
This is a safety concern for drivers who might not be able to pay attention to the road whenever the wipers are on.
2. Faulty Park Switch
A faulty park switch is another reason why your windshield wipers won’t turn off.
The motor within the wiper is an electrical park switch used to turn the wipers off when you have parked your car.
If this component malfunctions, an electrical charge can run through your windshield’s washers, and they may not be able to turn off like they normally would.
Furthermore, because there’s energy running through them, even though your vehicle may be turned off, power will still continuously flow from the blades, which causes it to burn a lot of battery life.
3. Bad Wiring
Loose connections or bad wiring is a significant reason why your windshield wipers won’t turn off. When your windshield wipers are off, your wipers may operate due to a loose wire or a bad connection.
An experienced professional can easily determine what might be wrong with the wiring using the right diagnostic tools.
4. Faulty Relay
A faulty relay is another reason why windshield wipers won’t turn off. Each pair of wipers comes with a relay that enables the wiper to ‘park’ in place or move without doing the work.
Automotive relays are like plastic containers which plug into an exact position on a panel under the hood, close to other switches and relays that are already installed.
If you have a bad relay, you may have faulty windshield wipers that park but won’t turn off, or they could park and stay put when you think they’ve been turned off.
You may need to replace the wiper relay to be able to fix the problem. A wiper relay costs approximately below $20.

How to Maintain Windshield Wipers
- Always Turn Off Your Wipers Before Turning off Your Car.
- Don’t Use Your Wipers With Dirt Still on Your Glass When Your Windshield Is Dirty.
- Remove Any Pine Needles or Leaves Before Turning on the Windshield Wipers.
- Use Sandpaper to Clean Your Wiper Blades Twice a Year.
- Don’t Use Your Windshield Wipers in Freezing Rain
1. Always Turn Off Your Wipers Before Turning off Your Car.
By failing to do this, the chances are that they will start up again as soon as the car is restarted, and this can cause harm to the blades of your wipers resulting in irrelevant wear and tear to the blades, making your wipers ineffective.
2. Don’t Use Your Wipers With Dirt Still on Your Glass When Your Windshield Is Dirty.
Doing this makes it difficult for the wiper blades to effectively clear the windshield and clean it of wetness without being hindered by all that debris leftover from previous wiper passes or by other particles floating around on the road!
If you find yourself in such a scenario, use your washer fluid to remove any particles clinging to the windshield before wiping it clean using a dry cloth.
Otherwise, there’s a chance that debris could be picked up by your blades and lead them to become ineffective over time.
3. Remove Any Pine Needles or Leaves Before Turning on the Windshield Wipers.
Operating the windshield wipers while they pick up debris can result in problems later.
For example, if a leaf gets caught between two blades of the wiper and becomes trapped, water will pass between the two metal parts and eventually damage your windshield wipers and even your car.
To ensure that you take care of yourself and your car, try switching on the defroster and letting it run for at least one minute before attempting to clear your windshield.
This will clear most debris from the glass allowing you to wipe it away easily.
4. Use Sandpaper to Clean Your Wiper Blades Twice a Year.
In time, the gradual accumulation of debris and dirt on your wiper blades may cause the blades to lose contact with the windshield.
Every two years, cleaning them using sandpaper will eliminate any build-up and restore the blade’s ability to clean and wipe the windshield.
It’s important to clean your windshield wipers at least two times a year. Both natural accumulation of debris and dirt and environmental factors can result in the blades losing contact with the windshield.
Cleansing the blades with sandpaper on a two-year cycle will keep the blades’ ability intact, keeping them in contact with the glass at all times.
5. Don’t Use Your Windshield Wipers in Freezing Rain
The best thing to do instead is to take advantage of the defroster or use a scraper. Whenever your wiper blades become wet, sometimes they can get frozen onto the window, preventing you from seeing ahead.
Also, similar to other types of debris, ice and water can get into the gap between the wiper blade and windshield, which makes them less efficient.
So when there is the possibility of a snowy climate, and you’re going to leave your car outside, To prevent a “freezing” wiper from ruining the rubber – it’s critical that you adjust the wipers on your windshield into an upwards position so as not to cause any permanent damages like scratches, cracks or gouges, etc.
Frequently Asked Questions – Windshield Wipers Won’t Turn Off
Why Do My Windshield Wipers Not Turn Off?
If you notice your vehicle’s wipers are not turning off when you switch the car off, check to ensure that your park switch is functioning properly. If it’s not set to “park,” the wipers could be getting stuck in gear and will not turn off – even when the car is off! If that doesn’t solve the problem, make sure all of the connections on your wiring harnesses aren’t loose.
How Do You Turn on Front Windshield Wipers?
To use the wiper blades, hold down the stalk located to the right of your steering column. Then, slide the stalk downward in one position for delayed interval speed. The new motor carriage on modern cars makes it extremely easy to operate so that you can choose a speed that works for you.
Where Is the Windshield Wiper Switch Located?
The windshield wiper switch is located behind the steering wheel. It is a lever that controls how fast the blades spin around. When you turn the knob for this lever, it’s connected to a motor that spins at whatever speed you’ve selected. So if the blades aren’t stopping when you let them go after cleaning your windshield, it could be that the motor isn’t responding correctly, or it could be because of a switch not receiving enough electricity.
What Is a Wiper Park Switch?
The wipers’ park switch permits the wiper motor to stop when the wipers are placed in their “park” position, which is on the bottom part of the windshield.
