This article will provide a comprehensive guide on troubleshooting windshield wipers that do not work. We will cover the various causes of wiper malfunction and offer step-by-step instructions on how to diagnose and fix the problem. By following the advice in this article, you can ensure that your windshield wipers are always in good working condition, providing you with a clear view of the road ahead.
Before you start troubleshooting, it is important to check the wiper fuse and relay. A blown fuse or a faulty relay can prevent the wipers from working properly. Once you have checked the fuse and relay, you can move on to the more specific troubleshooting steps outlined in this article.
How to troubleshoot windshield wipers
The first step in troubleshooting windshield wipers is to check the fuse. If the fuse is blown, it will need to be replaced. The fuse box is typically located under the dashboard or in the engine compartment. Once the fuse has been replaced, try turning on the windshield wipers again. If they still don't work, the next step is to check the wiper motor.
The wiper motor is located under the hood, near the base of the windshield. To check the wiper motor, disconnect the electrical connector and then use a multimeter to test for continuity. If there is no continuity, the wiper motor will need to be replaced.
Windshield wiper troubleshooting guide
Windshield wipers are an essential safety feature of your car, and it's important to keep them in good working order. If your windshield wipers aren't working properly, there are a few things you can check before taking your car to the mechanic.
First, check the fuse for the windshield wipers. If the fuse is blown, replace it. Next, check the wiper blades. If the blades are worn or damaged, replace them. Finally, check the wiper motor. If the motor is not working, you may need to replace it.
Why are my windshield wipers not working
Check the fuse
If your windshield wipers aren't working, one of the first things you should check is the fuse. A blown fuse can prevent power from reaching the wiper motor, which will cause the wipers to stop working. To check the fuse, you'll need to locate the fuse box in your vehicle. Once you've found the fuse box, open it up and look for the fuse that is labeled "windshield wipers." If the fuse is blown, you'll need to replace it with a new one of the same amperage.
Once you've replaced the fuse, try turning on the windshield wipers again. If they still don't work, there may be another problem with the wiper system. You can try checking the wiper motor, the wiper linkage, or the wiper switch. If you're not comfortable working on your vehicle, you can take it to a mechanic to have it diagnosed and repaired.
Here are some tips for checking the fuse:
1. Make sure that the vehicle is turned off and the key is removed from the ignition.
2. Locate the fuse box in your vehicle. It is usually located under the dashboard or under the hood.
3. Open the fuse box and look for the fuse that is labeled "windshield wipers." It may be a different color than the other fuses.
4. If the fuse is blown, you will need to replace it with a new one of the same amperage.
5. Once you have replaced the fuse, try turning on the windshield wipers again. If they still don't work, there may be another problem with the wiper system.
Check the relay
The relay is a small electronic device responsible for completing the circuit that provides power to the windshield wiper motor. A bad relay can prevent the wipers from working, so it's important to check it if you're having trouble with your wipers.
To check the relay, you'll need to locate it in the fuse box. Once you've found the relay, use a multimeter to test its continuity. If the relay is bad, you'll need to replace it.
Inspect the wiper motor
The wiper motor is responsible for powering the windshield wipers. If the wiper motor is not working, the wipers will not be able to move. To inspect the wiper motor, you will need to remove the wiper blades and the wiper arms. Once the wiper arms are removed, you will be able to see the wiper motor. Check the motor for any signs of damage, such as cracks or leaks.
If you see any signs of damage, the wiper motor will need to be replaced. You can also test the wiper motor by applying power to it directly. If the motor does not run, it will need to be replaced.
Inspecting the wiper motor is a simple task that can be completed in a few minutes. By following these steps, you can ensure that your windshield wipers are working properly.
Examine the wiper blades
Examine the wiper blades closely for any signs of damage or wear. Cracks, tears, or missing pieces can all reduce the effectiveness of the wipers and lead to streaking or smearing on the windshield. If the blades are worn or damaged, they should be replaced.
You should also check the wiper arms and pivots for any signs of rust or corrosion. If the arms or pivots are damaged, they may not be able to move the blades properly, which can also lead to streaking or smearing.
Look at the wiper linkage
Examine the wiper linkage, which is a system of rods and joints that transmit motion from the wiper motor to the wiper arms, to ensure it's functioning properly.
If the linkage is damaged or disconnected, the wipers may not move or may only move erratically. Inspect the linkage for any signs of wear, corrosion, or breaks, and replace it if necessary.
Check the wiper switch
Test the wiper fluid
Check the wiper fluid reservoir to make sure it's full. If it's empty, fill it up with a mixture of water and wiper fluid. The water will help to keep the fluid from freezing in cold weather.
Once the reservoir is full, turn on the wipers and see if they're working properly. If they're not, there may be a problem with the wiper motor or the wiring.
If you're still having problems with your windshield wipers, you can take your car to a mechanic for further diagnosis.
Here are some additional tips for testing your wiper fluid:
- Make sure that the nozzles are not clogged.
- If you live in a cold climate, use a wiper fluid that is designed for cold weather.
- Replace your wiper blades every six months or so.
- If you're having problems with your windshield wipers, don't hesitate to take your car to a mechanic for further diagnosis.
Frequently Asked Questions
Are the wiper blades damaged?
Damaged wiper blades can cause streaks or skipping on your windshield. Inspect the blades for cracks, tears, or other damage. If they are damaged, they will need to be replaced.

Summary
If your windshield wipers aren't working, there are a few things you can check. First, make sure that the wiper switch is turned on. If it is, then check the fuses to see if they have blown. If the fuses are good, then the problem could be with the wiper motor or the wiring. You can try tapping on the wiper motor to see if it starts working. If it does, then the motor is probably just stuck. If tapping on the motor doesn't work, then you will need to check the wiring to see if it is damaged.
If you are not comfortable checking the wiring yourself, you can take your car to a mechanic to have it checked out. The mechanic will be able to diagnose the problem and fix it for you.
