What to Do If Your Car Wipers Make Noise: Troubleshooting and Solutions

1. Check the wiper blades. The most common cause of noisy wipers is worn or damaged wiper blades. Over time, the rubber on the blades can become cracked or hardened, which can cause them to skip or chatter across the windshield. To check the wiper blades, simply lift them up and inspect them for any signs of damage. If the blades are worn, they should be replaced.

2. Clean the windshield. Another common cause of noisy wipers is a dirty windshield. If the windshield is covered in dirt, dust, or debris, it can cause the wipers to skip or chatter. To clean the windshield, simply use a glass cleaner and a microfiber cloth.

3. Adjust the wiper arms. If the wiper blades and windshield are both clean, but the wipers are still making noise, the wiper arms may need to be adjusted. The wiper arms should be positioned so that the blades make firm contact with the windshield. To adjust the wiper arms, simply loosen the bolts that hold them in place and move them to the desired position.

4. Check the wiper motor. If the wiper blades, windshield, and wiper arms are all in good condition, but the wipers are still making noise, the wiper motor may need to be replaced. The wiper motor is responsible for powering the wipers, and if it is failing, it can cause the wipers to make a variety of noises. To check the wiper motor, simply listen for any unusual noises when the wipers are turned on. If the wiper motor is making a loud noise, it should be replaced.

5. Have the wipers inspected by a mechanic. If you have tried all of the above steps and the wipers are still making noise, it is best to have the wipers inspected by a mechanic. A mechanic will be able to diagnose the problem and recommend the best course of action.

1. Determine the Source of the Noise

Loose nuts or bolts: Inspect the wiper assembly for any loose parts. Tighten any loose nuts or bolts using a wrench or pliers.

Worn or damaged wiper blades: Check for any tears, cracks, or deformation in the wiper blades. Replace worn or damaged blades with new ones.

Clogged or rusted wiper arms: Remove any debris or rust from the wiper arms using a damp cloth and cleaning solution. Apply a lubricant to the arms to ensure smooth movement.

Dry or damaged windshield: Wash the windshield thoroughly to remove any dirt or debris. Apply a windshield washer fluid to keep the glass lubricated.

2. Lubricate the Wiper Assembly

Silicone spray: Apply silicone spray to the pivot points and hinges of the wiper assembly. This will reduce friction and eliminate squealing or squeaking noises.

Petroleum jelly: Apply a small amount of petroleum jelly to the wiper arms and blades. This will create a temporary lubricant and reduce noise.

3. Adjust the Wiper Pressure

Bend the wiper arm: Gently bend the wiper arm down slightly to increase the pressure of the blades against the windshield. This can improve the removal of debris and reduce noise.

Adjust the tension spring: Locate the tension spring that holds the wiper arm against the windshield. Tighten the spring to increase pressure.

4. Replace the Wiper Linkage

Loose or damaged linkage: If the wiper linkage becomes loose or damaged, it can cause noise. Replace the entire linkage with a new one.

Disconnect the linkage: Disconnect the wiper linkage from the motor and inspect it for any damage or loose connections. Reattach the linkage securely.

5. Check the Wiper Motor

Burnt-out motor: If the wiper motor burns out, it will make a clicking or grinding noise. Replace the motor with a new one.

Loose or corroded connections: Check for any loose or corroded connections between the wiper motor and the electrical system. Tighten or clean connections as necessary.

6. Troubleshooting Electrical Issues

Check the fuse: Locate the fuse that powers the wiper motor and check if it has blown. Replace the fuse if necessary.

Test the wiring: Use a multimeter to test the continuity of the wiring harness that connects the wiper motor to the electrical system. Repair any damaged or broken wires.

Check the relay: Locate the relay that controls the wiper motor and check if it is functioning properly. Replace the relay if it fails to operate correctly.
