1. Check the Wiper Blades

a. Visual Inspection:

- Inspect the wiper blades for any visible damage, such as cracks, tears, or glazing. Glazing occurs when the rubber surface becomes hardened and less effective.

- Check the rubber edge for smooth and even contact with the windshield. Any unevenness or notches can cause skipping or chattering.

b. Cleaning:

- Wipe away any dirt, debris, or grease from the wiper blades using a damp cloth or mild detergent.

- Avoid using harsh chemicals or abrasive cleaners that can damage the rubber.

2. Inspect the Wiper Motor

a. Check Connections:

- Ensure that the electrical connections to the wiper motor are secure and free of corrosion.

- Loose or corroded connections can lead to intermittent operation or reduced power.

b. Listen for Unusual Noises:

- Start the engine and activate the wipers. Listen for any unusual noises, such as grinding, squealing, or clicking.

- Persistent noises may indicate a problem with the motor or its components.

3. Examine the Wiper Linkage

a. Inspection:

- Check the wiper linkage for any loose or worn components, such as pins, ball joints, or arms.

- Loose or damaged linkages can cause the wipers to skip or move erratically.

b. Lubrication:

- If the linkage appears dry or stiff, apply a small amount of lithium grease or a dedicated wiper linkage lubricant.

- Lubrication will reduce friction and improve the smooth operation of the system.

4. Check the Windshield

a. Clean the Windshield:

- A dirty or greasy windshield can prevent the wiper blades from making proper contact and cause skipping or chattering.

- Clean the windshield thoroughly with a mild glass cleaner and a microfiber cloth.

b. Inspect the Windshield for Damage:

- Look for any chips, cracks, or scratches on the windshield that may interfere with the wiper blades' movement.

- Damage to the windshield can create uneven surfaces that cause the blades to skip or stutter.

5. Other Possible Causes

a. Faulty Wiper Switch:

- A faulty wiper switch can send incorrect signals to the wiper motor, causing inconsistent or erratic operation.

- Check the switch for any signs of damage or corrosion.

b. Relay or Fuse Issue:

- The wiper system relies on relays or fuses to control power flow.

- A blown fuse or a faulty relay can interrupt power supply to the wiper motor, affecting its operation.

6. Professional Diagnosis and Repair

If the wiper problems persist after following the above steps, it is recommended to take your vehicle to a qualified mechanic for professional diagnosis and repair.

- The mechanic can conduct a more thorough inspection and identify any underlying issues that may require specialized tools or expertise to resolve.

- They can also check for any potential electrical faults or component failures that require replacement or repair.
