The wiper blades sweep away rain, snow, and other debris to ensure clear visibility for the driver.

3. Maintenance:

Regular maintenance of the Toyota Corona T190 Sedan car wiper system is essential for optimal performance and longevity. Key maintenance tasks include:

 Blade replacement: Wiper blades should be replaced every six months to a year, or when they become worn or damaged. Ensure the replacement blades are the correct size and type for your vehicle.
 Wiper arm inspection: Check the wiper arms for cracks, corrosion, or loose connections. If any damage is found, have it repaired or replaced by a qualified mechanic.
 Wiper motor lubrication: The wiper motor should be lubricated every two to three years to minimize wear and extend its lifespan. Use a silicone-based lubricant specifically designed for automotive use.
 Washer fluid check and refill: Top up the washer fluid reservoir as needed to ensure a continuous supply of fluid for the windshield sprayer. Use a washer fluid solution that is suitable for your climate and vehicle.

4. Troubleshooting:

If the Toyota Corona T190 Sedan car wiper system is not functioning properly, it may be due to one of the following issues:

 No power: Check the wiper fuse, which is usually located in the fuse box under the dashboard. Replace the fuse if it is blown.
 Faulty wiper motor: The wiper motor may have failed. Have it tested by a mechanic and replaced if necessary.
 Damaged wiring: Inspect the wiring harness that connects the wiper motor to the control switch. Look for any loose connections or broken wires.
 Clogged washer fluid nozzles: The washer fluid nozzles may be clogged with dirt or debris. Clean them with a small needle or compressed air.
 Frozen wiper blades: In freezing temperatures, the wiper blades may become stuck to the windshield. Do not force them to move. Instead, use a de-icer to melt the ice and free the blades.
