Check the wiper fuse in the fuse box.

Inspect the wiper motor and linkage for any damage or corrosion.

Test the wiper switch by manually activating the wiper relay.

2. Intermittent Wipers Not Working:

Ensure the intermittent switch is activated.

Check the wiper time delay relay for proper operation.

3. Wipers Operating Erratically:

Inspect the wiper switch for any loose connections or damaged contacts.

Check the wiper motor and linkage for any obstructions or binding.

Replacement and Maintenance

Replacing a TJ wiper switch is relatively straightforward. It typically involves removing the steering column cover and disconnecting the electrical connector. Ensure the replacement switch matches the original specifications for proper functionality.

To maintain optimal performance of the wiper switch, keep the switch and surrounding area clean. Avoid spilling liquids on the switch and inspect the electrical connections regularly for any signs of corrosion.

Additional Tips

For improved wiper performance in heavy rain, consider using wiper blades with a graphite coating.

If the wipers leave streaks or smudges, try cleaning the windshield with a glass cleaner and a microfiber towel.

Avoid overusing the wipers in dry conditions as it may damage the wiper blades and motor.

Conclusion

The TJ wiper switch plays a vital role in ensuring clear visibility during inclement weather. By understanding its functions, troubleshooting potential issues, and following proper maintenance practices, drivers can maintain a safe and comfortable driving experience.
