Solution

1. Preparation

Gather tools: socket set, multimeter, wiring diagram, and safety gloves.
Disconnect the negative battery terminal to ensure safety.

2. Inspect and Replace the Wiper Control Switch

Remove the steering column cover using a socket set.
Disconnect the wiring harness from the wiper control switch.
Test the switch for continuity using a multimeter.
If faulty, replace with a new switch, reassemble the steering column, and reconnect the battery.

3. Check and Replace the Wiper Fuse

Locate the fuse box (refer to the owner’s manual for specific location).
Remove the wiper fuse and inspect for continuity with a multimeter.
Replace with a fuse of the same amperage if blown.
Reinstall the fuse and check for functionality.

4. Test and Replace the Wiper Motor (if necessary)

Remove the wiper arms using a puller tool if needed.
Disconnect the wiper motor connector.
Apply direct power to the motor terminals (use a battery or jumper cables) to see if it operates.
If the motor does not function, replace it with a new motor, reconnect wiring, and reinstall wiper arms.

5. Inspect and Repair Wiper Linkage

Remove any covers or panels obstructing access to the wiper linkage.
Inspect the linkage for any binding or damaged components.
Lubricate any binding points and replace any damaged parts as necessary.
Reassemble all components and test wipers.
