Solution

1. Preparation

Gather tools: screwdriver set, multimeter, OBD-II scanner, and replacement parts as needed.
Disconnect the negative terminal of the battery to ensure safety while working on electrical components.

2. Check and Replace the Wiper Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Remove the cover and identify the windshield wiper fuse using the diagram on the cover or the owner’s manual.
Inspect the fuse visually; if it is blown, replace it with a new fuse of the same amperage.
Reconnect the battery and test the wipers again.

3. Inspect and Repair the Wiper Switch

Remove the steering column cover using a screwdriver.
Disconnect the wiring connector from the wiper switch.
Use a multimeter to check for continuity in the switch. If defective, replace with a new switch.
Reassemble the steering column cover.

4. Test and Replace the Wiper Motor

Locate the wiper motor, typically found under the cowl panel at the base of the windshield.
Disconnect the electrical connector from the motor.
Using a multimeter, check for voltage at the connector while activating the wiper switch. If there is voltage but the motor does not operate, proceed to replace the motor.
If no voltage is present, trace wiring back to the switch and relay for issues.
If replacing, install the new motor by reversing the removal process and secure it with bolts.

5. Verify Wiper Relay Function

Locate the wiper relay in the fuse box.
Remove the relay and test it with a multimeter for continuity.
If faulty, replace it with a new relay.
