Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface with the ignition off.
Disconnect the battery to prevent electrical shock.

2. Check Wiper Control Switch

Remove the steering column cover using a screwdriver.
Locate the wiper control switch and inspect for damage or disconnection.
If necessary, replace the wiper control switch.

3. Inspect Wiper Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Identify the wiper fuse using the fuse diagram.
Remove the fuse and check for continuity using a multimeter.
- If blown, replace with a fuse of the same amperage.

4. Test Wiper Motor

Reconnect the battery.
Locate the wiper motor, typically found at the base of the windshield.
Disconnect the wiring harness from the motor.
Use a multimeter to measure voltage at the connector when the wiper switch is activated.
- If there is no voltage, check the relay and wiring.
If voltage is present, connect a jump wire to the motor to test if it operates directly.

5. Inspect Wiring and Relay

Examine the wiring harness for frayed or damaged wires.
If necessary, repair or replace damaged wiring.
Test the wiper relay by swapping it with a similar relay in the fuse box (if applicable) to see if the wipers function.
