Solution

1. Preparation

Ensure the vehicle is parked on a level surface.
Disconnect the negative terminal of the battery to prevent electrical shock.

2. Inspect and Replace Wiper Fuse

Locate the fuse box (typically under the dashboard or in the engine compartment).
Identify the wiper fuse using the diagram on the fuse box cover.
Remove the fuse with a fuse puller or pliers.
Inspect the fuse for continuity; replace it if it is blown (use the same amperage as specified).

3. Test Wiper Motor

Reconnect the battery temporarily.
Disconnect the wiper motor connector.
Using a multimeter, check for voltage at the motor connector while activating the wiper switch.
If voltage is present but the motor does not operate, replace the wiper motor.

4. Inspect Wiper Relay

Locate the relay associated with the wiper system (consult the vehicle’s service manual for exact location).
Remove the relay and visually inspect it for damage.
Replace the relay if it appears faulty or swap it with a similar relay to test.

5. Reassemble and Test

Reconnect all connectors and ensure everything is secure.
Reconnect the negative battery terminal.
Test the wipers by engaging the control lever.
