Solution

1. Preparation

Gather tools: multimeter, socket set, flathead screwdriver, and replacement fuse/relay if needed.
Disconnect the negative battery terminal to ensure safety during repairs.

2. Inspect and Replace Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Remove the cover and find the wiper fuse (refer to the diagram on the fuse box cover).
Use a fuse puller or needle-nose pliers to remove the fuse.
Inspect the fuse for continuity; if blown, replace it with a fuse of the same amperage.

3. Test and Replace Wiper Relay

Locate the wiper relay in the fuse box.
Remove the relay by pulling it straight out.
Check the relay for any signs of damage or corrosion.
If necessary, replace it with a new relay that matches the specifications.

4. Test Wiper Motor

Locate the wiper motor, usually found at the base of the windshield.
Disconnect the electrical connector from the wiper motor.
Using the multimeter, apply power directly to the motor terminals to check for operation.
If the motor does not function, replace it with a new wiper motor.

5. Reassemble and Test

Reconnect all electrical connectors and replace any covers removed during the process.
Reconnect the negative battery terminal.
Test the wipers to ensure proper function.
