Solution

1. Preparation

Gather tools and parts.
Disconnect the negative battery terminal to prevent electrical shock.

2. Check and Replace the Wiper Fuse

Locate the fuse box, typically found in the glove compartment or under the dashboard.
Identify the fuse responsible for the wiper system using the fuse diagram.
Remove the fuse using a fuse puller.
Inspect the fuse; if blown, replace it with a new fuse of the same amperage.
Reconnect the battery and test the wipers.

3. Inspect and Test the Wiper Motor

Locate the wiper motor, usually found under the cowl cover.
Disconnect the electrical connector from the wiper motor.
Use a multimeter to test for voltage at the connector while the wiper switch is activated.
If no voltage is present, trace back to the switch for further testing.
If voltage is present, replace the wiper motor.

4. Inspect the Wiper Linkage

Remove the wiper arms using a puller tool.
Remove the cowl cover to access the wiper linkage.
Visually inspect the linkage for any broken or disconnected components.
If damaged, replace the wiper linkage assembly.

5. Test the Washer Pump

Locate the washer fluid reservoir and pump.
Disconnect the pump connector.
Use a multimeter to check for voltage at the connector while pressing the washer switch.
If voltage is present but the pump does not operate, replace the washer pump.
