Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, screwdrivers, and safety glasses.
Disconnect the vehicle battery to avoid electrical shock during repairs.

2. Inspect and Replace Fuse

Locate the fuse panel, typically found 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 and inspect it for continuity. Replace it if it is blown.
Reconnect the battery and test the wipers. If they work, the problem is resolved.

3. Test Wiper Switch

Remove the steering column cover using a screwdriver.
Disconnect the wiper switch connector and use a multimeter to check for continuity when the switch is activated.
If the switch is faulty, replace it with a new one by removing it from the steering column and installing the new switch.

4. Inspect Wiring and Connections

Visually inspect the wiring harness leading to the wiper motor for any signs of damage or corrosion.
Clean any corroded connectors with electrical contact cleaner and reassemble.

5. Test Wiper Motor

Disconnect the wiper motor connector.
Using a multimeter, check for voltage at the connector while activating the wiper switch.
If voltage is present but the motor does not operate, remove the motor from the vehicle and apply direct battery power to test its functionality.
If the motor fails to operate, replace it with a new wiper motor.

6. Inspect Wiper Linkage

Remove the wiper arms using a puller tool if necessary.
Remove the cover and inspect the wiper linkage for any broken or disconnected parts.
If damaged, replace the wiper linkage assembly.
