Solution

1. Preparation

Gather tools: screwdriver set, multimeter, wire brush, electrical cleaner.
Ensure the vehicle is parked on a flat surface and the ignition is off.

2. Check and Replace Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Remove the wiper fuse using a fuse puller or pliers.
Inspect the fuse for continuity; if blown, replace it with a fuse of the same rating.

3. Inspect and Test Wiper Motor

Disconnect the wiper motor's electrical connector.
Use a multimeter to test for voltage at the connector while activating the wiper switch.
If no voltage is detected, investigate the wiring or switch further.
If voltage is present, connect the motor directly to the battery to check for functionality.

4. Check Wiper Linkage and Arm

Remove the wiper arms by loosening the retaining nuts using a socket set.
Inspect the linkage for any signs of wear or disconnection.
If the linkage is damaged, replace it accordingly.

5. Reassemble and Test

Reattach the wiper arms securely to the splines on the motor.
Reconnect any electrical connectors.
Test the wipers to ensure they operate correctly.
