Solution

1. Preparation

Gather tools: socket set, multimeter, wire cutters, and electrical connectors.
Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Inspect and Replace the Fuse

Locate the fuse box, usually found under the dashboard or in the engine compartment.
Remove the cover and identify the windshield wiper fuse using the diagram on the fuse box cover.
Remove the fuse and check for continuity using a multimeter. If blown, replace with a fuse of the same amperage.

3. Test and Replace the Relay

Locate the wiper relay in the fuse box.
Remove the relay and test it by swapping it with a similar relay (ensure that it has the same specifications).
If function is restored with the swapped relay, replace the faulty relay.

4. Inspect Wiring and Connectors

Visually check the wiring harness leading to the wiper motor for any cuts, frays, or corrosion.
Clean any corroded connectors using electrical contact cleaner and reconnect securely.
If damaged wiring is found, repair or replace as necessary.

5. Test the Wiper Motor

If previous steps do not resolve the issue, access the wiper motor, typically located under the cowl panel.
Disconnect the motor’s electrical connector.
Using jumper wires, connect the motor directly to the battery to see if it operates. If it doesn't, the motor likely needs replacement.
