Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Inspect and Replace Fuse

Locate the fuse box, usually found under the dashboard or in the engine compartment.
Remove the fuse panel cover.
Identify the fuse for the windshield wipers using the diagram on the cover.
Check if the fuse is blown and replace it with a new fuse of the same amperage.

3. Test and Replace Wiper Motor

Reconnect the battery.
If the fuse was intact, apply 12V directly to the wiper motor using jumper wires to test its functionality.
If the motor does not activate, remove the wiper motor:
- Disconnect the wiring harness from the motor.
- Unbolt the motor from its mounting bracket.
- Replace with a new wiper motor if defective.

4. Inspect Wiper Linkage

With the wiper motor removed, check the wiper linkage for any signs of wear or disconnection.
Reattach or replace linkage components that may be damaged.

5. Reassemble and Test

Reinstall the wiper motor and secure it with bolts.
Reconnect the wiring harness.
Test the wipers in all modes (low, high, and intermittent) to ensure proper operation.
