Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the vehicle's battery to ensure safety.
Tools Required: Socket set, multimeter, wire brush, or contact cleaner.

2. Inspect and Replace the Wiper Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Remove the fuse for the windshield wipers using a fuse puller.
Inspect the fuse for a broken filament. If broken, replace it with a fuse of the same amperage.
Reinstall the fuse and reconnect the battery.

3. Test and Replace the Wiper Motor

If the fuse is intact, locate the wiper motor (usually under the cowl near the windshield).
Disconnect the wiring harness from the motor.
Using a multimeter, test for voltage at the motor terminals while engaging the wiper switch. If voltage is present but the motor does not operate, replace the wiper motor.
To replace, remove the mounting bolts and disconnect the motor from the linkage. Install the new motor by reversing the procedure.

4. Inspect the Wiper Linkage

If the wiper motor is operational, check the wiper linkage for wear or damage.
Remove any obstructions and lubricate the linkage if necessary. Tighten any loose bolts.

5. Reassemble and Test

Reconnect all components, ensuring secure connections.
Reinstall any covers or panels that were removed during the inspection.
Reconnect the battery and test the wipers for proper operation.
