Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the ignition is turned off.

2. Check and Replace Fuse

Tools Required: Fuse puller or needle-nose pliers
Open the fuse box cover located under the dashboard or in the engine bay.
Locate the windshield wiper fuse using the diagram on the cover.
Remove the fuse and inspect it for a break in the filament.
If blown, replace it with a fuse of the same amperage.

3. Inspect and Test the Wiper Motor

Tools Required: Multimeter, socket set, screwdriver
Disconnect the wiring harness from the wiper motor.
Using a multimeter, check for voltage at the motor connector while activating the wiper switch.
If voltage is present but the motor does not operate, remove the motor from the vehicle.
- Remove the motor mounting bolts.
- Disconnect any remaining wiring.
Bench test the motor by connecting it directly to a power source (positive and negative terminals) to see if it operates.

4. Replace Wiper Motor (if necessary)

If the motor does not operate during the bench test, replace it with a new wiper motor.
Tools Required: Socket set, torque wrench
Install the new wiper motor by reversing the removal steps.
Torque the mounting bolts to manufacturer specifications (typically around 8-10 Nm).
Reconnect the wiring harness securely.

5. Reassemble and Test

Reinstall any covers or components removed during the repair.
Turn on the ignition and test the wipers for proper operation.
