Solution

1. Preparation

Gather necessary tools.
Park the vehicle on a flat surface and set the parking brake.
Disconnect the battery to prevent electrical shock.

2. Check and Replace Fuse

Locate the fuse box, typically under the dashboard or in the engine compartment.
Identify the wiper fuse using the diagram on the fuse box cover.
Remove the fuse using a fuse puller and check for continuity with a multimeter.
If blown, replace it with a new fuse of the same amperage.

3. Test the Wiper Motor

Reconnect the battery.
Turn on the wiper switch.
Use a multimeter to check for voltage at the wiper motor connector.
If voltage is present but the motor does not operate, the motor may need replacement.

4. Inspect and Repair Wiper Linkage

Remove the wiper arms by loosening the nut securing them to the motor shaft.
Lift the wiper arms off and set them aside.
Inspect the linkage for any loose or disconnected joints.
Reconnect or replace any damaged components in the linkage assembly.

5. Replace Wiper Motor (if necessary)

Disconnect the battery again.
Remove the screws securing the wiper motor to the assembly.
Detach the wiring harness from the motor.
Install the new motor by reversing the removal steps.
Reconnect the battery and test the wipers.
