Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shock.
Ensure the vehicle is parked on a level surface with the ignition off.

2. Check and Replace the Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Identify the wiper fuse using the diagram on the fuse box lid.
Remove the fuse using a fuse puller or pliers and inspect it for continuity.
If blown, replace it with a fuse of the same amperage.

3. Inspect and Replace the Wiper Motor

Remove the wiper arms by loosening the nuts at their bases with a socket wrench.
Carefully pull the wiper arms off the splined shaft.
Disconnect the electrical connector from the wiper motor.
Remove the mounting bolts securing the wiper motor to the vehicle.
Replace with a new wiper motor, ensuring it is aligned correctly when re-installing.

4. Test the Wiper Linkage

After removing the wiper motor, inspect the wiper linkage for any signs of wear or breakage.
If damaged, replace the wiper linkage assembly.
Reinstall the wiper motor and ensure that the linkage moves freely.

5. Reassemble and Test

Reattach the wiper arms to the splined shaft and secure with the nuts.
Reconnect the negative battery terminal.
Test the wipers by activating them to ensure they function correctly.
