Solution

1. Preparation

Gather tools: socket set, multimeter, flathead screwdriver, and a torque wrench.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Identify the wiper fuse using the fuse box diagram.
Remove the fuse using a fuse puller or pliers.
Inspect the fuse for continuity; replace if blown with a new fuse of the same amperage.

3. Test and Replace Wiper Motor

If the fuse is intact, reconnect the battery and activate the wipers.
If no movement is observed, disconnect the wiper motor connector.
Using a multimeter, check for voltage at the motor connector while operating the wiper switch.
If voltage is present but the motor does not operate, remove the motor by unscrewing it from its mount.
Replace the wiper motor with a new one, ensuring it is seated correctly.
Reattach the electrical connector and secure the motor with screws.

4. Inspect and Repair Wiper Linkage

If the wipers are still not functioning properly, remove the wiper arms by unscrewing the retaining nuts.
Carefully lift the wiper arms off the splines.
Inspect the linkage for any signs of damage or disconnection.
If damaged, replace the wiper linkage assembly. If it is disconnected, reattach it and ensure all components are secure.

5. Reassemble and Test

Reinstall the wiper arms by aligning them correctly on the splines.
Tighten the retaining nuts to the manufacturer’s specification (usually around 15-20 Nm).
Reconnect the battery terminal and test the wipers in all modes (intermittent, low, and high speeds).
