Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked safely with the engine off.
Disconnect the battery to prevent any electrical shorts.

2. Inspect and Replace Wiper Fuse

Locate the fuse box, usually found under the dashboard or in the engine compartment.
Remove the cover and locate the wiper fuse using the diagram on the fuse box cover.
If the fuse is blown, replace it with one of the same amperage (usually 10A or 15A).
Reconnect the battery.

3. Test and Replace the Wiper Motor

If the wipers still do not function, test the motor.
Disconnect the motor's electrical connector.
Use a multimeter to check for voltage at the connector while the wiper switch is activated.
If voltage is present but the motor does not operate, remove the motor by unscrewing it from its mounting points.
Replace the motor with a new one if it is determined to be faulty.

4. Check and Repair Wiring and Connections

Inspect all wiring leading to the wiper motor for frays or breaks.
Repair or replace damaged wiring as necessary.
Ensure all connectors are seated properly and are not corroded.

5. Inspect Wiper Linkage

If the motor operates but the wipers do not move, the linkage may be at fault.
Remove the wiper arms by loosening the retaining nuts.
Inspect the linkage for wear or binding.
Lubricate if necessary, or replace the linkage if damaged.
