Solution

1. Preparation

Gather necessary tools and safety equipment.
Disconnect the vehicle battery to ensure safety while working on electrical components.

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 located on the fuse box cover.
Remove the fuse using a fuse puller or pliers.
Inspect the fuse for continuity; if blown, replace it with a new fuse of the same amperage.

3. Test and Replace the Wiper Motor (if necessary)

Reconnect the battery and turn on the ignition.
Activate the wiper switch and check for voltage at the wiper motor connector using a multimeter.
If there is no voltage, the issue may be with the switch or wiring; otherwise, proceed to replace the motor.
To replace the motor:
- Remove the wiper arms by loosening the securing nuts with a socket set.
- Remove any covers concealing the wiper motor.
- Unscrew the motor mounting bolts and disconnect the wiring harness.
- Install the new wiper motor by reversing the removal steps and securing it with bolts.

4. Inspect and Repair Wiper Linkage

If the wiper motor is functional but wipers are still not working:
- Remove the wiper arms and the motor (if not already done).
- Inspect the linkage for any disconnects or wear.
- If damaged, replace the linkage assembly.
- Lubricate any moving parts and reassemble.
