Solution

1. Preparation

Gather tools and parts needed for the repair.
Disconnect the battery to ensure safety while working on electrical components.

2. Replace Wiper Fuse

Locate the fuse box, usually found under the dashboard or in the engine compartment.
Identify the wiper fuse using the fuse diagram.
Remove the faulty fuse with a fuse puller or pliers and replace it with a new fuse of the same amperage.

3. Inspect and Replace Wiper Switch

Remove the steering column cover using a screwdriver or socket set.
Disconnect the battery again to prevent electrical shock.
Unplug the wiper switch connector and remove the switch from the steering column.
Install the new wiper switch and reconnect the wiring harness.

4. Test and Replace Wiper Motor (if necessary)

Reconnect the battery.
Use a multimeter to check the voltage at the wiper motor connector while operating the wipers.
If no voltage is present, inspect the wiring and relay. If voltage is present, replace the wiper motor.
To replace the motor:
- Disconnect the wiper arms by removing the retaining nut with a socket set.
- Remove any covers or brackets holding the motor in place.
- Unplug the motor connector and remove the motor.
- Install the new motor, reconnect the wiring, and reassemble the wiper arms.
