Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and turn off the ignition.
Disconnect the 12V battery to prevent any electrical shock.

2. Fuse Inspection and Replacement

Locate the fuse box as described in the owner's manual.
Identify the wiper fuse using the fuse diagram on the cover.
Remove the fuse using a fuse puller or pliers.
Inspect the fuse for any signs of damage (broken filament).
If damaged, replace it with a new fuse of the same amperage rating.

3. Wiper Control Stalk Inspection

Remove the steering column cover by unscrewing the screws securing it.
Gently pull apart the column cover to expose the wiring harness connected to the wiper control stalk.
Check for any visible damage or disconnections in the wiring.
If necessary, replace the control stalk with a new unit.

4. Wiper Motor Access and Testing

Remove the wiper arms by loosening the nuts securing them to the motor shafts.
Lift the arms off and set them aside.
Access the wiper motor by removing any necessary panels or covers in the engine compartment.
Disconnect the wiper motor connector and inspect the wiring for damage.
Apply power directly to the motor terminals using jumper wires to test functionality.
If the motor does not operate, replace it with a new wiper motor.

5. Reassembly

Reattach the wiper motor and reconnect any wiring.
Replace the wiper arms and secure them with the nuts.
Reattach the steering column cover and secure it with screws.
Reconnect the 12V battery.
