Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the engine off.
Disconnect the negative terminal of the battery to prevent electrical shock.

2. Inspect and Replace the Fuse

Locate the fuse box, typically under the dashboard or in the engine compartment.
Remove the cover and identify the wiper fuse using the diagram on the cover.
Pull the fuse out using fuse pullers and inspect for continuity; replace if blown.
Reinstall the fuse and cover.

3. Test the Wiper Motor

Reconnect the battery terminal.
Disconnect the wiper motor's electrical connector.
Use a multimeter to check for continuity at the motor terminals.
If no continuity is detected, connect a jumper wire directly to the battery to test the motor’s operation.
If the motor runs, the issue is likely with the wiring or switch.

4. Check and Replace the Wiper Control Switch

Remove the steering column cover by unscrewing the screws securing it.
Disconnect the electrical connector from the switch.
Remove the switch from the steering column.
Replace it with a new switch if faults are found.

5. Inspect and Repair the Wiring

Trace the wiring harness from the wiper motor to the switch.
Check for damaged insulation, corrosion, or breaks in the wiring.
Repair any damaged wires with electrical tape or replace sections as necessary.
