Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and turned off.
Disconnect the 12V battery to prevent electrical shorts.

2. Check and Replace Fuses

Locate the fuse box: typically under the dashboard on the driver's side.
Identify the wiper fuse using the fuse diagram.
Remove the fuse with a fuse puller and inspect for continuity.
- If blown, replace it with a new fuse of the same amperage (usually 15A).

3. Inspect and Test Wiper Motor

Reconnect the 12V battery.
Access the wiper motor (may require removing the cowl panel).
Disconnect the motor connector and test for voltage at the connector while activating the wipers.
- If voltage is present but the motor does not operate, replace the wiper motor.
- If no voltage is present, continue to the next step.

4. Replace Wiper Control Stalk (if necessary)

Remove the steering column cover.
Disconnect the wiring harness from the wiper control stalk.
Replace with a new stalk and reconnect the wiring.
Reassemble the steering column cover.

5. Final Assembly

Reinstall the cowl panel and ensure all clips are secured.
Reconnect the battery and check for any warning lights on the dashboard.
