Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and turn off the ignition.
Disconnect the battery to ensure safety during repairs.

2. Check and Replace Wiper Fuse

Locate the fuse box (usually under the dashboard or in the engine compartment).
Remove the cover and identify the wiper fuse using the diagram.
Inspect the fuse; if blown, replace it with one of the same amperage (typically 20A).

3. Test and Replace Wiper Motor

Reconnect the battery and activate the wipers while measuring voltage at the motor connector.
If no voltage is present, the motor may need to be replaced.
If voltage is present but the motor does not operate, remove the motor:
- Disconnect the wiring harness.
- Unbolt the motor from its mounting.
- Install a new motor in reverse order and reconnect the wiring.

4. Inspect and Repair Wiper Linkage

If the wipers are stuck, remove the wiper arms using a puller if necessary.
Inspect the linkage for wear or damage.
Lubricate the linkage if it appears to be stiff.
Replace any damaged components and reassemble the wiper arms.

5. Replace Wiper Switch (if necessary)

Remove the steering column cover to access the wiper switch assembly.
Disconnect the wiring harness and unbolt the switch.
Install the new switch, reconnect the wiring, and reassemble the column cover.
