Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a flat surface with the engine off.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Check and Replace Fuse

Tools Required: Fuse puller or needle-nose pliers.
Locate the fuse box and remove the cover.
Identify the windshield wiper fuse using the diagram.
Remove the fuse and check for continuity using a multimeter.
Replace the fuse if it is blown with one of the same amperage.

3. Inspect and Repair Wiper Control Stalk

Tools Required: Screwdriver set (Phillips and flathead).
Remove the steering column cover by unscrewing it.
Disconnect the wiper control stalk connector.
Inspect the stalk for damage; replace if necessary.
Reconnect the stalk and reassemble the steering column cover.

4. Test Wiper Motor

Tools Required: Multimeter, wiring diagram.
Locate the wiper motor (usually beneath the cowl panel).
Disconnect the motor's electrical connector.
Use a multimeter to check for power at the connector when the wiper switch is activated.
If power is present, the motor may need replacement; if not, trace back to the switch.

5. Replace Wiper Motor (if necessary)

Tools Required: Socket set, torque wrench.
