Solution

1. Preparation

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

2. Inspect and Test Wiper Control Stalk

Remove the steering column cover using a socket set.
Disconnect the electrical connector from the wiper control stalk.
Use a multimeter to test for continuity in the stalk when operated in different positions (specifically 'off' and 'on').
Replace the control stalk if it shows no continuity in the 'off' position.

3. Check and Replace Wiper Relay

Locate the wiper relay in the fuse box (refer to the owner's manual for exact location).
Remove the relay and visually inspect it for damage.
Test the relay using a multimeter or swap it with a similar relay.
Replace the relay if it fails the test, ensuring it's seated properly.

4. Inspect Wiper Motor

Locate the wiper motor, usually found under the hood at the base of the windshield.
Disconnect the motor's electrical connector and inspect for corrosion or damage.
Test the motor by connecting it directly to the battery (ensure the polarity is correct).
Replace the motor if it does not operate when connected directly.

5. Reassemble and Connect Battery

Reattach any components removed during the inspection.
Reconnect the negative battery terminal securely.
Ensure all tools are removed from the engine bay.
