Solution

1. Preparation

Gather tools: socket set, multimeter, OBD-II scanner, and safety gloves.
Disconnect the vehicle's battery to prevent electrical shorts.
Ensure the vehicle is parked on a level surface with the wipers in the "off" position.

2. Check and Replace Fuses

Locate the fuse box (usually under the dashboard or in the trunk).
Refer to the owner's manual for the specific fuse related to the windshield wipers.
Remove the fuse and inspect it for continuity. If blown, replace it with a fuse of the same amperage.

3. Inspect and Repair Wiper Motor

Locate the wiper motor, usually found beneath the cowl panel at the base of the windshield.
Disconnect the electrical connector from the wiper motor.
Using a multimeter, test the motor for continuity. If there is no continuity, the motor needs to be replaced.
If continuity is present, reconnect the motor and test its operation by applying direct power to the motor terminals.

4. Replace the Wiper Control Stalk (if necessary)

Remove the steering column cover using a socket set.
Disconnect the control stalk connector.
Replace the control stalk with a new part and reconnect it.
Reassemble the steering column cover.

5. Reassemble and Test

Reconnect the vehicle's battery.
Test the wiper system by activating it from the control stalk.
Ensure the wipers operate smoothly and the wiper fluid sprays if applicable.
