Solution

1. Preparation

Gather tools: screwdriver set, multimeter, OBD-II scanner, and replacement fuse if necessary.
Ensure the vehicle is turned off and parked on a flat surface.

2. Inspect and Replace Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Identify the fuse for the windshield wipers using the fuse diagram (usually on the cover).
Remove the fuse with a fuse puller or pliers.
Inspect the fuse for any signs of damage or breakage.
If the fuse is blown, replace it with a new one of the same amperage rating.

3. Test and Replace Wiper Control Stalk

Remove the steering column cover using a screwdriver.
Disconnect the electrical connector from the wiper control stalk.
Test the stalk using a multimeter to ensure it is functioning correctly (check continuity).
If defective, replace the wiper control stalk by installing a new one and reconnecting the electrical connector.

4. Inspect and Replace Wiper Motor

Disconnect the battery to ensure safety.
Locate the wiper motor, typically under the hood near the base of the windshield.
Remove any covers or brackets securing the motor.
Disconnect the motor's electrical connector and remove the mounting bolts.
Remove the old wiper motor and install the new one by reversing the steps.
Reconnect the battery.
