Solution

1. Preparation

Gather necessary tools and safety equipment.
Disconnect the vehicle battery to ensure safety during repairs.

2. Inspect the Wiper Fuse

Locate the fuse box: Open the driver’s side door and find the fuse panel near the dashboard or under the hood.
Remove the wiper fuse using a fuse puller or pliers.
Inspect the fuse for any signs of damage or a blown filament.
If blown, replace it with a fuse of the same amperage (usually specified in the owner’s manual).

3. Check the Wiper Motor Connection

Remove any covers or panels obstructing access to the wiper motor.
Visually inspect the wiring harness and connectors for corrosion or damage.
Secure any loose connections and clean corroded terminals using electrical contact cleaner.

4. Test the Wiper Switch

Locate the wiper switch on the steering column.
Using a multimeter, check for continuity while operating the switch.
If the switch is faulty, replace it with a new unit.

5. Verify the Wiper Relay

Locate the wiper relay within the fuse box.
Remove the relay and test it by swapping it with a relay of the same type.
If the wipers operate with the swapped relay, replace the faulty relay.

6. Inspect Wiper Linkage and Motor Assembly

If the motor is operational, check the wiper linkage for any disconnections or damage.
Ensure that the motor shaft is securely connected to the linkage.
Replace any broken or worn components as necessary.
