Solution

1. Preparation

Gather tools and parts for repair.
Disconnect the battery to prevent electrical shock.

2. Inspect and Replace Fuse

Locate the fuse box, typically located under the dashboard or in the engine compartment.
Use the fuse puller or pliers to remove the wiper fuse.
Check the fuse for continuity. If blown, replace it with a fuse of the same amperage.

3. Test and Replace Wiper Relay

Locate the wiper relay in the fuse box (refer to the owner’s manual for location).
Remove the relay and test it by swapping with a similar relay (if available) to see if the wipers start functioning.
If the wiper relay is faulty, replace it with a new one.

4. Inspect Wiper Motor

Remove the wiper arms by unscrewing the nut at the base of each arm.
Disconnect the wiring harness from the wiper motor.
Apply direct battery power to the wiper motor terminals using jumper wires to see if it operates.
If the motor does not run, replace it with a new wiper motor.

5. Reassemble and Test

Reconnect the wiper motor electrical connector.
Reattach the wiper arms and securely tighten the nuts.
Reconnect the battery.
Test the wipers by activating the control stalk.
