Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle's battery to ensure safety while working on electrical components.

2. Inspect and Replace Wiper Fuse

Locate the fuse box, typically found under the dashboard or in the front trunk.
Remove the cover and locate the windshield wiper fuse (refer to the owner's manual for the exact location).
Use a fuse puller to remove the fuse and inspect it. If the metal strip inside is broken, replace it with a new fuse of the same amperage.
Reinstall the fuse and cover.

3. Test and Replace Wiper Motor (if necessary)

If the fuse is intact, proceed to check the wiper motor.
Disconnect the wiring harness from the wiper motor.
Use a multimeter to check for power at the motor connector when the wiper control is activated.
If no power is present, check the wiring back to the fuse box.
If power is present and the motor does not function, proceed to replace the wiper motor:
- Remove the wiper arms by loosening the retaining nuts and lifting them off the shafts.
- Unbolt the wiper motor from its mounting bracket, usually requiring a socket set.
- Install the new wiper motor by reversing the removal steps and ensure all connections are secure.

4. Reconnect Battery and Test

Reconnect the vehicle's battery.
Test the wipers by activating the control stalk to confirm functionality.
