Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the negative terminal of the battery to ensure safety.
Clear the work area around the wiper motor and linkage.

2. Replace the Wiper Fuse

Locate the fuse box under the dashboard or hood as per the owner's manual.
Remove the wiper fuse using a fuse puller or pliers.
Inspect the fuse; if blown, replace it with a new fuse of the same amperage (typically 20A).
Reinstall the fuse and reconnect the battery.

3. Replace the Wiper Motor (if necessary)

Remove the wiper arm nuts using a socket set and lift off the wiper arms.
Disconnect the wiper motor wiring harness.
Remove the mounting bolts securing the wiper motor to the vehicle.
Install the new wiper motor in reverse order.
- Torque the mounting bolts to the manufacturer's specifications (typically 10-15 ft-lbs).
Reconnect the wiper motor wiring harness and reattach the wiper arms.

4. Test the Wiper System

Reconnect the negative terminal of the battery.
Turn on the ignition and test the wipers in all modes to ensure proper operation.
