Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical shock.

2. Check and Replace Fuse

Locate the fuse box under the dashboard or hood.
Remove the wiper fuse using a fuse puller.
Inspect the fuse for continuity; replace with the same amperage if blown.

3. Test and Replace Wiper Motor (if necessary)

Reconnect the battery temporarily.
Use a multimeter to check for voltage at the motor connector while activating the wiper switch.
If no voltage is present, troubleshoot wiring; if voltage is present, proceed to replace the motor.
Disconnect the battery again before replacing the motor.
Remove any components obstructing access to the wiper motor (e.g., cowl cover).
Disconnect the wiper motor connector and remove the mounting bolts.
Install the new wiper motor in reverse order, ensuring proper alignment.
Reconnect the battery and test the wipers.

4. Inspect and Repair Wiper Linkage (if necessary)

If the wiper motor operates but wipers do not move, remove the wiper arms from the splines.
Remove the cowl cover to access the linkage.
Inspect the linkage for any wear or disconnection; lubricate moving parts if necessary.
Replace any damaged components and reassemble.
