Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the 12V battery to prevent any electrical shorts while working with the wiper system.
Gather necessary tools and parts.

2. Inspect and Replace Fuse

Locate the fuse box under the dashboard on the driver’s side.
Identify the wiper fuse using the fuse diagram.
Remove the fuse using a fuse puller or needle-nose pliers.
Inspect the fuse for continuity; if blown, replace it with a new fuse of the same amperage.

3. Check Wiper Motor Connection

Remove the covers and any trim necessary to access the wiper motor.
Disconnect the wiring harness from the wiper motor.
Inspect the terminals for corrosion or damage.
Reconnect the wiring harness securely.

4. Test Wiper Motor

Reconnect the battery.
Use a multimeter to check for voltage at the wiper motor connector while activating the wiper switch.
If voltage is present, the issue may lie within the wiper motor itself. If no voltage is present, the problem may be upstream (e.g., switch or wiring).

5. Replace Wiper Motor (if needed)

If the motor is defective, remove it by unscrewing the mounting bolts.
Disconnect the motor from the linkage.
Install the new wiper motor by reversing the removal steps, ensuring all connections are secure.
