Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and turned off.
Disconnect the 12V battery to avoid electrical shock.

2. Inspect and Replace the Wiper Fuse

Locate the fuse panel, typically found in the front trunk or under the dashboard.
Use a fuse puller or pliers to remove the wiper fuse.
Inspect the fuse for continuity; replace it if it is blown (typically a 10A fuse).
Reinsert the new fuse into the correct slot.

3. Check and Repair the Wiper Motor

Remove the plastic cover from the wiper assembly.
Disconnect the wiring harness from the wiper motor.
Using a multimeter, test for power at the motor connector while activating the wipers.
If no power is present, check wiring for damage.
If power is present, replace the wiper motor by unbolting it from its mounting location and installing a new motor.

4. Reassemble and Test

Reattach the wiper arms and plastic cover.
Reconnect the 12V battery.
Test the wiper function by activating them from the control stalk.
