Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle's 12V battery to prevent electrical shock.
Ensure the vehicle is on a flat surface and securely parked.

2. Inspect and Replace the Wiper Fuse

Locate the fuse box, typically under the dashboard or in the trunk.
Identify the wiper fuse using the diagram on the fuse box cover.
Remove the fuse using a fuse puller and inspect for continuity.
If the fuse is blown, replace it with one of the same amperage.

3. Test and Replace the Wiper Motor

Reconnect the battery and turn on the vehicle.
Use a multimeter to check for voltage at the wiper motor connector while activating the wipers.
If there is no voltage, trace the wiring back to the control stalk and fuse box for issues.
If voltage is present but wipers do not move, remove the wiper motor from its mount (typically requires removing bolts).
Install a new wiper motor by reversing the removal process, ensuring correct alignment.

4. Check and Replace the Wiper Control Stalk

If the wiper motor is functional, inspect the control stalk for any damage.
Remove the steering column cover to access the control stalk (may require torx or Phillips screwdriver).
Disconnect the wiring harness from the stalk and replace it with a new one.
Reassemble the steering column cover and test the wipers again.
