Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the ignition is off.
Disconnect the negative battery terminal to prevent any electrical shorts.

2. Check and Replace the Fuse

Locate the fuse box, which is usually under the dashboard or in the trunk.
Refer to the vehicle’s manual to identify the correct fuse for the windshield wipers.
Remove the fuse using a fuse puller or pliers.
Inspect the fuse for continuity; replace it if it is blown with a fuse of the same amperage.

3. Inspect and Replace the Wiper Motor

Remove the windshield wiper arms by loosening the retaining nuts with a socket wrench.
Carefully lift the arms off the splines and set them aside.
Disconnect the electrical connector from the wiper motor.
Remove the mounting bolts securing the wiper motor to the vehicle.
Install the new wiper motor in the reverse order, making sure it is securely mounted and connected.

4. Reassemble and Test

Reattach the windshield wiper arms to the motor splines, ensuring they are positioned correctly.
Tighten the retaining nuts securely to the manufacturer's specifications.
Reconnect the negative battery terminal.
Turn on the vehicle and test the wipers for proper operation across all settings.
