Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and turn off the ignition.
Disconnect the battery negative terminal to ensure safety while working on electrical components.

2. Inspect and Replace the Fuse

Tools Required: Fuse puller or flathead screwdriver
Locate the fuse box (usually under the dashboard or in the engine compartment).
Identify the wiper fuse using the diagram on the fuse box cover.
Remove the fuse using the fuse puller and check if it is blown (the metal strip inside should be intact).
If blown, replace it with a new fuse of the same amperage rating.

3. Test the Wiper Motor

Tools Required: Jumper wires
Locate the wiper motor, usually found at the base of the windshield.
Disconnect the motor's electrical connector.
Using jumper wires, connect the motor directly to the battery (positive to positive, negative to negative).
If the motor operates, it indicates the motor is functional; if not, it may need replacement.

4. Inspect and Repair Mechanical Components

Tools Required: Socket set
Remove the wiper blade arms by loosening the retaining nuts (usually 10mm).
Carefully pull the arms off the splines and set them aside.
Inspect the wiper linkage for any signs of damage or disconnection.
If damaged, replace the wiper linkage assembly as necessary.

5. Reassemble and Test

Reattach the wiper arms to their splines and secure them with the retaining nuts.
Reconnect the battery terminal.
Turn on the ignition and test the wipers for proper function.
