Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative terminal of the battery for safety.

Tools Required:

Screwdriver set
Multimeter
Socket set
Pliers

2. Check and Replace Fuse

Locate the fuse box (usually found in the glove compartment or under the dashboard).
Remove the fuse in question (refer to the owner's manual for the specific fuse location).
Inspect the fuse; if blown, replace it with a fuse of the same amperage.

3. Inspect the Wiper Motor

Remove the wiper arms by loosening the retaining nuts with a socket set.
Pull the wiper arms off the splines gently.
Disconnect the wiper motor connector and use a multimeter to check for voltage when the wiper switch is engaged.
If there's no voltage, trace the wires back to the switch to find any breaks or shorts.

4. Test the Wiper Motor

Connect the wiper motor directly to a power source (use a 12V battery).
If the motor runs, it is functional; if not, replace the wiper motor.

5. Inspect and Repair Wiper Linkage

Check the wiper linkage for any loose or broken components.
Tighten any loose bolts or replace damaged parts as necessary.
