Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical components.

2. Inspect and Replace the Fuse

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 a fuse puller or pliers.
Test the fuse with a multimeter; if blown, replace with a new fuse of the same amperage (often 10-20A).

3. Check and Replace the Wiper Motor

Remove the wiper arms by loosening the retaining nuts with a socket set.
Carefully pull the wiper arms off the motor shafts.
Unplug the wiper motor connector from the wiring harness.
Using a multimeter, test the motor for proper voltage when the wiper switch is activated.
If the motor is faulty, replace it with a new one. Install in reverse order:
- Plug in the new motor connector.
- Reattach the wiper arms and tighten the retaining nuts to the manufacturer’s torque specifications (usually around 10-15 Nm).

4. Inspect and Repair Wiper Linkage

If the motor is functional, inspect the wiper linkage for wear or disconnection.
Remove any covers to access the linkage assembly.
If any linkage components are damaged or disconnected, replace them and ensure all connections are tight.

5. Washer Fluid System Check

Remove the washer fluid reservoir cap and check the fluid level.
If low, fill with the appropriate washer fluid.
Test the washer pump by activating the wiper switch to spray. If no fluid sprays, check the pump by removing and testing it for functionality. Replace if defective.
