Solution

1. Preparation

Gather tools and materials: OBD-II scanner, multimeter, socket set, replacement fuse, and possibly new washer lines or nozzles.
Ensure vehicle is parked on a level surface and engine is turned off.
Disconnect the negative battery terminal to avoid electrical shorts.

2. Check and Replace Fuse

Locate the fuse box, typically found under the dashboard or in the engine compartment.
Remove the cover and identify the washer pump fuse using the diagram.
Inspect the fuse for continuity; replace if blown (typically a 10A fuse).
Reinstall the fuse and cover.

3. Test and Replace Washer Pump

Reconnect the battery terminal.
Locate the washer pump, usually mounted at the bottom of the fluid reservoir.
Use a multimeter to check for power at the pump connector when the washer switch is activated.
If no power is detected, check wiring for damage; repair or replace as needed.
If power is present but the pump does not operate, replace the washer pump:
- Disconnect the electrical connector and fluid lines.
- Remove the pump from the reservoir (may require turning counterclockwise).
- Install the new pump by reversing the removal steps.

4. Clear Blockages

If washer fluid still does not spray, inspect and clear the washer lines:
- Disconnect the lines from the pump and nozzles.
- Use compressed air to blow through the lines and remove any debris.
- Check the nozzles by using a pin to clear any clogs.

5. Reassemble and Test

Reconnect all lines and the pump.
Refill the washer fluid reservoir if necessary.
Test the washer system to ensure proper operation.
