Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the vehicle battery to prevent electrical short circuits.

2. Check Washer Fluid Level

Open the hood and locate the washer fluid reservoir.

Tools Required: Multimeter, socket set
Locate the washer pump at the bottom of the washer fluid reservoir.
Disconnect the wiring harness from the pump.
Use a multimeter to check for voltage at the connector while activating the washer switch. If voltage is present, the pump may be faulty.
If no voltage, trace back to the switch or fuse.

Look for any cracks, leaks, or blockages.
Remove any clogs found using compressed air or by replacing the affected hose sections.
