Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, socket set, flathead screwdriver, and cleaning supplies.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Check Washer Fluid Level

Open the hood and locate the windshield washer fluid reservoir.
Remove the cap and visually inspect the fluid level; add fluid if necessary.

3. Inspect and Test the Washer Pump

Locate the washer pump, usually found at the bottom of the washer fluid reservoir.
Disconnect the electrical connector from the washer pump.
Use a multimeter to check for power at the connector while activating the washer switch (should read approximately 12V).
If no power is detected, trace the wiring back to the switch for any faults.

4. Clean or Replace the Washer Nozzles

Use a flathead screwdriver to carefully remove any debris around the washer nozzles.
Use a pin or needle to clear any clogs in the nozzles.
If the nozzles remain clogged after cleaning, consider replacing them.

5. Test the Washer Fluid Lines

Inspect the fluid lines for any visible cracks or leaks.
If leaks are found, replace the damaged sections of the line.
If the lines appear intact, reconnect them and secure all fittings.

6. Reassemble and Test

Reconnect the washer pump and test the system by activating the washer switch.
Monitor for proper fluid spray pattern and coverage.
