Solution

1. Preparation

Gather Tools and Parts: Obtain a multimeter, screwdriver set, and a soft brush for cleaning.
Safety Precautions: Ensure the vehicle is turned off and parked on a level surface.

2. Inspect the Washer Fluid Reservoir

Remove the reservoir cap and check if the fluid is indeed at the correct level.
If the fluid is low, refill with appropriate washer fluid.

3. Test the Washer Pump

Locate the Pump: Find the washer fluid pump, usually located at the bottom of the reservoir.
Check Electrical Connection: Ensure the electrical connector is secured and free of corrosion.
Power Test: Use a multimeter to check for voltage at the pump connector when the washer switch is activated. Voltage should be present; if not, investigate the switch or wiring.

4. Check for Blockages

Disconnect the fluid lines from the pump and spray nozzles.
Use compressed air to blow through the lines to clear any blockages.
Clean the nozzles with a soft brush or needle if debris is present.

5. Reassemble and Test

Reconnect the fluid lines and pump.
Fill the reservoir if necessary.
Activate the washer system to check for fluid spray operation.
