Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery terminal for safety.

2. Check Fluid Level

Remove the washer fluid reservoir cap.
Verify that the fluid level is at or near the top. If low, refill with appropriate washer fluid.

3. Inspect the Washer Pump

Locate the washer pump at the bottom of the fluid reservoir.
Disconnect the electrical connector from the pump.
Remove the pump from the reservoir by twisting it counterclockwise.
Inspect the pump for cracks or debris, and clean or replace if necessary.

4. Test Electrical Connections

Reconnect the electrical connector to the washer pump.
With the battery reconnected, activate the washer switch while monitoring for voltage at the pump connector using a multimeter.
If there is no voltage, inspect the wiring harness for damage or corrosion.

5. Clear Blockages

If the pump operates but fluid does not reach the windshield, check the hoses for blockages.
Disconnect the hose from the pump and blow air through it to clear any obstructions.
Inspect and clean the nozzles using a fine wire or pin to remove clogs.

6. Reassemble and Test

Reattach the washer pump to the reservoir and secure it by twisting clockwise.
Reconnect the washer fluid hose.
Reconnect the negative battery terminal.
Test the washer system by activating the switch and ensuring fluid sprays onto the windshield.
