Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative battery terminal to prevent electrical shorts.
Ensure the vehicle is parked on a level surface.

2. Inspect and Replace the Washer Pump

Tools Required: Socket set, screwdriver set, multimeter.
Locate the windshield washer pump, typically found at the bottom of the washer fluid reservoir.
Disconnect the electrical connector from the pump.
Remove the pump by unscrewing or unclipping it from the reservoir.
Sub-Step: Use a multimeter to check the pump's resistance; if it reads infinite resistance, replace the pump.
Install the new pump by reversing the removal steps and reconnecting the electrical connector.

3. Check and Clear Hoses

Inspect the washer fluid hoses from the pump to the spray nozzles.
Disconnect the hoses and check for blockages; clear any clogs with compressed air if necessary.
Replace any damaged or cracked hoses with new ones.

4. Replace the Washer Fluid Switch (if necessary)

If the washer switch was found to be faulty during testing, remove the steering column covers.
Disconnect the wiring harness from the switch.
Remove the switch and replace it with a new one.
Reassemble the steering column covers.

5. Refilling and Testing

Refill the washer fluid reservoir with appropriate washer fluid.
Reconnect the negative battery terminal.
Activate the washer system to check for proper operation.
