Steps

Goal: Confirm the symptom, rule out fluid level and nozzles, then isolate the pump or fuse fault.

  • Turn the ignition to accessory or run. Activate the washer.
  • Good: No spray from the nozzles—washer fault. Proceed to Check fluid and nozzles.
  • Bad: Washer sprays—no problem.

Check fluid and nozzles

Goal: Rule out empty reservoir and clogged nozzles.

  • Open the hood. Check the washer fluid reservoir. Add fluid if empty or low.
  • Use a pin to clear debris from each nozzle hole. Do not use a large object.
  • Good: Reservoir is full and nozzles are clear. Proceed to Pump and fuse.
  • Bad: Was empty or clogged—add fluid or clear nozzles and test.

Pump and fuse

Goal: Check the washer fuse, hoses, and pump.

  • Activate the washer. Listen for the washer pump. If you hear it but no spray, check the hoses for disconnection or kinks.
  • Check the washer fuse. Replace if blown with the same amperage. If it blows again, call a mechanic.
  • If the pump does not run and the fuse is good, the pump may have failed—replace it or call a mechanic.
  • Good: You found and fixed the fault—replaced fuse, reconnected hose, or replaced pump.
  • Bad: Pump has failed—replace it or call a mechanic.
