Warning Signs Your Headlight Washer Pump is Failing:
- Weak or no spray from the headlight washers
- Headlight washers only work intermittently
- Unusual noises (whining, buzzing) coming from the pump area when activated
- Fluid leaking near the headlight washer reservoir or pump
How to Test if This Part is the Problem:
- Check the headlight washer fluid level. Make sure it's full.
- Listen for the pump activating when you try to use the headlight washers. If you hear nothing, the pump may be faulty.
- Check the fuse for the headlight washer system. A blown fuse could prevent the pump from working.
- Use a multimeter to check if the pump is receiving power when the headlight washers are activated. If it's getting power but not working, the pump is likely the issue.
- Disconnect the hose from the pump and try activating the washers. If the pump isn't pushing fluid, it's likely defective.
Common Failure Causes:
- Age and wear: Like any mechanical part, headlight washer pumps wear out over time.
- Clogging: Debris in the washer fluid can clog the pump.
- Freezing: If the washer fluid freezes, it can damage the pump.
- Electrical issues: Corrosion or damage to the wiring can cause the pump to fail.
