* Low Washer Fluid: The most obvious reason! Check the washer fluid reservoir (usually a transparent container under the hood) to see if it needs refilling.
* Clogged Nozzles: The tiny nozzles that spray the fluid can become clogged with debris. Try gently probing them with a thin needle or paperclip. Sometimes a strong blast of compressed air can clear them.
* Frozen Fluid: In cold weather, the washer fluid can freeze, preventing it from flowing. Use winter-grade washer fluid designed to withstand freezing temperatures.
* Pump Failure: The electric pump that pushes the fluid through the system can fail. This requires replacement. You might hear a whirring sound if the pump is trying to work but is failing.
* Fuse Blown: The washer pump is controlled by a fuse. Check your owner's manual to locate the fuse for the windshield washers and see if it's blown.
* Wiring Issues: A break or short in the wiring to the pump could prevent it from working. This often requires professional diagnosis.
* Switch Malfunction: The switch on your dashboard that activates the washers might be faulty.
Troubleshooting Steps:
1. Check the fluid level.
2. Inspect the nozzles for clogs.
3. Listen for the pump motor when you activate the switch. (If you hear nothing, it might be the pump, fuse, or wiring.)
4. Check the fuse.
5. If all else fails, consult a mechanic or an auto parts store for further diagnosis.
Without more information about what's happening (e.g., is there no sound at all? Are the nozzles clogged? Is the fluid frozen?), it's impossible to give a more specific answer.
