* Clogged nozzles: The most common issue. Try using a thin needle or straightened paperclip to carefully clear any debris blocking the spray holes.
* Low washer fluid: Make sure you have enough washer fluid in the reservoir.
* Frozen fluid: In cold weather, the fluid may be frozen. Use de-icer fluid appropriate for the temperature.
* Pump failure: The washer pump might be malfunctioning. You'll likely hear a whirring sound if it's trying to work but failing. This usually requires replacement.
* Hose blockage: A hose leading to the nozzles could be clogged or kinked. This requires more investigation to locate.
* Faulty switch: The switch in the vehicle's interior that activates the washers may be broken.
If cleaning the nozzles doesn't solve the problem, you'll need to investigate further, possibly taking it to a mechanic.
