- Loose or damaged hose connections: Check the hoses connecting the windshield wiper fluid reservoir to the nozzles to ensure they are properly attached and free of leaks.
- Faulty check valve: The check valve is a small device that prevents the wiper fluid from flowing back into the reservoir. If the check valve is damaged or not functioning correctly, it can cause the fluid to leak out when the stick is pressed.
- Leaking pump: The pump that draws wiper fluid from the reservoir and sprays it onto the windshield can develop leaks. This can be due to wear and tear, or damage to the pump seal.
- Clogged or blocked nozzles: If the nozzles that spray the wiper fluid onto the windshield are clogged or blocked, it can prevent the fluid from being dispersed properly, causing it to leak out instead.
- Overflowing reservoir: If the windshield wiper fluid reservoir is filled too high, it can cause the fluid to overflow and leak out when the stick is pressed.
To resolve the issue, you can inspect and tighten any loose hose connections, replace the check valve if necessary, check and replace the pump if it is leaking, clean or unclog the nozzles, and maintain the proper fluid level in the reservoir.
