Common Causes Of A Failed Windshield Washer Pump
A windshield washer pump is a vital component of any vehicle’s cleaning system. It delivers washer fluid to the windshield to keep it clean and clear of dirt and debris. However, like any other component, a windshield washer pump can fail, leading to a malfunctioning cleaning system.
Lack Of Fluid In The Reservoir
- The most common cause of a failed windshield washer pump is the lack of fluid in the reservoir. Without enough fluid, the pump will not be able to suck up any liquid, leading to a malfunction.
- It is necessary to always check the fluid level in the reservoir to ensure the system is functioning correctly.
A Clogged Nozzle
- The washer nozzle can get clogged with dirt and debris over time, leading to a malfunction.
- This can prevent washer fluid from being sprayed onto the windshield, causing the washer pump to fail.
- Regular cleaning of the nozzle can prevent this issue.
A Malfunctioning Pump Motor
- If the pump motor is damaged or worn out, the washer pump will not function correctly.
- This can be caused by wear and tear or burn out due to electrical surges.
- Replacing the pump motor is the only solution to this problem.
Damaged Washer Pump Wiring
- Another reason for a failed windshield washer pump is damaged wiring.
- The wiring can get damaged due to exposure to extreme temperatures or due to corrosion.

- Replacing the blown fuse with a new one will restore the pump’s function in this situation.
It is essential to maintain the windshield washer system to keep it functioning correctly. Regularly check the fluid level, clean the nozzle, and inspect the pump’s wiring to avoid common causes of failure. If you notice any issues, such as an unusual noise or a lack of fluid flow, be sure to inspect the pump motor and fuse for potential causes of malfunction.
