Guide to the 2009-2020 Mercedes-Benz Sprinter Windshield Washer Pump
Don't let a faulty washer pump compromise your visibility; understand your replacement options.
- A silent pump often points to an electrical failure, while a humming pump with no spray suggests a clog or empty reservoir.
- Replacing the pump is a DIY-friendly job, typically requiring access through the passenger-side wheel well.
- Always replace the small rubber grommet with the pump to prevent future leaks.
- Verify if your Sprinter has headlight or rear washers before ordering, as this can affect which pump you need.
Is Your Sprinter's Washer Pump Failing?
A non-functional windshield washer system is more than an inconvenience—it's a safety hazard. If you activate the washers and nothing happens, or the spray is weak, it's time to diagnose the problem. For Sprinter owners, the issue often points to a few common culprits, with the washer pump being a primary suspect.
Symptoms of a Bad Windshield Washer Pump
Look out for these clear signs of failure:
- Silence is Not Golden: When you press the washer button, you should hear a distinct humming sound from the pump. If it's silent, the pump may not be receiving power or its internal motor has failed.
- Pump Runs, But No Fluid Sprays: If you can hear the pump working but no fluid comes out, the system could have a blockage, a disconnected hose, or the pump itself isn't generating enough pressure. Sometimes, the filter screen at the pump's intake gets clogged with debris.
- Weak or Inconsistent Spray: A dying pump may lose its ability to create strong, consistent pressure, resulting in a weak spray that barely reaches the windshield.
- Leaks: Puddles of blue washer fluid under the front of your van can indicate a cracked reservoir or a bad seal where the pump pushes into the tank. The rubber grommet that seals the pump is a common failure point.
Choosing the Right Aftermarket Pump
When replacing the washer pump on your Sprinter, you have a choice between OEM (Original Equipment Manufacturer) and aftermarket parts. While an OEM part from Mercedes-Benz guarantees a perfect fit, a quality aftermarket part can offer significant savings without sacrificing reliability.
Aftermarket brands like Trico offer direct-fit replacement pumps designed for easy installation. These parts are engineered to meet or exceed the performance of the original pump and are a cost-effective solution for a DIY repair. Other brands like VDO, Febi, and Contitech are also commonly available for the Sprinter. VDO is often the original equipment supplier, meaning their aftermarket part can be identical to the dealer part, just in a different box.
Pro Tip: Check the Grommet!
The small rubber grommet that seals the pump into the reservoir is a frequent source of leaks. It's highly recommended to replace this grommet whenever you replace the pump. It's an inexpensive part that ensures a leak-free repair.
Replacing the Sprinter Washer Pump
This is a job most DIY-inclined owners can handle. The washer fluid reservoir and pump are typically located in the engine bay, often behind a headlight or accessible by removing the front passenger-side wheel and wheel well liner. The pump itself is simply press-fit into the reservoir. After disconnecting the electrical connector and hoses, you can pull the old pump out, push the new one in, and reconnect everything.

Some Sprinter models have options for headlight washers or a rear window washer, which may use a different or additional pump. Always verify the part number and check if your van has these features before ordering to ensure you get the correct pump for the windshield.
Frequently Asked Questions
Is it difficult to replace a Sprinter washer pump?
No, it is generally considered an easy repair. It requires basic hand tools and can typically be completed in under an hour. Accessing the pump is the main challenge, usually involving the removal of the wheel well liner.
My wipers work, but the washer doesn't. Could it be a fuse?
It's possible, but on many Sprinters, the washer pump and wiper motor share a fuse. If your wipers are working, the fuse is likely okay. The problem is more likely the pump itself, the switch, or the wiring between them.
Why did my washer pump stop working in the winter?
Washer fluid can freeze in cold temperatures if it doesn't have a high enough concentration of antifreeze. This can block the lines and nozzles and even damage the pump if it runs while the fluid is frozen. Always use a winter-grade washer fluid rated for the temperatures in your area.
I hear the pump, but no water comes out. What should I check first?
First, make sure the washer fluid reservoir is full. If it is, check for clogged nozzles by clearing them with a small pin. 🎬 Watch this quick fix for Sprinter windscreen washer issues. Next, check for disconnected or cracked hoses. If those are fine, the filter at the base of the pump is likely clogged with slime or debris from old fluid.
