Mercedes Windshield Washer Pump - Genuine Mercedes 0998660100

Product Information

A windshield washer pump is a small electric pump in a vehicle’s windshield washer system. Its function is to draw windshield washer fluid from the reservoir and spray it through the nozzles onto the windshield. This helps clean the windshield of dirt, bugs, and debris, improving visibility for safe driving.

• Washer Fluid Not Spraying: The most common sign of a failing pump is that no washer fluid sprays onto the windshield when the system is activated, even if the reservoir is full
• Washer Fluid Leaks: If the pump housing or connections are damaged, it may cause washer fluid to leak under the vehicle, especially near the front or rear
• Low or Inconsistent Spray Pressure: A partially failing pump may produce weak or inconsistent fluid flow, resulting in only a small amount of fluid reaching the windshield

You may not realize this, but the parts that make up your Mercedes-Benz are not necessarily manufactured by Mercedes-Benz.

In fact, many of these manufacturers have been making parts for Mercedes-Benz for decades. In our industry these manufacturers are called OEM (Original Equipment Manufacturers), and these are often brands you recognize, including Lemforder, ZF, Sachs, Bosch, Valeo, Zimmermann, Siemens VDO, Corteco, and more. Don’t be surprised to open that Genuine Mercedes-Benz parts box and find an OEM branded part inside, simply with the addition of a Mercedes-Benz logo.
