NISSAN 28920-1E400 Windshield Washer Motor

The genuine NISSAN 28920-1E400 windshield washer motor (washer pump) is a premium-quality OEM part responsible for the reliable operation of the windshield cleaning system. This electric pump ensures the delivery of washer fluid under proper pressure from the reservoir to the spray nozzles, guaranteeing rapid and effective windshield cleaning in all weather conditions.

Technical Features and Specifications:

• Rated Voltage: 12V direct current (DC)
• Connector Type: 2-pin precision electrical connector for stable contact
• Operating Principle: Electric motor-driven centrifugal pump
• Mounting Location: Mounts directly onto the washer fluid reservoir (secured with a rubber sealing grommet)
• Material Quality: Weather- and chemical-resistant plastic housing that withstands winter antifreeze fluids and engine compartment temperature fluctuations

Role and Importance of the Washer Motor:

The windshield washer motor is a critical safety component. Rapid removal of dust, mud, insect residue, and winter road salt spray from the windshield is vital for maintaining clear visibility. The genuine Nissan component guarantees exact fitment, factory-specified pressure levels, and long service life compared to lower-quality aftermarket alternatives.

Typical Signs of Failure:

• Silent Operation: The characteristic humming sound of the motor is absent when activating the washer switch (electrical issue or burned-out motor).
• Low Pressure: The motor operates, but fluid only trickles weakly from the nozzles (internal wear or impeller damage).
• Leakage: Fluid leaks around the pump housing or reservoir connection, which can cause damage to electrical terminals.
• Intermittent Operation: The pump functions only sporadically due to poor internal electrical contact or corrosion.
