Four Seasons 37361 HVAC Pressure Transducer

HVAC Pressure Transducer for Mercedes-Benz

Four Seasons 37361 is a system-mounted HVAC pressure transducer built for Mercedes-Benz and Sprinter applications that use a 3-pin, rectangular male connector and a 3/8 in. x 24 male fitting. It meets or exceeds OEM requirements and uses a Weather Pack-style connection for dependable signal transfer in the air conditioning system.

Use this Four Seasons Pressure Switch line component when servicing Mercedes-Benz C300, E350, GLC300, GLE350, Sprinter, and other listed models that require accurate refrigerant pressure monitoring. Part number 37361 is a direct-fit replacement for many late-model and earlier Mercedes-Benz HVAC systems.

Key Features

• HVAC pressure transducer for system-mounted applications
• 3-pin rectangular male connector with pin terminals
• Male fitting with 3/8 in. x 24 thread size
• Variable open/closed operation for pressure-based signal control
• Weather Pack connection for improved sealing at the connector
• Meets or exceeds OEM specifications

Product Details

The Four Seasons Pressure Switch line focuses on HVAC control components that monitor refrigerant pressure and relay that information to the vehicle’s climate control system. This transducer is used in Mercedes-Benz HVAC systems where stable pressure feedback is needed for compressor operation and system protection. Part number 37361 cross-references UAC SW11178C for the same application.

Compatible vehicle coverage includes many Mercedes-Benz models such as C300, CLA250, E350, GLC300, GLE350, GLS450, S500, and Sprinter, along with select Dodge Sprinter applications. The broad fitment makes this a practical replacement for diagnosing pressure-related HVAC faults across multiple chassis and model years.

Common Issues This Part Can Address

• HVAC compressor cycling too frequently
• A/C system not engaging due to incorrect pressure signal
• Fault codes related to refrigerant pressure monitoring
• Intermittent cooling performance caused by a failing transducer
• Climate control shutdown from inaccurate system pressure input

Installation Notes and Tips

• Confirm the connector style, terminal count, and 3/8 in. x 24 fitting before installation.
• Inspect the refrigerant circuit for leaks or contamination before replacing the sensor.
• Recover refrigerant and follow proper HVAC service procedures before removal.
• Clear stored HVAC or engine fault codes after installation and verify system operation.
• Use the vehicle’s exact year, make, and model to confirm application match for Mercedes-Benz C300, E350, GLC300, GLE350, and Sprinter platforms.

Quality Assurance

Four Seasons 37361 is built to meet or exceed OEM specifications for fit and function. The Four Seasons Pressure Switch line is engineered for direct replacement use in factory-style HVAC systems, supporting consistent pressure signal performance across the listed Mercedes-Benz applications.
