Detailed Product Description

Four Seasons 20951 is used in HVAC systems where accurate refrigerant pressure feedback is required for compressor and climate-control operation. This pressure switch transducer is engineered for direct replacement service on a wide range of vehicles, including 2005-2012 Chrysler 300, 2006-2011 Dodge Charger, and 2007-2011 Jeep Wrangler applications. It also cross-references UAC SW10080C for the same application.

As an OE-style HVAC pressure transducer, part number 20951 is built for system-mounted use and features the connector and thread configuration commonly found on Chrysler-family platforms. The variable output design supports pressure-based control logic used by the vehicle HVAC system.

What It Helps Address

• HVAC compressor cycling caused by a faulty pressure signal
• Air conditioning shutdown related to incorrect refrigerant pressure readings
• Intermittent A/C operation from worn electrical contacts or connector issues
• Pressure switch replacement needs on Chrysler, Dodge, Jeep, Ram, and Plymouth models
• System-mounted transducer failures in climate-control circuits

Installation Notes and Tips

Verify connector shape, terminal count, and M10 x 1.25 thread size before installation. This part is system mounted and uses a weather-pack connection. Some applications may require use of switch harness 20954. Confirm vehicle-specific fitment for models such as Chrysler 300, Dodge Ram 1500, and Jeep Grand Cherokee before ordering.

Quality Assurance

Four Seasons 20951 meets or exceeds OEM specifications for the listed applications. The pressure switch is built with plastic and metal materials and is designed to match the electrical and mounting requirements used across the supported vehicle range.
