Detailed Description

Four Seasons 36495 is an HVAC cut-off switch used in high-pressure A/C systems to monitor refrigerant pressure and interrupt compressor operation when pressure rises beyond the specified threshold. This pressure switch is system mounted and designed for vehicles that require a closed, high cut-out pressure switch with a 12-volt, pin-terminal electrical interface. It is a direct replacement for applications calling for Four Seasons 36495 and is also referenced in Chrysler Daytona, Dodge Daytona, Dodge Shadow, Dodge Spirit, Plymouth Acclaim, and Chrysler LeBaron fitments.

This part cross-references Hayden 5083 for the same application.

What It Helps Address

• A/C compressor cycling caused by high system pressure
• HVAC shutdown triggered by pressure protection logic
• Faulty pressure switch electrical signal at the compressor cut-off circuit
• Loss of A/C protection in high-pressure refrigerant conditions
• Replacement needs for a worn or failed system-mounted pressure switch

Installation Notes and Tips

• Verify the fitting thread size, connector style, and terminal count before installation.
• Confirm the vehicle uses a system-mounted high cut-out pressure switch with closed operation at the specified pressure range.
• Inspect the connector and sealing surfaces for corrosion or damage before connecting the new switch.
• Use the vehicle service information for refrigerant system diagnosis and pressure testing prior to replacement.

Quality Assurance

Four Seasons 36495 is built to meet or exceed OEM requirements for the listed applications. It is part of the Four Seasons Pressure Switch product line and is engineered for direct replacement use in supported Chrysler, Dodge, and Plymouth HVAC systems.
