Four Seasons 36485 A/C Clutch Cycle Switch

Four Seasons 36485 A/C Clutch Cycle Switch

The Four Seasons Pressure Switch 36485 is a system-mounted A/C clutch cycle switch built for 12-volt HVAC systems. It uses a female M12 x 1.50 thread, a 2-pin male terminal connection, and a weather-pack design for secure electrical routing in demanding underhood conditions.

For Ford, Lincoln, Mazda, Mercury, and Nissan applications, this pressure switch helps regulate compressor cycling by responding to system pressure changes. Four Seasons 36485 meets or exceeds OEM requirements and is a direct-fit style replacement for many vehicles, including Ford E-350 Super Duty, Ford F-150, and Ford Explorer applications.

Detailed Description

Four Seasons 36485 is a cycling pressure switch used in automotive HVAC systems to monitor refrigerant pressure and control A/C compressor clutch operation. The switch is designed for system mount installation and is commonly used on Ford truck, van, and SUV platforms, along with select Lincoln, Mazda, Mercury, and Nissan models. If you are servicing an A/C system on a Ford Ranger, Ford Mustang, or Lincoln Town Car, this part number is a relevant OE-style replacement to verify against your original switch.

This part cross-references UAC SW9701C for the same application.

What It Helps Address

• A/C compressor cycling that is inconsistent or not responding to pressure changes
• Loss of compressor engagement caused by a faulty pressure switch
• HVAC pressure signal issues in system-mounted switch locations
• Electrical connection problems at the A/C pressure switch terminal interface
• Replacement needs on Ford E-150, Ford F-250 Super Duty, and Ford Explorer HVAC systems

Installation Notes and Tips

Confirm the original connector style, thread size, and pressure-switch location before installation. Verify the vehicle’s refrigerant system specification and compare the existing switch to Four Seasons 36485 to ensure the correct pressure range and terminal configuration. Because fitment varies by year and model, check the application details for your Ford, Lincoln, Mazda, Mercury, or Nissan vehicle before purchase.
