Universal Air SW3004C A/C Thermostat

Thermostatic A/C Control for Ford and Mercury HVAC Systems

Universal Air SW3004C is a thermostatic switch for A/C clutch and compressor control in select Ford and Mercury applications. It is used in HVAC systems that require a system-mounted thermostatic switch to regulate evaporator temperature and compressor cycling.

Key Features

• Thermostatic switch for A/C thermostat service
• Fits select Ford Taurus, Ranger, Thunderbird, F-Series, and Econoline applications
• Also used on select Mercury Cougar, Grand Marquis, Marquis, and Sable models
• Application-specific fitment for vehicles with system mount configurations where noted
• Part number SW3004C for catalog and service matching

Detailed Description

Universal Air SW3004C is an A/C thermostat used in HVAC systems that control compressor operation based on evaporator temperature. This thermostatic switch supports proper cycling in older Ford and Mercury platforms, including Ford Taurus, Ford Ranger, Ford Thunderbird, Ford F-150, Ford F-250, Ford F-350, and Econoline vans, as well as Mercury Cougar, Grand Marquis, Marquis, and Sable applications. Use SW3004C when servicing a system that calls for this specific thermostatic switch configuration.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Compressor short cycling caused by a faulty thermostat switch
• A/C compressor staying engaged longer than specified
• Inconsistent evaporator temperature control
• Poor cabin cooling performance tied to thermostat control issues
• HVAC service needs on vehicles with system-mounted thermostatic switch setups

Installation Notes and Tips

Verify the vehicle year, make, model, and HVAC configuration before installation. Fitment includes 1973-1995 Ford and Mercury applications, with notes for system mount and dealer-installed A/C expansion valve setups on specific Taurus models. Confirm the existing switch style and mounting arrangement against the original part before replacement. The part number SW3004C should be matched to the service application listed for the vehicle.

Quality Assurance

Universal Air SW3004C is cataloged for direct application matching in the listed Ford and Mercury HVAC systems. Confirm fitment by year, make, model, and system configuration before ordering.
