It activates or deactivates the compressor clutch based on pressure readings, protecting the system from damage due to excessively high or low pressure. The switch features a robust housing made from plastic and steel, ensuring longevity under demanding conditions. Its four male blade terminals and black square connector provide secure electrical connections, while the screw-on mount with a 10 mm thread diameter allows for straightforward installation. This pressure switch is specifically engineered for vehicles using R134a refrigerant and operates reliably within the pressure limits of 230 psi (closed) and 435 psi (open), withstanding pressures up to 600 psi.\u003c\/p\u003e\u003ch2\u003eCompatible Vehicles and Common Applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eFord Crown Victoria HVAC pressure switch replacement\u003c\/li\u003e\n\u003cli\u003eHVAC pressure switch for Ford F-250 and F-350 Super Duty models\u003c\/li\u003e\n\u003cli\u003eLincoln Town Car and Mercury Grand Marquis air conditioning system maintenance\u003c\/li\u003e\n\u003cli\u003eReplacement part for Ford Escape, Excursion, and Mariner HVAC systems\u003c\/li\u003e\n\u003cli\u003eEnsures proper compressor operation in Ford Mustang and Taurus models\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eEnsure the vehicle’s air conditioning system uses R134a refrigerant before installation\u003c\/li\u003e\n\u003cli\u003eDisconnect the battery and relieve system pressure prior to removal\u003c\/li\u003e\n\u003cli\u003eUse appropriate tools to unscrew the old pressure switch from the mounting point\u003c\/li\u003e\n\u003cli\u003eVerify the 10 mm thread diameter matches the mounting location\u003c\/li\u003e\n\u003cli\u003eConnect the four male blade terminals securely to avoid electrical issues\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eQuality Assurance and Warranty Information\u003c\/h2\u003e\u003cp\u003eDorman parts are manufactured to meet or exceed OEM specifications, providing reliable performance and durability.
