It is a specific-fit component with a round black connector, metal housing, and 2-pin electrical interface. The switch is intended for R134A refrigerant systems and uses a bolt-on mounting style with a 10 mm thread diameter. If the original switch has corroded terminals or a broken connector, this replacement helps restore the pressure signal needed for normal air conditioning operation. This part cross-references Baldwin 20053 for the same application.\u003c\/p\u003e\u003ch2\u003eCommon Issues This Part May Address\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eAir conditioning stops cycling or responding correctly\u003c\/li\u003e\n\u003cli\u003eCorroded pressure switch terminals\u003c\/li\u003e\n\u003cli\u003eBroken or damaged original connector\u003c\/li\u003e\n\u003cli\u003eFaulty A\/C pressure signal at the HVAC control circuit\u003c\/li\u003e\n\u003cli\u003eLoss of cooling performance tied to switch failure\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eVerify the vehicle uses an R134A system and confirm connector style, thread diameter, and mounting style before installation.
