This Dorman switch, the Dorman - OE Solutions HVAC Pressure Switch 904-612, is a direct replacement for the original A/C transducer switch, and when the A/C stops working, the cause could be as simple as the pressure switch. It fits many vehicles, among them the 2011-2024 Ford F-150, 2011-2024 Ford Explorer and 2011-2024 Ford Mustang. See the Buyer's Guide tab for the full list and engine details.
An A/C pressure switch monitors refrigerant pressure in the air conditioning system. Dorman lists this part as an air conditioning pressure sensor, and it is known by both names. If corroded terminals or a broken connector on the original switch are the problem, this switch replaces it.
Signs this part may need replacing include air conditioning that has stopped working, or corroded terminals or a broken connector on the original switch. Other A/C components can cause similar symptoms, so diagnose the system before replacing parts.
