Help keep your A/C compressor clutch cycling at the proper temperature with this Four Seasons switch, part number 35715, an A/C Clutch Cycle Switch / Thermostatic Switch with a preset cycling temperature. It fits many vehicles, among them the 1972-1973 Ford Mustang and the 1972 Ford F-250, as a direct-fit replacement for the listed applications. See the Buyer's Guide tab for the full list and engine details.
Listed under both names, this system-mounted switch senses A/C temperature and switches the compressor clutch on and off at its preset point. That cycling is designed to help keep the evaporator from icing over while the system runs.
- OE-style connectors: the connector is styled after the original design for the wiring connection.
- Quality contacts: intended to maintain proper electrical conductivity.
- Sealing components: supplied with the gaskets, O-rings or seals needed to properly replace the switch, as applicable.
- Precision engineered: Four Seasons engineers and tests its products for trouble-free operation, drawing on more than 50 years of mobile A/C experience.
Signs this switch may need replacing include a compressor clutch that will not engage, cycles erratically or stays engaged, frost on the evaporator with reduced airflow, or warm air from the vents. These symptoms can have other causes, so diagnose the A/C system first. If a failed cycling switch is the cause, this part replaces it.
