Keep your A/C compressor clutch cycling as designed with the Four Seasons switch 35856, a system-mounted A/C Clutch Cycle Switch / Thermostatic Switch with a preset cycling temperature. It fits many vehicles, among them the 1968-1972 Ford F-250, 1968-1972 Ford F-100 and 1968-1972 Ford F-350. See the Buyer's Guide tab for the full list.
A thermostatic cycling switch senses temperature and turns the A/C compressor clutch on and off, helping keep the evaporator from icing up while the system runs. This unit's cycling point is preset, and it is listed under both names: A/C clutch cycle switch and thermostatic switch.
- OE-style connectors: Built with OE-style connectors.
- Quality contacts: Quality contacts are designed for proper conductivity.
- Sealing components included: Comes with the gaskets, O-rings or seals needed to properly replace the product.
- Precision engineered: Engineered and tested by Four Seasons, backed by more than 50 years of mobile A/C experience.
Signs this part may need replacing: a compressor clutch that will not engage, cycles on and off rapidly, or never cycles off, along with icing or weak cooling. Other A/C faults can cause the same symptoms, so diagnose the system before replacing. If a failed cycling switch is the cause, the 35856 replaces it.
