Switch high-current circuits on command with the Four Seasons Relay 35988, a standard relay cataloged as an A/C compressor control relay, engine cooling fan motor relay and HVAC heater relay. It fits many vehicles, among them the 1991-1992 Ford Explorer, 1982-1983 Ford Mustang and 1985-1992 Ford Ranger, and is a direct-fit replacement for the listed Ford, Lincoln, Mercury and Jeep applications. See the "Vehicles it fits" section for the full list.
A relay is an electrically operated switch. A low-current control signal energizes its coil, which closes contacts that carry the heavier current to the circuit it serves. Depending on the application, that circuit can be the A/C compressor, the engine cooling fan motor or an HVAC heater circuit.
- Precision engineered: Designed and tested by Four Seasons, which draws on more than 50 years of mobile A/C experience.
- OE-style molded connectors: The molded connectors are styled after the original equipment.
- Quality contacts: The contacts are designed to provide proper conductivity through the switched circuit.
- Vehicle-specific applications: Cataloged for the specific vehicles listed in the "Vehicles it fits" section.
Signs this relay may need replacing include an A/C compressor, cooling fan or heater circuit that won't switch on, works only intermittently, or stays on. Wiring, fuses, switches and the component itself can cause the same symptoms, so diagnose the circuit before you replace the relay.
