A relay is an electrically operated switch. A low-current signal energizes its coil, which closes internal contacts to send power to a higher-current circuit, such as the compressor clutch or the blower motor. If a failed relay is the cause of your A/C or blower trouble, this unit replaces it.
- Precision engineered: built for vehicle-specific applications.
- OE-style molded connectors: molded connector design in the style of the original.
- Quality contacts: help ensure proper conductivity through the switched circuit.
- Mobile A/C experience: engineered and tested by Four Seasons, which has more than 50 years of experience in mobile A/C.
Signs a relay may need replacing include an A/C compressor clutch that won't engage, a blower motor that doesn't run, or on-and-off operation. Diagnose the circuit before replacing the relay. Fuses, switches, wiring and the powered components themselves can cause the same symptoms.
