Help keep the A/C compressor clutch and engine cooling fan switching on command with the Four Seasons Relay 36135, a standard relay listed as an A/C clutch relay, an A/C compressor control relay and an engine cooling fan motor relay. It fits many vehicles, among them the 2007-2011 Chevrolet Silverado 1500, 2010-2017 Chevrolet Equinox and 2007-2011 Chevrolet Silverado 2500, and it is a direct-fit replacement for the listed applications. See the "Vehicles it fits" section for the full list.
A relay is an electrically operated switch. A low-current control signal energizes it, and its contacts then close to carry the higher current that runs a load such as the compressor clutch or the cooling fan motor. If a failed relay is the reason a compressor clutch won't engage or a cooling fan won't run, this unit replaces it.
- Precision engineered: designed and tested by Four Seasons, which has more than 50 years of mobile A/C experience.
- OE style molded connectors: the connector design follows the original equipment style.
- Quality contacts: designed for proper conductivity through the switched circuit.
- Vehicle-specific applications: cataloged for specific vehicles rather than as a universal part.

Does it also fit the 2007-2011 Chevrolet Silverado 1500 or 2007-2011 Chevrolet Silverado 2500?
Yes. The 2007-2011 Chevrolet Silverado 1500 and 2007-2011 Chevrolet Silverado 2500 are among its listed applications. The "Vehicles it fits" section has the full list.
What does this relay control?
It is cataloged as an A/C clutch relay, an A/C compressor control relay and an engine cooling fan motor relay. It uses a small control signal to switch a higher-current circuit such as the compressor clutch or cooling fan motor.
What are signs this relay may need replacing?
Signs can include an A/C compressor clutch that won't engage, a cooling fan that won't run or won't shut off, or intermittent operation. Diagnose the circuit first, because fuses, wiring or sensors can cause the same symptoms.
How is this relay installed?
It connects to the vehicle's existing relay socket or connector. Consult the vehicle service information for the relay's location and for testing steps before you replace it.
