Designed to switch power in A/C compressor, engine cooling fan or HVAC circuits, the Four Seasons relay, part number 36198, is a standard relay built for vehicle-specific applications. It fits many vehicles, among them the 2007-2012 Mazda CX-7, 2009-2010 Mazda MX-5 and 2009-2010 Mazda MX-5 Miata, as a direct-fit replacement for the listed applications.
Depending on the application, the 36198 is cataloged as an A/C compressor control relay, an engine cooling fan motor relay and an HVAC system relay. A relay is an electrically controlled switch. A low-current signal energizes its coil, which closes contacts that carry the higher current the circuit needs.
- Precision engineered: built by Four Seasons, which draws on more than 50 years of mobile A/C experience.
- OE-style molded connectors: molded connectors in an OE style for the listed applications.
- Quality contacts: help maintain proper conductivity through the switched circuit.
- Vehicle-specific applications: matched to the listed Mazda models. See the "Vehicles it fits" section for the full list.
Signs a relay may need replacing include an A/C compressor that won't engage, a cooling fan that won't run, runs constantly or works only intermittently, and HVAC operation that cuts in and out. Fuses, wiring, sensors or the components themselves can cause the same symptoms, so diagnose the circuit first. If the relay is the cause, the 36198 replaces it.
