Switch power to high-current circuits on a low-current signal with the Four Seasons relay, part number 36148. This standard relay is listed as both an engine cooling fan motor relay and an HVAC system relay. It fits many vehicles, among them the 1989-1995 Mazda RX-7, 1994-1998 Mazda MPV and 1992-1994 Mazda 929, and 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 small control current energizes it, and its contacts open or close a higher-current circuit, such as one that feeds a cooling fan motor or an HVAC component. Four Seasons engineers and tests the 36148 and brings more than 50 years of mobile A/C experience to it.
- Precision engineered: made for vehicle-specific applications.
- OE-style molded connectors: molded in the style of the original equipment connectors.
- Quality contacts: intended to provide proper conductivity through the switched circuit.
- Vehicle-specific applications: cataloged for the listed Mazda and Mercury applications.
Signs this relay may need replacing: a cooling fan or HVAC function that won't switch on, works only intermittently, or won't shut off. If the relay is the cause, this part replaces it. Check the fuses, wiring and the component itself before you replace the relay.
