It fits many vehicles, among them the 1992-1994 Dodge Grand Caravan, 1992-1994 Dodge Caravan and 1986-1988 Chevrolet Monte Carlo. See the "Vehicles it fits" section for the full list and engine details.
A relay is an electrically operated switch. A low-current signal from the control circuit energizes it, and its contacts close to carry the higher current the fan motor or heater circuit needs. If you need a 1992-1994 Dodge Caravan relay or the matching part for another listed vehicle, this unit is a direct-fit replacement for the listed applications.
- Precision engineered: Four Seasons engineers and tests its products and brings more than 50 years of mobile A/C experience to them.
- OE-style molded connectors: The relay connects through OE-style molded connectors.
- Quality contacts: The contacts are designed to help maintain proper conductivity through the switched circuit.
- Vehicle-specific applications: The relay is cataloged for the specific vehicles shown in the "Vehicles it fits" section.
A relay may need replacing if the cooling fan or heater circuit does not turn on, runs when it should not, or works only some of the time. Fuses, wiring, switches and motors can cause the same symptoms, so diagnose the circuit before replacing parts. If the relay is the cause, this unit replaces it.
