Keep your A/C and cooling-fan circuits switching as designed with the Four Seasons relay 35921, a standard relay that lets a low-current control signal turn a higher-current circuit on and off. It fits many vehicles, among them the 1983-1987 Dodge Charger, 1987-1988 Dodge Dakota and 1987 Dodge Grand Caravan, as a direct-fit replacement for the listed applications. See the "Vehicles it fits" section for the full list of vehicles.
Depending on the application, this relay is listed as an A/C clutch relay, an A/C compressor control relay or an engine cooling fan motor relay. Four Seasons draws on more than 50 years of mobile A/C experience and engineers and tests its products with the goal of years of trouble-free operation.
- Precision engineered: designed for vehicle-specific applications.
- OE-style molded connectors: connect to the vehicle's wiring harness.
- Quality contacts: intended to maintain proper conductivity each time the relay switches.
Signs this relay may need replacing 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 of either. Fuses, switches, sensors or wiring can also cause these symptoms, so diagnose the circuit first. If a failed relay is the cause, the 35921 replaces it.
