Built to handle the switching behind your A/C and blower circuits, the Four Seasons relay, part number 35744, is a standard relay that lets a low-current control signal switch a higher-current circuit. It fits many vehicles, among them the 1991-1992 Chevrolet Caprice, 1991-1992 Chevrolet Commercial Chassis and 1995-1996 Buick Commercial Chassis, as a direct-fit replacement for the listed applications. See the "Vehicles it fits" section for the full list.
Depending on the application, it is listed for use as an A/C compressor control relay, an HVAC blower motor relay and a temperature control relay. Four Seasons engineers and tests its products and backs them with more than 50 years of mobile A/C experience.
- Precision engineered: Four Seasons describes the relay as precision engineered.
- OE-style molded connectors: the relay uses molded connectors styled after the OE design.
- Quality contacts: designed to provide proper conductivity through the switched circuit.
- Vehicle-specific applications: cataloged to specific vehicle applications.
Signs a relay may need replacing include an A/C compressor that won't engage, a blower motor that won't run or cuts in and out, or climate controls that respond inconsistently. Fuses, switches and wiring can cause the same symptoms, so diagnose the circuit first. If the relay is at fault, the 35744 replaces it.
