Help your A/C compressor, cooling fan and HVAC circuits switch power on command with this Four Seasons relay, part number 35981. It is a standard relay listed as an A/C compressor control relay, an engine cooling fan motor relay and an HVAC relay. It is a direct-fit replacement for the listed applications, among them the 1980-1982 Toyota Tercel, 1979-1980 Toyota Land Cruiser and 1982-1984 Toyota Celica. See the "Vehicles it fits" section for the full list and engine details.
A relay is an electrically controlled switch. A small control current energizes it, and its contacts then switch the higher current that a component such as a compressor clutch or fan motor needs. If a failed relay is behind an A/C compressor that won't engage or a cooling fan that won't run, this unit replaces it.
- Precision engineered: Four Seasons engineers and tests this relay with long, trouble-free operation in mind.
- OE-style molded connectors: The molded connectors follow the original-equipment style.
- Quality contacts: Help maintain proper conductivity through the switched circuit.
- Vehicle-specific applications: The relay is cataloged for the listed applications and is backed by more than 50 years of Four Seasons mobile A/C experience.
Signs this relay may need replacing include an A/C compressor clutch that doesn't engage, a cooling fan that won't turn on or won't shut off, and intermittent HVAC operation. Fuses, switches and wiring can cause the same symptoms, so diagnose the circuit before you replace parts.

Frequently Asked Questions
Is this the right 1980-1982 Toyota Tercel relay?
Four Seasons 35981 is listed for the 1980-1982 Toyota Tercel. Check the "Vehicles it fits" section to confirm it matches your vehicle and engine.
Does it also fit a 1979-1980 Toyota Land Cruiser or a 1982-1984 Toyota Celica?
Yes. It is listed for the 1979-1980 Toyota Land Cruiser and the 1982-1984 Toyota Celica. See the "Vehicles it fits" section for details.
What does this relay do?
It is an electrically controlled switch. A low-current control signal energizes it, and its contacts then carry the higher current to circuits such as the A/C compressor clutch or cooling fan motor.
What are the signs of a failing relay?
A compressor clutch that won't engage, a cooling fan that won't run or won't shut off, or intermittent HVAC operation may be signs of a relay fault. Check fuses, switches and wiring too, since they cause similar symptoms.
How is this relay installed?
The relay has OE-style molded connectors. Follow your vehicle's service information to locate the original relay and replace it, including any battery-disconnect steps it calls for.
