Put a fresh relay in charge of switching the air conditioning circuit with the Standard Ignition A/C Relay RY-200. It installs as a direct-fit replacement for the 1979-1982 Nissan 310 and the 1977-1979 and 1981 Nissan 810. See the Buyer's Guide tab for engine details.
A relay lets a small control current switch a heavier electrical load, so the switch or control circuit does not have to carry the full current itself. This part is listed under several names: A/C relay, accessory power relay, engine cooling fan motor relay and HVAC relay.
Signs this relay may need replacing include an A/C system or fan that won't switch on or works only intermittently. Another sign is a relay that clicks without powering its circuit. Fuses, switches and wiring can cause the same symptoms, so diagnose the circuit before replacing the relay.
