Hyundai Sonata Radiator Fan Relay Cooling Fan Relay Location How to test cooling fan relays low and high speed. Key points. recognize symptoms: engine overheating, poor a c, continuous fan operation, battery drain, risk of a c compressor damage. inspect for damage: check for corrosion, burnt marks, loose pins, cracked sockets in the relay. test functionality: use a multimeter, check for continuity resistance, listen for a click, inspect physically. Unplug the electrical connectors to the radiator fans. then turn your a c to the max position and start the engine. use a multimeter to check for power at the unplugged fan connectors. if you don’t see 12 volts at the connectors, the fan isn’t getting power from the relay. the fan relay is usually located near the bottom of the engine. The cooling fan kicks in and sends air flows to the engine. the air flows will continue until the sensor or ecm informs the relay that the temperature is normal again. then, the relay returns another electric charge to the radiator to switch off the cooling fan. with this, the relay is an intermediary between the sensor ecm and the radiator fan.
