How To Test A Cooling Fan Relay In A Car. Secure connections, prevent shorts, check power source, ground, and motor connections. A signal from the coolant temperature sensor is what triggers the ecu to turn on the radiator fan, and if it’s faulty, it can prevent the fan from working at all. Test the fan relay and fuses. First, ensure that the coolant level is adequate. Then, observe if the fan engages when the engine temperature rises. In this video i'll be showing you how to easily check your radiator fan and relay so you can diagnose over heating issues and bad. A faulty cooling fan motor relay can lead to engine overheating and inconsistent fan operation. Test the radiator fan with the engine running. If your engine is overheating, it’s crucial to check the radiator fan immediately. Check for corrosion, burnt marks, loose pins, cracked sockets in the relay. Testing low and high speed cooling fan relays. Since the relay operates as a switch for the fan’s power, a defective cooling fan relay won’t energize the circuit. Inspect the fan’s wiring and connections. Use a multimeter, check for continuity/resistance, listen for a click, inspect physically. Perform a continuity test on the fan motor.

How To Test A Cooling Fan Relay In A Car Test the radiator fan with a direct power source. Perform a continuity test on the fan motor. If the fan doesn’t turn on, this could be due to a faulty thermostat, sensor, or fan motor. The typical electric cooling fan circuit includes, a temperature sensor, a relay, a control module and the fan motor. Test the radiator fan with the engine running. Inspect the fan’s wiring and connections. Test the fan relay and fuses. Testing low and high speed cooling fan relays. Check for corrosion, burnt marks, loose pins, cracked sockets in the relay.
