Fan Relay Is Not Working at Renato Layton blog

Fan Relay Is Not Working. There are three ways to check for a bad terminal. It can also be caused by a faulty coolant temp sensor, low. However, a bad fan motor, a malfunctioning ecm, or wiring. The cooling fan relay is normally located in either the underhood fuse and relay center or mounted to the electric fan assembly. The fasted way to tell whether or not the electric fan(s) are working is, to start the engine. The most common causes of why a radiator fan is not working are a blown fuse, a bad relay, or a broken wire. Then, let it reach normal operating. First, note that the relay has four terminals: In most cases, a blown fuse or bad starter relay is responsible for a vehicle's radiator fan not turning on. Engine overheating, poor air conditioning performance, and the fan running continuously and draining the battery are all signs that your relay may be faulty. The radiator fan switch relay may not be supplying power to the fan. Two control terminals and two power terminals. If your vehicle’s cooling fan relay is failing, you may notice several common symptoms indicating potential issues. If necessary, a replacement relay costs around $20. Since the relay operates as a switch for the fan’s power, a defective cooling fan relay won’t energize the circuit.
