Failing Coolant Fan Switch at John Janssen blog

Failing Coolant Fan Switch. And, is therefore an important electrical. But the problem may not only be that the fan does not turn on, but that it can not be turned off; If your vehicle’s cooling fan relay is failing, you may notice several common symptoms indicating potential issues. Since the relay operates as a switch for the fan’s power, a defective cooling fan relay won’t energize the circuit. A faulty cooling fan motor relay can lead to engine overheating and inconsistent fan operation. 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. The cooling fan relay essentially functions as, the switch for the engine’s cooling fans. 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 fact is that the rupture of the electrical circuit. This is a characteristic symptom of a relay failure. Without it, the cooling fan won’t work. The cooling fan relay is an electromagnetic switch that controls the power supply to the engine’s cooling fans.
