What are the reasons for a car's electric fan not working?
1 Answers
There are several reasons why a car's electric fan may not be working, such as the coolant temperature not reaching the required level, a faulty relay, or a malfunctioning temperature control switch. Below is some relevant information about car electric fans: 1. Electric fan control methods: Unlike engine-driven fans, car electric fans need to adjust their operation based on the coolant temperature. Some are controlled by the vehicle's ECU, while others use a thermistor switch. Different cars have different electric fan control methods. 2. Structure: Generally, an electric fan assembly includes the electric fan, bracket, temperature sensor, temperature control switch, relay, wiring harness, etc. If the car's electric fan is not working, you can troubleshoot based on the above factors.
