What is the reason why the Audi A4 electric fan keeps running?
1 Answers
Audi A4 electric fan keeps running due to air conditioning compressor failure. Electric fan control method: Unlike engine-driven fans, automotive electric fans need to adjust their working status based on coolant temperature. Some are controlled by the vehicle ECU to operate the electric fan, while others use a thermistor switch. Different cars have different electric fan control methods. Composition structure: Generally, the electric fan assembly includes the electric fan, bracket, temperature sensor, temperature control switch, relay, wiring harness, etc. If the car electric fan does not rotate, the above factors can be checked for troubleshooting.
