What is the reason for the failure of the BYD S6 air conditioning switch?
2 Answers
BYD S6 air conditioning switch failure is caused by a damaged air conditioning fuse or a faulty air conditioning circuit board. Below is a detailed introduction about car air conditioning: 1. Overview: The car air conditioning device (air-conditioning-device), referred to as car air conditioning, is used to adjust and control the temperature, humidity, air cleanliness, and air flow inside the car cabin to the optimal state. 2. Function: It provides a comfortable riding environment for the driver, reducing travel fatigue; it creates good working conditions for the driver, ensuring driving safety. The car air conditioning system typically includes a refrigeration device, heating device, and ventilation device.
My BYD S6's AC buttons weren't responding, and it took me days to figure it out. There are typically three common issues: either the AC panel buttons themselves have poor contact (when opened, they're often full of dust); or the wiring connectors are loose, especially the large wiring harness under the driver's seat which can loosen over bumps; or the fuse is blown—you'll find the AC fuse in the fuse box under the steering wheel. I once saw a case where the control module failed, which required a computer diagnostic. If you can't pinpoint the issue, try disconnecting the negative battery terminal for five minutes to reset the system—this little trick can sometimes resolve electronic glitches.
