Why does the Mercedes-Benz AC light flash and then not light up?

If the car air conditioning AC light is not on and there is no cooling, it is likely due to a blown power fuse of the air conditioning switch, which fails to send a signal to the vehicle's compressor, thus preventing the cooling function from working. To fix this, replace the AC fuse located in the engine compartment fuse box; the position information is indicated on the box cover. Introduction to the AC button: The car AC switch controls the compressor when the air conditioning is in cooling mode. This function is available in both manual and automatic air conditioning systems. Whether manual or automatic, all air conditioning systems have an AC button. For automatic air conditioning, simply set the desired temperature, and the system will automatically select and open or close different air vents based on light sensors and multiple interior temperature sensors, adjust the airflow automatically, and turn on as needed. The role of AC: The AC button controls the air conditioning compressor. Some people may feel that turning on the AC makes the warm air for defogging colder, not only failing to warm up but also increasing the car's fuel consumption. However, in reality, many car models automatically turn on the AC when the windshield defogging function is activated. The reason is that AC has a dehumidifying function, which can speed up the defogging efficiency.
