What should I do if the air conditioner in He Yue is sometimes cold and sometimes not?

1, if it is a sedan, then 90% is the problem of the central control panel of the air conditioner.

2, if it is a hatchback, it is divided into two situations;

A. When the engine is running and the air conditioner is turned on, the air conditioner does not cool. Check whether the compressor of the air conditioner works first (you can also feel whether the low-pressure pipe of the air conditioner is cold). If the compressor is working or the low pressure pipe is cold, there must be something wrong with the indoor temperature sensor or the mixed gas servo motor of the air conditioning system.

B, if the compressor is not working or the low pressure pipe is not cold, it is recommended to replace the outdoor temperature sensor.
