involves models: automatic air conditioning equipment Chery A3 sedan.
Bulletin contents: In the case where the air conditioner turned off (OFF knob wind speed), if there is air conditioning control panel automatically turn on (i.e., A / C compressor automatically turns on or lights, the blower works automatically), belongs to the anomalies, may consider replacing the air conditioning control panel. If the control panel buttons malfunctioning part, recommended a restart and then check the function of the vehicle air conditioning off (disconnect the battery), the problem goes away if you do not need to replace the air conditioning control panel. Further, the electric air conditioner control panel where A / C compressor or indicator light automatically automatic operation does not occur.
air conditioning control panel
In order to prevent service personnel do not understand the A3 sedan automatic air conditioning function to produce false positives, air conditioning now the following features will be described below (under the conditions of air conditioner turned on, i.e. not in the OFF knob wind speed).
(1) When the mode dial in the AUTO block, the air conditioning system enters the automatic control, the control unit on or off according to the current exterior and interior temperature control air conditioning compressor. Note that, at this time if the mode dial position and then turned to the other, the compressor control remains in automatic control mode, unless manually press A / C switch or changing the state of the air volume, the air conditioning system exits the automatic control mode.
(2) rapid cooling, heating function (New)
① automatic climate control: when the temperature set by the temperature dial when set to 18 ℃, automatically turn on the compressor, A / C indicator lights, air circulation is switched into the loop, the outer loop is switched to a period of time; when the temperature set by the temperature dial to the compressor and the current in 32 ℃ automatic control state, the compressor will automatically close, A / C indicator is off, the air circulation is switched to the loop, the outer loop is switched to a period of time.
② electric air conditioner control: when the temperature was adjusted to the hottest or coldest state, air circulation will automatically switch to the loop, the outer loop is switched to a period of time.
(3) Special Description: A / C indicator is only a hint of the representative control target. Normally, A / C compressor with the same indicator display state, the compressor is operating but also associated with other conditions. For example, A / C indicator lights, if the evaporator temperature or the ambient temperature is too low, the compressor does not work, which is the normal protective function of the compressor is not a malfunction. When the battery voltage is too low, the air conditioning system has a low-voltage protection function, the air conditioning system does not work, this is normal.
