Peugeot 408 air conditioner does not heat.

What is the reason why Peugeot 408 doesn't dissipate heat? There are many reasons why the air does not cool down, and the most common ones are: 1. If there is no air or the air volume is small, it is necessary to check whether the air filter element is dirty, whether the blower can operate normally and whether the air copying motor can be turned on and off normally; 2. Freon in the air conditioning system is missing, so it is necessary to check whether the system leaks. After the maintenance is confirmed, add freon to the standard range; 3. The water tank condenser is dirty, and the engine cooling system fails, resulting in high water temperature. For example, the cooling fan does not work, resulting in poor cooling of the water tank and condenser. 4. The data of sensors such as air pressure adjustment sensor and evaporation box sensor are wrong, which leads to incorrect adjustment of air conditioning system; 5. The air-conditioning compressor solenoid valve is damaged, the air-conditioning compressor clutch is damaged, and the air-conditioning compressor is damaged internally; 6. The empty system circuit or control unit is faulty. When the car is not cooled, you can choose a relatively professional maintenance organization for inspection and maintenance. For example, the 4S shop or brand shop of this model brand should choose the maintenance organization according to its actual situation.
