If the air conditioning in the Trumpchi GS4 is not cooling or blowing cold air, first check whether the A/C button has been pressed to activate the cooling system. Next, verify if the fan speed and temperature settings are at their minimum values. If these issues are not the cause, the problem might be due to the following reasons: 1. Refrigerant: Insufficient refrigerant. 2. Heat dissipation: The radiator and condenser are crucial components for heat dissipation in the vehicle. If they are excessively dirty, it can lead to poor heat dissipation, which not only causes the engine to overheat but also directly affects the cooling efficiency of the air conditioning. 3. Blower motor malfunction or damage: The blower motor is the power source for the air conditioning's airflow. If there is an issue, the air conditioning may not blow air. To check if the blower motor is damaged, owners can turn on the air conditioning at maximum fan speed and listen to the blower motor's location in the vehicle to determine if it is functioning or if there are any obstructions inside. 4. Air conditioning filter: The air conditioning filter's role is to prevent dust from entering the cabin. Over time, the filter can accumulate dirt, develop odors, or even become clogged. When the filter is blocked with dust and debris, it severely impacts the airflow of the air conditioning. This can result in high fan speed settings producing loud noises but delivering very little actual airflow, significantly reducing the cooling effect.
