Why is there no air from the rear air conditioning?
1 Answers
The main reason for no air from the rear air conditioning is usually due to air leakage at the connection between the evaporator housing and the air duct. Air leakage at the connection between the evaporator housing and the air duct: If there is air leakage at the connection between the evaporator housing and the air duct, the cold air that should be released from the rear air conditioning vents will continuously leak from the gap, resulting in reduced airflow from the rear air conditioning vents. Issues with the cabin air filter: The cabin air filter is located at the air intake of the blower. All cold or hot air blown out by the car's air conditioning system must pass through the cabin air filter. However, the cabin air filter is prone to accumulating dirt. If the owner fails to replace the cabin air filter in time, it can easily become clogged with dust, leaves, dead insects, or even rodent remains. These obstructions naturally reduce the airflow passing through the cabin air filter, leading to decreased airflow from the rear air conditioning vents. Deterioration of the additional air duct seal: The rear air conditioning vents are connected to the blower via an additional air duct. If the seal of this additional air duct deteriorates, air leakage will occur, reducing the airflow from the rear air conditioning vents.
