What causes the rear air conditioning in the Wildlander to have no airflow?

[WillowLee]

The lack of airflow from the rear air conditioning in the Wildlander may be due to air leakage at the connection between the evaporator case and the air duct. The cold air that should be released from the rear air vents is continuously leaking from the gaps, resulting in reduced airflow from the rear vents. Issues with the cabin air filter: The cabin air filter is prone to accumulating dirt. If the owner does not replace the cabin air filter in time, it can easily become clogged with dust, leaves, insect remains, or even rodent carcasses. These obstructions naturally reduce the airflow passing through the filter, leading to decreased airflow from the rear air vents. Deterioration of the additional air duct seals: The rear air vents are connected to the blower via additional air ducts. If the seals of these ducts deteriorate, air leakage can occur, resulting in reduced airflow from the rear vents.
