What Causes One Side of Car Air Conditioning to Be Cold While the Other Side Is Not?

[StBrody]

Car air conditioning being cold on one side but not on the other is caused by issues with the air vents, malfunctioning air control flaps, or blockages in the air ducts. Air vent issues: If one of the servo motors for the air vents is damaged, it can result in one side of the air conditioning not cooling. Check the direction of the left and right air vents to observe whether the servo motor controlling the airflow on the right side rotates accordingly. Air control flap malfunction: A stuck air control flap can hinder the rotation of the flap, affecting the airflow on one side. Inspect the air door for any malfunctions. If the flap is stuck, it will obstruct its rotation, directly impacting the airflow. Air duct blockage: For automatic air conditioning systems, this issue may arise if the dual-zone control function is enabled. Simply disable the dual-zone air conditioning function to resolve the problem.
