Why is there no air from the rear air conditioning?
2 Answers
Check if the valve of the rear air conditioning vent is closed. Relevant explanations are as follows: 1. Valve closure: Normally, the valve of the rear air conditioning vent should automatically open when the air conditioning is turned on. However, if the valve malfunctions, it may remain closed, preventing air from flowing through the rear air conditioning vent. 2. Air leakage: There might be air leakage at the connection between the evaporator box shell and the air duct. If air leaks from this connection, the cold air that should be released from the rear air conditioning vent will continuously escape from the leak, resulting in insufficient airflow from the rear air conditioning vent.
That time when I took the kids out for fun, I encountered the issue of no cold air in the back row. Later, upon inspection, I found that the rear air volume knob had been turned to the minimum by the mischievous kids. There's usually an independent control wheel above the rear air conditioning vents—make sure it's not completely closed. Also, check the air conditioning settings interface, as many cars require manually switching to simultaneous front and rear air supply mode. If it's the vent behind the center armrest, you might need to crouch down and feel if the air conditioning pipe has been kicked loose. Remember last month, a neighbor's MPV had no airflow because the pipe was blocked by a child seat—these hidden issues are particularly easy to overlook.
