The main reasons for no air coming out of the air conditioning in the new Corolla are as follows: Blower failure: The blower is the core component for air conditioning airflow. If it malfunctions, there will definitely be no air output. Possible causes of blower failure include overheating damage to internal coils or capacitor failure. Owners can determine if there is a malfunction by turning the car's air conditioning fan speed and air volume to maximum and listening for the blower's sound. Clogged air filter: A clogged air filter is the most common cause of no airflow in the air conditioning system. Outside air passes through the air filter before entering the vehicle, and it also traps many airborne particles, making it prone to clogging. The air filter can be removed for inspection. If it's not too dirty, use an air gun to clean the debris before reinstalling it to check if the air vent issue is resolved.
I've repaired my own car before, and the common causes for no air from the AC are a faulty blower motor or a blown fuse. As a DIY enthusiast, I would first open the engine compartment to check if the relevant fuse in the fuse box is burnt out. If the fan can still spin but there's no airflow, it might be due to stuck fan blades or a clogged cabin air filter blocking the vents. The new Corolla has many electronic systems, and occasionally you might encounter issues like a faulty AC control switch or a relay malfunction, preventing the signal from reaching the fan. It's recommended to clean the filter regularly to avoid dust buildup affecting airflow. Driving without AC in summer is unbearable, so if the problem persists after checking, seek professional diagnosis promptly to avoid affecting the cooling system. Be cautious of electric shocks when doing repairs yourself, and for newer cars still under warranty, it's best to contact the dealership.
