WrenchConnect diagnosis problem signals
A leak in the AC system can result in low refrigerant, preventing the system from absorbing heat and cooling the cabin air.
Leaves, dirt, or road debris can block the fins of the AC condenser at the front of the vehicle, restricting the airflow needed to cool the refrigerant when the car is not moving.
The AC compressor may be wearing out and failing to pump refrigerant efficiently at lower engine speeds, though this is less common on a relatively newer vehicle.
The compressor or its clutch may not be engaging properly, preventing the refrigerant from circulating through the system.
