1. Why Is My Truck’s AC Not Blowing Cold Air?

There are numerous reasons why your truck’s AC might malfunction, ranging from simple to complex issues:

1.1. Low Refrigerant

This is the most common culprit. Refrigerant absorbs heat, cooling the air. If the refrigerant is low, the AC will be less effective or may not cool at all.

1.2. Dirty Cabin Air Filter

A dirty cabin air filter restricts airflow, preventing cool air from circulating properly throughout the vehicle. According to Mr. Nguyen Van A, a technician at Hyundai Truong Chinh truck dealership, the cabin air filter should be cleaned regularly or replaced every 10,000 – 15,000 km.

1.3. Blower Motor Issues

The blower motor circulates cool air throughout the cabin. If the blower motor is faulty, the cool air won’t be distributed evenly, resulting in inconsistent temperatures.

1.4. Faulty Condenser

The condenser releases heat from the refrigerant. If the condenser is dirty or damaged, its efficiency decreases, affecting the AC’s cooling capacity.

1.5. Refrigerant Leaks

The AC system can leak refrigerant from hoses, seals, or other components. When refrigerant leaks, the system won’t have enough to function properly.
