Having a non-functional AC can be a menace. Your car may not be blowing cold air for many different reasons. Recharging your car's AC refrigerant or repairing a refrigerant leak might fix the problem, but more complex electrical climate control repairs or a slipping compressor clutch may be necessary for restoring full air conditioning performance. The air conditioning system in your car may be complicated because of the location of the hoses and lines. Your car's air conditioning system compresses and heats the refrigerant before allowing it to decompress and condense into a liquid, causing it to lose heat quickly. To get the desired temperature, you must repeatedly repeat the process of absorbing heat from the car's interior.
We have compiled some of the top reasons why your car won’t blow cold air. Let’s dig in.
1. Mold Buildup
Keeping the AC turned on for a longer period of time can result in the growth and buildup of mold. Microorganisms have the capacity to block the AC vents. The bacteria can block the AC vent, which affects the working of the AC. Normally, when this happens, you can’t do much about it. This is one of the reasons your AC is not properly cooling the cabin. Getting a regular service removes the AC duct and the dust particles and avoids any mold buildup. This hygienic solution improves the durability of your car.
2. Electric Issues
There might be an unwanted short circuit in the electrical unit that is the cause of your non-functional AC. It is a common scenario in vehicles these days. If you live somewhere where the temperature goes beyond 45 degrees, the wires get heated up, causing a short circuit in the internal wiring.
3. Faulty Cabin Filter
The air that gets into the vehicle’s air conditioning system is filtered by a cabin air filter. The filter gets clogged with all the dust and contaminants that enter that area. A clogged cabin filter makes the air filter less efficient. For the efficient working of the AC, it is advised to inspect it regularly and replace the cabin air filter.
4. Your Air Car Needs a Recharging
No matter how great an air conditioner you have, it will still lose a little refrigerant with the passage of time. The process is often so slow that you won’t even notice a difference. It may be difficult for you to realize that you might have a degree or two of difference in your A/C temperature. It might be that you are low on Freon. It is one of the most common reasons for the A/C not blowing cold air. You can tell if your A/C leaks. If the refrigerant level is low, the A/C can be recharged.
5. Refrigerant Leak
The leakage in the refrigerator is another reason your AC to not work properly. The refrigerant keeps the cabin cool. In most cases, the leakage of the refrigerant causes the car to malfunction. This can happen when your car has an unexpected accident. The AC hose leaks at the joints. It gets really difficult to identify where the damage is done. The oily material around the hose indicates leaking. The refrigerant needs to be fixed in this scenario.
6. Blocked/Condensed Condenser
The next reason your AC is not blowing cold air is a blocked/condensed condenser. It is the unit responsible for keeping the refrigerant cool, which then goes through the blower by converting the hot air into cool air. The air is blown through the AC vents located in front of the grille. If there is any problem, the grill is easy to identify, and the problem can be fixed. Having a blockage or debris overheat the car. The heated air may damage your car if it is not taken into consideration. It causes a significant load on the car's AC engine, which eventually affects the air cooler of your vehicle. So you need to be careful.
The wise decision is to take the car to a professional car repair center that’s authorized to repair similar car models.
7. Dysfunctional Air Conditioning Unit
You may have a dysfunctional air conditioning control unit. A wrong signal is given to the blend door actuator when the air conditioner's control unit does not work properly. This results in the blowing of hot air instead of cool air.
8. Damaged Condenser Fan
Heat gets transferred from the evaporator through the condenser installed at the front of the car. The AC condenser is installed in front of the radiator, making the radiator prone to damage from flying stones and other objects. This causes the AC refrigerator to leak, which then flows out.
9. AC compressor clutch failure
Inside certain car compressors, there's a crucial component known as the clutch. When you turn on the air conditioning in your car, this clutch comes into play, connecting the air compressor to the pulley. The pulley is powered by the serpentine belt, and this connection makes the AC compressor spin, thus powering the entire AC system.
However, there's a problem if this clutch becomes too worn out. In such cases, the AC compressor may not even turn on, leaving you without any air conditioning. The good news is that many AC compressors allow for adjustments. You can either replace the clutch or simply remove some shims to make the clutch work a bit harder, restoring its functionality and getting your AC system back in working order.
