What are the Causes Behind the Impaired Car Heater and AC?

On hot summer days, the car is getting hot after it has been parked in the hot sun for the whole day. But modern cars have the climate control system or air conditioning system to keep your ride comfortable on the road during the daytime. Apparently, on the chill evening the heater plays an important role to clear the fogged up windshield quickly.

When the heater or the A/C system is not functioning in your car properly, then you will get the worst experience ever. To fix the heater and AC issues of the car, you have to determine the causes behind it. Here are the points that define the common reasons behind the affected climate control system of the car.

Damaged blower motor

The main function of the AC system in your car is to pull the warm air as well as the humid air from the cabin and replace them with cool and dry air. The blower motor which is a simple fan of the car is responsible for pushing the air through the climate vents behind the dashboard. If the blower motor of the car has any problem, then no cool air will flow through the vents.

Cracked heater core

Just like the radiator of the car, the heater core also cracked over time due to corrode, rust and clog inside it. Moreover, the outside air brings debris such as dirt, leaves, dust, and road grime and enters into the climate system to clog it. Thus, the heater core is clogged with the debris on the outside, so it needs replacement immediately. As a result, it will lose its ability to exchange heat. For preventing cracked heater core issues, you simply need to clean it.

Leaked refrigerant

In the AC system, the refrigerant gases are stored for cooling the air which is entering into the cabin. But over time, the small wear in the seals, AC compressor, hoses, and AC condenser cause a leak. If you notice that the AC system of your car is working well, but doesn’t blow cold air as it did before, then ensure that it has a low running refrigerant. When the refrigerant leaks from your car badly, it will blow the hot air from the AC system downright into the cabin.

Depressed coolant level

In a car, the coolant flows through the engine to absorb the heat from its moving parts. Subsequently, it can flow to the radiator for exchanging the heat with the outside air and allow them to cool down and get back to the engine. The cooling system of the car is responsible for keeping the engine cool. But a small problem with the cooling system may affect the performance of the heater or somehow block it.

When the heater core is damaged, it is unable to exchange the heat with the outside air and sends hot air to the blower motor through the climate vents. As a result, you will experience a warming cabin. Throughout the process, you just need to top off the coolant system for fixing the problem.

Broken AC compressor

The AC compressor is defined as the centerpiece of the car’s air conditioning system because it can promote the refrigerant gas to flow through the system. If the AC compressor is broken, then it will be unable to perform its functions efficiently. Apparently, the AC compressor of the car was also damaged due to its broken internal components.

If you notice any types of damages or wear out in any components of the AC compressor, replace it as soon as possible by consulting with a reputed mechanic. The major drawback of a broken AC compressor is, it can send bits of metal throughout the system that need immediate inspection. If you neglect the issues, then it may lead to bigger problems and damage other parts of the cooling system.

Conclusion

If you want to protect the climate control system of the car properly, then consider the above-defined points for better understanding. By taking the necessary steps, you can prevent the damages that arise in the heater core and AC system of the car. Consult with a reputed and trained mechanic for fixing the issues if it arises in the middle of the road.
