Possible Reasons Why Your Car AC Is Not Working

- Checking for leakage in the refrigerant can avoid episodes of hot air.
- Debris can clog and lead to the malfunctioning of coolant fans
- Huge repair investments would be required for electrical circuit issues
A leak in the refrigerant is the major reason that causes hot air issues in the coolant system. Other probable reasons like electrical system issues, faults in the condenser, and worn out coolant fans are some of the major reasons that lead to the cause of the warm air blown out by the air conditioning system of the car. In this article, we will discuss the five major issues along with solutions that can restore them.

Have you ever wondered why the air conditioning system in a car gives out warmer air?
To know that, let's see what the air conditioning system is made of. The air conditioning system in the car comprises a compressor, a condenser, a dryer, an expansion valve, and an evaporator. Any failure in the working efficiency of these systems can lead to a problem where cooler air gets warmed enough to heat everything in a few moments. Let's now discuss the five reasons that put off the cooling system.
01. Leaking refrigerant

The refrigerant has an automatic recycling mechanism, and it can only cause problems if there is a leak in the system. And the first sign is the warm air blown from the pane. As the leak occurs in a gaseous state, it will be problematic to find the exact spot where the leakage is occurring. It can be solved by either replacing the worn-out parts, or if it's a minor leak, it can be solved by using a leak sealer.
02. Malfunctioning Condenser

A condenser removes heated air from the system and blows it outward. If there is a malfunctioning condenser, then there is no doubt that the system bursts hot air. The possibility of debris clogging in the condenser is a probable reason, and clearing the obstructed clutter proves to be a beneficial restoration, but if the defect is worse, then replacing the part would be the ideal alternative.
03. Electrical System Issues

The functioning system runs on the feed of electricity. If the circuit has broken wires or damaged parts that cut the power supply, it would lead to the problem of heatwaves. The only way to work out the problem is by solving the wiring system with the rewiring of an electrical circuit.
04. Cooling Fan Issues

Debris clogging or blown out fuse issues may lead to malfunctioning of the two coolant fans in the condenser, which may eventually lead to warm air issues. The only solution to this problem is to replace the deteriorated fans.
05. Faulty Compressor

The function of compressors is to compress the low-pressure and low-temperature gases into high-pressure and high-temperature gases that eventually reach the refrigerant. Due to lack of use for longer periods, the sudden usage may shock the circuit system, which makes it wear out sooner. The ideal and only solution is to repair the damaged part because it has many moving parts. Try to run the air-conditioning system for a few minutes a week to avoid the problem, which will prolong the life of the coolant system.
