System Components:

Can you fix things without knowing how they work? You can’t. That is why here is a list of the components and how they work to make it easier.

  • The refrigerant

The refrigerant is important to the AC system as it is responsible for making it cool and carrying the heat. It is mostly referred to as R134 in newer cars and the older ones the term 12 freon.

  • The compressor

Where there’s a coolant there has to be a compressor as it is responsible for compressing and transmitting the coolant.

  • The condenser

The condenser is responsible for ejecting the heat out of the car and also changing the state of the coolant into gas (liquid and gas).

  • The expansion valve

The purpose of this component is to reduce the coolant pressure.

  • The evaporator

This sends the heat to the refrigerant and keeps the car cool.

  • The dryer

Staying true to its name, it acts like a filter and removes dampness and other unpleasant substances from the refrigerant.


Now that you know the basic structure and components, it’s time to learn how to fix the AC if it’s ever broken.

  • Coolant

If Low cooling is a sign of the disfunction AC the solution to that will be adding more coolant but be careful not to overfill it as instead of boosting your car’s performance it will slow it down.


Leaks can prevent heat from being expelled out of the car and that is a malfunction. To fix this, might be hard but once you get the hang of it, it’s quite easy. Fluorescent dye can be found at stores and can be poured in case it’s a major leak go to a maintenance shop

  • Compressor Problem

Lastly, the compressor’s performance. For this turn on the AC and check under the hood the structure should be similar to a bike’s outer pulley and chain. If the the wheel spins then the AC works fine if not then get it fixed.

  • Problems with the electrical system


The A/C system in your car has a maze of wires complete with fuses, relays, and pressure switches that work in unison to provide safe operation under normal operating conditions. If one of these electrical components fails due to age or defect, the system is designed to shut itself down to prevent damage to itself or unsafe conditions for the operator. Without the proper test equipment and, perhaps more importantly, the experience level of the individual diagnosing the problem, these issues are difficult to isolate.
