Reasons why car air conditioner is not cool
Air conditioning is an indispensable equipment on cars in the upcoming hot summer days.
Many drivers often wait until the air conditioner breaks down or is not cold before repairing it. This is one of the reasons why the life and quality of the air conditioner decreases. In particular, regular maintenance and inspection of parts, especially the air conditioner, will significantly avoid problems that affect the engine.

Using air conditioning properly will help protect the engine and save a lot of fuel. |
According to experienced mechanics, when the car's air conditioner is not working properly, not cool or not cool enough, the driver can think of some of the following reasons:
The condenser is too dirty and cannot dissipate heat.
The condenser fan is not running or is running weakly. This phenomenon can be seen immediately.
The condenser coil is covered with thick dust, so the fan cannot blow air through it. This condition can easily lead to freezing of the condenser coil, making the car air conditioner unable to work.
A weak or broken compressor in the air conditioning system can also be the cause of the car's air conditioner not cooling.
The evaporator air filter is dirty.
The over temperature sensor is faulty or misadjusted.
Overcharge or undercharge.
The belt connecting the engine to the compressor is broken, the compressor clutch has a problem so when the switch is turned on, the compressor does not receive energy from the engine; the expansion valve is malfunctioning; there is a problem with the electrical circuit or a leak in the pipe causing the cool air to escape and not cool.
The above reasons all make your car's air conditioner work or not work but not cold enough.
In addition, when using the air conditioner, it should be adjusted to a moderate level to ensure a balanced amount of cool air in the car so as not to consume too much fuel. In particular, when getting out of the car, the temperature difference does not shock the driver.
