5 Reasons Air Conditioning Not Working in Car

5 Reasons Air Conditioning Not Working in Car

The car’s air conditioning is formed by a sophisticated system that connects to the car’s electrical and other mechanical components in the vehicle. There are many reasons why the climate control in a car can stop functioning properly. Shall we identify a few of them?

Remember that, most of the time, even if you are able to identify the problem with your car’s air conditioning, it is still necessary to take it to the mechanic or auto electrician so that a prepared professional can carry out the necessary repairs.

Why is the car’s air conditioning not freezing?

  • clogged filter
  • Gas Leak
  • compressor lubrication
  • Electrical failure
  • system overload

Below we will talk a little about each of these recurring car air conditioning problems.

Clogged Air filter

Like any other air conditioning device, the automotive climate system also needs air filters to prevent impurities from being thrown into the air-conditioned environment. Even because, in cars, the air is collected directly from the street and all kinds of dirt can collect .

When the filter is too dirty or clogged, the air conditioning system fails to acclimate and stops working.

When and how to clean filters

Every 10,000 miles that the vehicle is driven, it is advised that the filters be cleaned. The procedure is simple: open the front hood, look for the filters—they should be right there, directly in front of the windshield—and then remove them.

The color of a good filter is white. If your filter doesn’t look like this, you need to wash it carefully, wait for it to dry and then you can put the piece back in place. If you can’t clean it, it’s best to buy another filter. 

Now, not everyone ventures to do this cleaning alone. All right, take your vehicle to a mechanic and ask for the filters to be cleaned, it’s a routine and low-cost operation.

Gas Leak

Car air conditioning also works with refrigerant fluid, which we call gas. It can happen that this substance leaks, and then there is no way for the equipment to do the air conditioning.

How to identify the leak

To identify a leak you can use soap and water . Mix the two together, open the hood and apply it to the air conditioning pipes, especially the connections. If air bubbles appear after a few seconds, there is a leak there. If you don’t feel safe testing it yourself, take it to a mechanic or auto electrician . 

What to do in case of a leak

If the leak is at the fitting, try screwing or threading more tightly on that end. If the leak is identified at another point in the pipeline, then professional weld repair is required. 

In both cases, the ideal is to replace the coolant, and that only a professional can do. Do not forget that, without the fluid or with less gas than indicated, the car’s air conditioning does not work or does not operate at its full capacity.

Compressor Lubrication

Always keep the compressor for the car’s air conditioning thoroughly greased. It simply won’t turn on if the lubrication runs go. Even though it can overheat and result in a dangerous accident.

It is advisable to occasionally turn on the car’s air conditioning to prevent this issue and keep the lubrication from drying out, keeping the compressor ready to function properly.

Simply visit the mechanic to get the lubricating fluid replaced if there is no lubrication.

Electrical failure

It can also happen an electrical failure in the air conditioning or car wiring. This is a more difficult case to identify and is usually only proven with a professional or after all other options have been tested.

System overload

Fans can’t operate when there is an electrical issue. The cooled or heated air is circulating in the air conditioner in this way, overtaxing the system and resulting in damage.

If you suspect an electrical failure, take your car for an evaluation and avoid using the air conditioning system so as not to aggravate the problem.

Identifying other problems

Other signs that your automotive air conditioner is having a problem are leaking lubricating fluid or oil. Every air conditioner forms a small runoff of water, but excess water can signal that the cooled air is being held elsewhere in the system. 

Always check for puddles forming just below the driver’s seat, or if the car leaves any shiny oil stains on the floor. All these are problems that need to be solved by trained professionals.
