Why Isn't The Air Conditioning In My Car Working?

Did you start your car?

Near the dashboard, there is a fan dial. Is the dial been set to zero?

Has the AC button been pushed and the light indicator turned ON?

Have the flaps on the air vents been opened?

Are you using the vehicle's AC after a long period of inactivity?

When you turn the AC on, do you feel a slight vibration or buzzing sound for a small amount of time?

Did you fill the refrigerant gas in the past year or two?

Did you refill the refrigerant gas multiple times in a period of just a few months?

A car needs to be powered up first in order to run the AC.

The fan dial is basically a speed control and a secondary power switch. So to turn the AC on, you have to turn the dial first.

The AC button is the primary power button for the AC which when pressed will turn the AC on.

Open the vents in order to let the air out. You can also open selective vents if you are the only person and driver in your car to get better air flow.

The issue most probably is with a faulty condenser as they stop working after not being used for some time. Get the condensers checked and replaced if necessary.

This either means that the electric relay for the AC is faulty or that the fuse for the condenser is broken. Take your car to a professional technician and ask to check the vehicle's internal electric system.

Most cars need to have refrigerant gas filled in the condenser tank on yearly or bi-yearly basis, so make sure to refill the gas as soon as you can.

This most likely is due to a leak or multiple leaks in the condenser. Get the condensers checked and replaced if necessary.

It is possible that the problem has to do with the internal electronics in the vehicle. Take your car to a professional technician and ask to check the vehicle's internal electric system.
