2. See whether the compressor is working or not.

The next thing that you need to check is whether the compressor is working or not.  For this you first need to find the air conditioner in the engine bay and then check if the pulley and its center are turning along together. In the cases when the air conditioner is working fine, a clutch engages and the centre of the pulley will turn along with the pulley. If not, then the compressor may be faulty or broken and may need replacement. In some cases, filling refrigerant in it can also do the trick and solve the issue.
