Is it a central unit? check and see if the fan and compressor are running in the outdoor unit. The system may be low on freon or the compressor may not be running. It is best to call a qualified HVAC technician.
it's an air conditioner because you made it into cool
If central air conditioner turns on but is not blowing through the vents, check the filter. If it is dirty, change it. Change the thermostat into cool, this will defrost the air conditioner.
Check the temperature control cable
Low refrigerant charge? Temperature control cable not adjusted properly?
so its not blowing at all anymore, as in no air at all? if tahts the case then how do you know its still cold. if it isn't blowing as well you may just need to change out your filter, just like in a house all cars(most)have a air conditioner filter. if its not blowing anymore at all it sounds like your compressor or your whole dam motor went out, take it to shop.
If your air conditioner is set to cool and it is heating you have a broken thermostat.
cool air
An air conditionerÕs function is to take the hot air inside the enclosed space and release some of it outside while blowing a cool air in the room that is converted from the hot air. This process is being done repeatedly by heat exchangers found inside the air conditioner.
Sounds like the compressor coil is either blocked or plugged. It may also be the fan isn't blowing when the car is stopped also.
a air conditioner an cool you down
The most common cause of an air conditioner not blowing air is a plugged filter. Be sure your filter is clean.
