    Are you referring to refrigerant in the system? If so, if i were low wouldn't the compressor not come on? Just asking.

Check the aircon gas is filled up, this is something that needs to be filled up once every 2-3years especially if used often. There should be a metal pipe running to the aircon radiator tank with a small glass window somewhere. This should be green from the gas inside, if it isn't it's empty. Take it to a workshop, it shouldn't be more than a few dollars for a refill. Hope that helps!

03 grand am ac wont blow cold air


Two things are very likely to be your problem. Freon or compressor. Turn on the ac on cold and see if the compressor is engaging, if it is and stops and goes or if it doesn't. try to check the compression on the low side of your ac, the smallest plug where you service the ac. Or take it to an ac professional to get it refilled or checked. Remember, just because its blowing air, it doesn't mean its working. There are fans inside the car that push the cold air inside your vehicle and most of the time these will work, but that's not the only part required to blow cold air inside your car, the compressor is what makes the air cold.

Low freon will cause the compressor to short cycle, when the compressor runs the pressure in the low line is pulled down and the low pressure switch turns it off. Not running the pressure builds up and turns it back on. In the old days there was no low pressure switch, with no freon to carry the oil the compressor was destroyed.

My air conditioner is blowing warm air on the driver side and cold on the passenger side


see this steps and think with clearly and logically NOT feared. God bless you
checkmark.gif Start with the compressor. Does it engage when you turn on the A/C?
If so, the compressor is working and the A/C system probably contains enough refrigerant to make cold air, so the problem is inside the HVAC unit. Replace the motor that controls the blend air door (this is a difficult job and best left to a professional since it involves tearing apart the HVAC unit -- about an 8 to 10 hour job!).
If the compressor does not engage when you turn on the A/C, see if it will run by jumping the compressor clutch wire directly to the battery (use a fused jumper wire). If the compressor works when you jump it, and the A/C blows cold air, the system contains refrigerant and the fault is likely a bad A/C compressor clutch relay or a bad clutch cycling switch or pressure switch.
If the compressor does not engage when you jump it, the problem is a bad compressor clutch.
If the clutch engages but the compressor does not turn (the belt will start to slip and squeal), the compressor is locked up and you need a new compressor.
If the compressor clutch engages and turns the compressor, but the A/C still does not blow cold air, the system is probably low on refrigerant and needs to be recharged.

Air conditioning blows hot and cold air


You will need to know if the compressor is working when it blows hot air to proceed. It could be an electrical problem, a blend door problem, or the a/c clutch on the compressor.

Hi there. When a compressor is replaced, two things are in fact being replaced - both the compressor and the refrigerant (Freon) and if the problem is resolved as a result which of those two replaced elements caused the original problem? Well you will never know and so before the compressor is replaced you need to have you’re A/C system recharged – it’s by far the most cost effective initial thing to do. In general A/C systems loose at least 10% of their effectiveness each year through loss of refrigerant and so given the age of your car; it’s the first thing to focus on. A professional A/C centre will also be able to tell you whether your compressor is working properly after having a refrigerant recharge by the monitoring the operating pressures in the A/C system.

Ac blows hot air ac compressor is ice cold but the vents blow hot air when enige is hot. bloows cold air when engine is cold


check your air diverter doors, sounds like the door for heat is open, when a/c is selected the doors should move and close the heater off. the heater will over power the a/c. the door controller is located on the environmental station under the dash neat to the floor. the control is electronic and probably not functioning
