Assuming it doesn't need freon added it could be a bad high or low pressure switch. When the ac is on does the air conditioner pump clutch cycle on and off?

SOURCE: air conditioner blows hot air from dash

On most cars when you push a button or slide a lever to change your choice of location where you want the air to blow out louvers move inside the dash to redirect the air to your chosen location. When you switch from heat to AC other louvers move. These louvers are often powered by vacuum lines running from the engine. If one of these louvers is stuck or if you have a vacuum leak in one of the lines it may be causing your problem.

Probably, to be sure make sure the compressor is coming on. With the engine running turn on the ac and watch the rpms, they should drop for a second if the compressor is coming on. If so you just need to recharge, the refrigerant is R-134a, which you can get from your local parts store along with the kit needed to charge it. The kit will come with detailed instructions and is a pretty easy job.

2009 chevy AVEO 5 ac blows hot air

The guage needs to read between 35/40 psi.. If its much higher you may be overfull, this causes it to not cool.. Fix by letting some freon out, then top it back to needed pressure.. If pressure is correct, it would be a clog in the system.. Usually an orafice tube or accumulator..good luck!

Left Vents blow warm/hot air when calling for cold air

Usually a sign of a faulty blend door under the dash.
The blend doors direct air thru the ac and heater core along with the upper and lower vents.

2009 galant, added coolant.. still blowing hot air

Hi, there are several reasons your vehicle may be blowing hot air through the vents, such as a need to recharge refrigerant. There could also be a problem with the air conditioner's compressor. Vents will blow hot air if the compressor does not activate when the A/C is turned on. There may be an obstruction in the system, or the blend air door inside the HVAC unit may be stuck in the HEAT position so no air goes through the A/C evaporator.
