A/C functioning properly but blows hot air

Check this information when car airconditioning blows hot air http://www.cartechhome.com/2008/07/your-car-air-conditioning-system-is.html

You need to check the low and high side pressures,of the system.If the low side is above 30 psi and the high side is somewhat lower than 150 at like 1400 rpm it may have an expansion valve bad!There may be a faulty or stuck water valve that closes the water from intering the heater core,which,is not used with a/c on!Is the cooling fan for the condenser working.If not this will cause high head pressure and no or little cooling

hey you need to see if you blend doors are opening and closing properly, the hot side may be stuck open and the cold side stuck closed, the spellig maybe wrong but check on you actuator its a little gear thing that opens and closes the doors for your vents
