Probably the blend air door not working because of vacuum leak, bad vacuum check valve, or bad actuator.
Possibly the A/C air filter?
SOURCE: My air conditioner is not working on my 2002 BMW X-5. The air is cool it just won't blow out.
If there is air moving through the vents most likely the final stage transistor(blower resistor) has failed. It controls blower speed from a signal from the ihka (a/c control panel). the final stage receives the signal from the ihka of the drivers preference blower speed. the final stage pwm (pulse width modulates) the blower motor. which means it turns it off and on very quickly to speed up or slow down the blower motor speed. It isn't the easiest part to replace. Usually at a dealership i would expect to pay somewhere around $600 (including diagnosis)but don't hold me to it. bmw dealerships stand behind their repairs and usually include a warranty with the part of 2 years unlimited mileage.
SOURCE: 1992 Lexus SC300 Air Condtioner blowing cool/warm
the system is low on charge, it has a leak, repair the leak and recharge
SOURCE: 2002 Lincoln LS V6. AC blowing hot air but
its probably the compressor cutoff switch cutting your compressor off at the wrong time and causing your ac to blow hot. that switch is under your hood right on top of the engine easy to get to. I hope that helps you out!
SOURCE: heat blows out driver vent when ac on
this problem is caused by a defective air temperature control blend door actuator motor, it is about center of dadsh in air ducting, it moves the door that diverts air for cold from ac or hot from heater, you must remove the dash to repace it, about a 15 hour job fotr a home mechanic with a factory repair manual, nearly imposs without one.
SOURCE: AC blows hot air but AC compressor works
if the compressor works and your freon is charged it may be the blower flapper door....disconnect battery for 10 minutes and then re-connect to reset the electronics that control the flapper
