get my ac to blow out cold air. it doesnt even if its on cold on full blast when the engine is warm

try adjusting the room selector vent position to middle range rather than floor or demist. cool air is designed to operate at mid level positions and warm air upper and lower,
I'm am sure warm air will never hit you in the face unless you start sticking your head up on the dash shield.
1 make sure your ac is operating correct
2 adjust temp to comfort zone
3 adjust fan(s) speed to suit
4 select output direction
good luck i hope its only a directional problem i had some heater problems

bimmer3214,
Suggest you take it to a good shop for ACs for a leak test.
Could be anything from leaks in your expansion valve to a bad compressor.
Be sure, though, to take it to someone who knows BMWs. I first took mine to a Meineke and paid $75 for a guy to give me the wrong diagnosis. Then took it to a BMW specialist shop in NJ who told me the real deal.

Turned out the compressor/condensor was bad. Cost about $1000 to fix but now it blows artic cold.

Good luck!

is your auxilury fan working? do you need a refill the A/C?.. those two things are usually the main cause for AC not working

Darn Furios stole my post, but true cause those are the main things and don't cost the same as a compressor

I second what FUrious and BImmerN2B say. Also, check all the fuses related to teh A/C. I went without A/C for about two months just because I was lazy enough not to check under the hood. I did, and -- voilá! -- a fuses needed replacing.

Make sure you still have an ac belt. Its the lower two pullys. Mine snaped the other day.

I just refilled my AC the other day. Provided that your belts and compressor are in working order, the The DIY for recharging your system is good. http://www.bimmerwerkz.com/forum/mai...harge-665.html

One thing that the DIY does not mention, is that the target pressure is achieved when the compressor is running. When the compressor is off, the pressure will be much higher.
