AC will only blow hot/warm air.

Hi,

Im at Phoenix Arizona right now with my car (2005 production year 325i) Its been about 95-100 degrees during daytime and my AC will not work! I got in the car at around 1pm yesterday and I set the AC to MAX COLD and for about 40 mins of highway driving it still blow out warm air... I took the car to the dealer last summer for the same issue and they told me theres nothing wrong with it. It only does this when its really hot and sunny... All other times it works fine...
What might be causing it?? I really need AC here in Phoenix....
Thanks for helping!

Compressor might be broken. Most autopart stores have "freon" like products that you can spray into the A/C system. Ask your local autoparts store what they have to help.

^ +1, if compressor still works then you need to recharge with new freon

The term is "refrigerant". "Freon" is a DuPont trademark for their line of refrigerants, but is often used generically to refer to refrigerants. You should seek professional service. If you just go dumping refrigerant in without knowing what's wrong, it could cause bigger problems. Most indy shops can diagnose the problem quickly. If your dealer told you nothing is wrong, take it to a couple of other shops and get second (and third) opinions.
