My 325 E46 (2001) A/C blows cold for about thirty minutes,then turns to hot on it's own. Can this be an evaporater problem? Any help is appreciated.

Does it have auto climate controll? If so, I'd say you have a climate control computer or sensor issue. You should have the dealership look to see if there is a TSB for this (technical service bulletin) or even a recall. If nothing else they can tell you if the symptoms are indicative of a common problem that they see.

Your car might also have reached the temperature you told it to reach in the automatic climate control system?
