If the compressor is not turning on it could be as simple as low refrigerant level. If the compressor IS turning on, it might be a stuck heater core valve.
On the top of the ac compressor.
It may be the pressure releif on the bottom of the compressor. I do not have a turbo either and after I reved it some I got white smoke too. (from the oil in the ac system)

You take a piece of gum that you have chewed since you last changed the ac compressor. Then you take the piece of gum and stick it on the end of a straw and mold it until yu feel that it is secured tightly. then you blow into the other end of the straw and the piece of gum flies off, then change your damned ac compressor.
