a/c help

when i try to turn on the ac on my 93 euro. hot air comes out. the sad this is the a/c air is hotter than when i turn on the actual heat. can anyone think of how i can fix this, and maybe its relative cost?

if your engine is cold and you start up the engine, turn on the AC, is the air hot or the same as the temperatureoutside? If the air is the same as outside, then maybe your Warm/Cool air vent door is stuck.... when the engine warms up if it starts blowing hotter air out... that will help confirm that it's your temperature vent control that is bad.
