Air Conditioning problem
2000 Saturn Station Wagon 4 cyl Two Wheel Drive Automatic

When turning on ac, sometimes it will blows cold and sometimes not. When turning on just the vent, sometimes it blows and sometimes not. The button that will circulate the air inside the car doesn't work. If I have the ac on high and it's not working, sometimes while driving, it will turn on, also if it is working and while driving it will stop blowing. I have been told by a ac mech. that it could be the high pressure switch. Do you have a idea what this problem might be?

Could be freezing up due to air and moisture forming ice and blocking off the orifice tube try having it vacuumed out

This happens when I get in it in the morning. It hasn't ran all night.
