What have you done to the AC so far??Gotta help us so we can help you.
What setting do yu have the AC on?? "EC" setting sucks, its usually too warm, lower the temp using the adjuster on the climate control unit. If all else fails, try:
New AC Dryer??
Freon Recharge(R12, if available)??
Try those first
