sounds like a heater core issue. are you losing coolant? is the car overheating? is water leaking out of the firewall drain hole on the passenger side behind the AC evaporator? do you have a puddle of coolant soaked into your rug on the passenger side? Your problem sounds like a bad heater core to me. don't worry, the good news is you only have to remove the console and the dash(if your really good i think you can get the dash out without removing the console) my last core only cost 25 bucks from A&A. good luck. and make sure you check the heater core hoses and replace those along with the clamps.
