your air mix valve could be stuck on open. check that. Also I had the sam problem and it was due to the inner dash having broken hoses (the ones that lead out of the heater core box over time they just fall apart).

Sorry i meant your "blend door" and it is in your dash. As I can remember I think you can reach it from taking out the fan under the hood. it should be attached to the lever on your dash that reads "vent heat."
