probably a stuck open heater valve try smacking it with a hammers handle, it's the bit with the two quarter sized round bits on top next to the fusebox, theres a valve for the left and right sides of the car, wack the right one a couple times and see if it pops closed and the air cools down. if this works you will eventially need a new valve assembly as it will stick more and more over time
