I had the same problem with mine. It was the thermostat, it was sticking and would not open until the engine got very warm and would force the thermostat to pop open, then the car would fill with warm air until the engine got back within operating temps or cooler, then it would stick shut again.

Why do engines need thermostats?
an engine runs best when at a certain temp, which varies according to the engine and how its used. a thermostat helps regulate this temp. too hot, and engines fail, or over heat, too cold, and engines can build up excessive carbon in the cylanders, as it is not hot enough to burn out; and also affect climate controls.(a/c heater) when an engine reaches a certain temp, the thermostat opens, allowing coolant to fully circulate in the engine, keeping it at a constant temp

Either the linkage from the temp control unit to the valve on the heater core (which is behind the radio and temp controls) or it is the heater core itself.
