Sounds like a blend door problem. When you switch from heat to A/C can you hear a "thunk" under the dash on the passenger side?

I believe the blend door is working, air changes from vent to defrost or feet and temp of air changes from cold to warm settings. I there a way to check the door operation. The lines heading into the heater core are hot. When I change from defrost to vent I get a short blast of warm air and then it cools off rapidly it is not as cold as the outside air but alot cooler than the rear heat

Your recirc door may be sticking open or the blend door not closing all the way.

If the problem is the blend door or the recirc door how do I find out for sure and then repair the problem or is ther a quick fix until the temp rises, and I can spend more than 2 minutes out side without freezing off certain parts of the human body.

Thanks in advance
