Question about 2003 Ford Explorer Sport
The problem you have is that the temperature control door is not actuating. This is the air blend door in the box under the dash that houses the heater core and the A/C coil. This door allows the different air temps to come through depending on your settings. The temp door is either stuck or the vacuum pod is bad. Have it replaced and that should get you back in business. Good luck.

You need part GM Part number 89018675 or ACDelco 15-73596. The Mode Selector Actuator. What happens is the part is a CHEAP part POORLY designed and when it goes to turn the flaps inside the HVAC unit its the plastic gear slips instead of turning the flap!!!
Just to forward you you might want a deal to install this art for you unless your good at fixing your own vehicle, because you need SMALL sockets and a lot of patience to get this part in!!!
The part is ALMOST directly above the steering shaft for your steering wheel, so theres a lot you got to remove before you will even see them!!!
I only recommend you to have a dealer put this part in for you, unless you have your own service manual!!
Because there is 5 of these darn things and if you pick the wrong one you will have to do it all over again!!!
3 on the Drivers side and 2 on the Passengers side!!
But replacing this part SHOULD solve all your problems!! AS it did for me and i was having the same issues as you have described!!

You have a vacuum leak.Defrost is the default postion(no vacuum).
See if you can locate the small black vacuum line that goes inside the vehicle on the passenger side near the heater core. The trace it back,should see it going to a canister then to the intake manifold.Make sure it is not disconnected or broken somewhere.
