Sounds like a problem with the front blower motor. there is a blower motor resistor for the front blower motor that controls the speed of the blower and tends to go bad or fry out the blower motor. thats the most likely scenerio since you stated the control head was lighting up and responded to button changes.

the problem is in the rear expansion valve. this valve is located at the rear evaporator core. i am assuming the freon level has been checked and is ok. this is a common problem with these vehicles. hope this helps!!

Is the blower running? Is coolant hot in the heater core when you set controls to hot? Do you have a picture of which setup you have?
