A/C Vacuum Diagram
SOURCE: No Heat..Heater Core Is Heating..Vacuum Lines?
I have a '96 Eddie Bauer Limited and it has the same problem. They told me that there is a small butterfly valvu located in the vac lines to select between hot or cold air. There is a tension spring connected to the valve, to an acutator, and to your ac contorl system. The spring on mine broke, so the valve opens and closes due to suction only. It is supposed to be about a $700.00 fix (due to the valves location by the firewall) but I have found a way around that. Try to aggressively apply the brakes making the vehicle slow rapidly, and at the same time turning on the blower fans with full bast heat selected. If this does not work, try doing the previous while going around a right hand corner. The corner will help the momentum of the valve turn in the right direction. Remember you have to switch the fan on full blast when you try either. If it works you should hear a thud as the valve flips shut and the heat should start coming out of the vents.
Good luck

Check the white vacuum hose going to your recirculation vacuum motor under the hood to the right side of the fire wall. It runs inside a wiring harness. The hose will get brittle and break apart. Start there it is the most common vacuum leak on a ford truck.I hope this helps.
