Look near or behind the alternator. The valve that controls flow of coolant to the heater core on my 1987 Aerostar is located on the left wall of the engine compartment. I imagine the 1991 is similar. Trace the heater hoses from the engine/water pump and you will find it.
Make sure your heater control knob is not cracked, or it will just be slipping on the shaft. Also inspect the attachment where the control cable attaches to heater control valve (underhood). You can adjust the tension of the cable by pressing on the tin part that holds the cable sleeve in position. IF you have done the above, there are a couple of other possible faults: 1) Faulty thermostat (stuck open) 2) low coolant levels or other cooling system problem
can happen when vacuum line is disconnected . look under hood to right of heater hoses. one vacuum line goes to heater valve (gate)on heater hose ,the other should go past this to a small sized metal object the size of a small lemon. if this is disconnected only defrost will work. I HOPE YOUR 91 IS SIMILAR TO MY 93.
If the blower is good then the problem is coolant. Something is stopping the warm coolant from the engine from reaching the heater core inside the car. This might be thermostat, heater control valve, blocked heater hose or a blocked heater core. I would suggest letting the car warm up and checking the heater hoses (2) by hand to see where the hot water stops. If there is no hot water at all it is probably a thermostat problem.
