Here are the recent answer to this question.
We bought my daughter a 1998 ford ranger. The air conditioner would not hold charge. Then the heater would blow luke warm air even after running for a long while. Since I really dont know if yours is doing this or just not working all together. It's really hard to say but, here is what we did to fix hers with her problem. It's called air door actuator.
If you are close to a napa store the part number is 655-1551 (this was for a 1998), but still might be the same. And here was the kicker; t was located inside of the glove box. Well the glove box was taken out it was in behind it. Hope this helps or it may help someone....and my husband says I shouldnt keep all those boxes of used parts...lol.

Sorry I can't help, all I can do is sympathize. I have a 2004 Ford Explorer and the heater quit working. 3 repair shops all said it will cost $1,000 to fix it because it is so inaccessible. Something about a 'blend door'. I am so mad at Ford I will never buy another one. In the meantime I can see my icy breath in the car on a cold Oregon morning.
