Heater controls inop

(1991 Ford Ranger)
When I use my heater, it doesnt matter where I set them because the air blows from all locations, the defroster, the floor and the vent, what could the problem be.

The system that controls the airflow needs to be inspected, it can be something simple like a vacuum leak, broken control cable or something bigger like the control panel. Without inspecting it these are merely guesses. If you need to find a local shop, look here: http://repairpal.com/directory?distance=10&sort_by=relevance&address=42718&car_brand_names=Ford

I had the same thing happen to me on my 02 ranger. There are two vacume lines that go to a smog canister I guess that is what it is. Try checking those. One of the lines could have gotten a hole in it and if it did the door undrneith the glove box will not close because it is on a vacume line to open and shut when you change your settings on your ac. That is what it was on mine and I just put some tape around the hole and it was fixed. It is probably a grey line.
