OK, so you have the electrical type that uses a potentiometer behind the panel connected to the knob to control a motor in the blend door actuator.
Yes, the blend doors do break and cause heat control problems in Rangers. But that is up on top of the plenum, not down at the knob.
So, now we need to go back to your original problem. Is the knob loose/broken at the dash control or are you having a problem controlling the discharge temperature? I can't really tell from the original post.
The knob should turn left and right without too much resistance but it should also hit positive stops in both directions.
