Warm it up & feel the heater hoses. If they are hot it's a problem with the blend door.

If they are not hot is there a valve in one of the hoses? Is it working?

Check your blend door..take your glove box down by simply pushing in the sides with your fingers. Depending on year of ranger you will see a black box, reach your hand in and towards the middle of the truck and you should feel this door..you can move it by hand. Also note some models have an actuator behind the glove box that move that door. I would check that first. Good luck. I only know because my actuator went bad and i did all of that as well. Good luck!
