You have dual zones that are controlled by temperature actuators the passenger side has lost its memory or has gone bad you can put it in self programming by disconnecting the battery for ten minutes then hook it back up start the truck turn the temperature control on but do not touch any other controls let it go thru the self programming for about 6 to 7 minutes then select your temperature you want if it still does not work properly you may have a bad actuator or a bad connection at the actuator

There is a flap that directs the air. the flap is controlled by a vacuum actuator. This is located inside the venting. The actuator is connected to little vacuum hoses that attach to the temperature control switch. Either the flap is stuck, or the actuator has gone bad.

If you car is coming to temp but you get nothing from the heater the first place to look is the coolant valve for the heater core. It is sometimes called a mixing control. See if the control is jammed or your control cable is frozen or disconnected from this valve.
The valve should be somewhere near the cooling lines leading into the heater core. I am sorry, but they may be under the dashboard as well.
Good luck and be careful.

I just had the same prob. Your air blend door actuator has probably gone bad. Take off the glove box and look 4 a little black plastic box(oddly shaped)with white plastic arms connected to it. Turn the knob from heat to cold. If those arms dont move thats your problem. Or when u turn the knob, u hear a clickig noise inside the dash, thats also the air door actuator.
