These trucks have a problem where moisture builds up in the heater box then freezes. When this freezes and you change your heater settings it breaks the shaft for the blend door. If this is what happened you should be able to look under the dash above and to the right of the gas pedal and you will see two vaccuum accuators one of them you should be able to wiggle around the linkage if it is broke. To fix this you need to remove the entire dash to get the heater box out which involves discharging the AC and draining the coolant because the heater core and evaporator come out. Please rate.

I think u r right. this is a problem that most certainly requires a skilled technician to solve If u dont know of anyone who is good at this problem that leaves only the dealer and of course they are going to sockit to you. get an estimate.. it might be a good idea to check all your fuses first. then look under the hood for any loose vacum lines. dont forget your fuses under the hood usually in a plastic box.

you are sure the knob is not stripped right ....it all runs on vacuum look underneath and ensure they are all attached to the cluster on the knob as well check the vent itself and that the cable is not kinked preventing operation ..passengers side upper corner
