Lever connecting ac/heat/vent/defrost came disconnected from control cable? How do you reconnect?

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.

Unfortunately, you can do it, but you will have to remove your entire dash in the process. It's not really difficult, just time consuming. You can remove the front dash cover by opening the doors and removing the covers on each side. They are just clips that hold them on. Take a flat screwdriver and carefully pry them off. You will then see screws on the side that you will need to unbolt, and I believe there are 2 more screws pointed upwards that you can get to if you open your glovebox. After those screws are removed, remove the defroster grill in the middle of your dash. There is just one screw to remove and it unclips. Now you can pry the entire top part of the dashboard off. There are more clips holding it on, so just be careful when you do it. After that, you will see a bunch of screws on the top side that you can unbolt and then you will be able to remove the front cover that sits behind your steering wheel. With these pieces out of the way, you can finally unbolt the front cover where your stereo is and get at whatever your trying to get at to fix your defroster/control knob.
I had to go through all this when I installed my aftermarket stereo.
Good Luck!
SOURCE: A/C heater vents will only blow out the defrost ducts.
Some times you can "reset" the computer for that by disconnecting the battery for 15 or 20 seconds then re-connecting it. If that doesn't work then the mode door motor assy might have stripped gears or broken gears. (they are plastic) If you are familiar with where the mode door motor assy is you can turn the knob to change the mode (i.e. defrost, panel, floor) and see if the motor is turning. If motor is turning and mode does not change then the plastic pieces have broke or stripped. Usually when there is a problem with the climate control system it will default to the defrost simply as a safety thing. So you will have defrost so you can see where you are going. Hope this helps you all out, good luck.

first check to see if you have power going to the actuators when you switch the switch to it location if no power replace controller if you have power and no movement from actuators replace actuator. if actuators move remove hvac box and check for broken blend doors.
