Question about 2006 Dodge Caravan
When you set control for floor it still blows out defroster and feet are cold
Most likely cause is the mode door actuator is not working. It is either an electronic actuator or a vacuum controlled actuator. It depends on the type of control unit you have. Most likely will be electronic on a 2006. Will most likely be mounted on the heater box under the dash. Not sure of the specific location, but on some other models, it is located on top of the unit and the whole dash has to be removed to replace.

Take a flashlight and look up under dash from center console area, across to passenger side, for wiring harness, and/or hoses(small rubber) , they should lead you to it. Haven't had my head under one of those recently, and having a problem tracking you down a diagram for some reason, but it has to be there.

you cant adjust it ,this requires the dealers computer to re set it,or a phyiscal control has packed up like a vacumn pipe has split where it pushes onto the valve that controls the flap in the heater unit.

Hope you have the same set up, sure you do. You may have either crossed your vaccum lines or when you were putting your heater/ac box back together or you may of pinched the vents somewhat closed. Cycle through the different zones to ensure the vents are moving as your are selecting (defrost, floor, ect...) If you think the vaccum lines are correct then you may have a reassembly issue with the Heater/ac box. I had the same problem with my 2000 Dodge Ram 4x4. Use the KISS rule "keep it simple stupid" start with the vaccum lines and all your wiring to the motors, make sure everything is plugged in. Hopefully you'll find it there before going back into the box again.

NO, PROBLEMS ARE NOT RELATED SEAT MODULE NEEDS TO BE PROGRAMMED AT CHEVY DEALER TO FIX ISSUE. IF YOU HAVE AN AUTOMATIC HVAC CONTROL UNIT WHEN YOU REPLACE THAT YOU WILL ALSO HAVE TO HAVE THAT REPROGRAMMED WITH THE LATEST UPDATES. BUT THERE ARE ALSO A LOT OF PROBLEMS WITH THE ACTUATORS THAT CONTROL THE MODE AND TEMP DOORS. THE ONLY POSSIBLE WAY TO DIAGNOSE THE PROBLEM CORRECTLY IS WITH A GM SCAN TOOL. GOOD LUCK

It sounds like you have a blend air door stuck. This is in the housing of the heater a/c blower unit under the passenger side of the dash. There is a motor on the top of the housing that could possibly be stuck or on working.
