    Just some extra info on pulling the dash on a 2005-2006 Liberty...
    You won't be able to remove the dash until you remove two bolts UNDER where the two bolts that hold the steering shaft in place are located.... these two bolts go into the aluminum brace and are very hard to find.... They thread UP into the brace... after removing these bolts the dash can be moved forward.... Unlike the 2002 Liberties where there are only one pivot bolt are only one per side The 2005/2006 have one... Look for another bolt above the glove box latch and two bolts behind the radio/hvac panel...

    I thought this might help others with this job.... I got a 2006 where the previous owner(s) cut the bottom out of the hvac case to manually move the plastic doors inside... I'd rather spend the time and do it right... so the whole box had to be replaced...

    I just got mine in. Pulled the dash back like posted. I filled a Harbor Freight organizer with the fasteners and labeled everything. There are openings behind the passenger side air bag cartridge. Removing the cartridge gave me even easier access through those openings.

    Can you post a pick of the two bolts that thread up that you’re referring to. I have a 2006 that I’m stuck on with removing the dash on drivers side

    I found out I had a bad actuator after replacing the heater core...so I had to pull the dash twice.

    But that actuator cost 120 buck from the dealer$hip. I did not want to go used.
    Funny thing I went to the pull yourself junk yard. Every liberty ( about 8)had their dash cut with a sawsall just in the dash section to get to the blend actuator. Someone knows something about what makes money reselling parts on ebay.

    Has anyone attempted this on a 2011 Jeep Liberty? The symptoms sound exactly what mine is doing.

    I could be wrong but I thought the KK actuator was easier to access under the dash behind the glovebox. I didn't think it was buried behind the dash like the KJs.

    When you are installing the new motor, is it supposed to line up with the gear fitting in the hvac panel? Or do you have to open it up and rotate the gear to fit?

    Mine failed on the cold setting and I believe it is default for the system and the motor/actuator. I think every time you shut the engine off the blend doors move to cold and then reset to previous dial setting when you start up again. I guess I was lucky since it fit right on and lined up. I would think it would move without taking the thing apart but don't know for sure. I know you can use a 9V battery to run the motor and just reverse the polarity to move the opposite way so that may be easier to line it up (get it close) without taking the thing apart. There is a calibration process somewhere in the FSM but I never had to do that.

    You can just pop the clips on the sides of the actuator and turn the motor to fit where it needs on the hvac panel... Got mine working!

    Does the range work from full open to full closed or did you have to run a calibration?

    It seemed to work fine once I installed it. I did the calibration steps but I didn't notice it actually doing anything... My actuator was broken and would just spin nonstop in the direction you turned the dial, which caused the blend doors to get all jammed up. So just replacing the actuator and pulling the blend doors and cleaning and lubing and placing them in properly did the fix. Just sucks how much work just to get to those lol.
