    05 escalade pass side no heat

    So I have an 05 escalade and pass side has no heat, found the blend door actuator and it wasn't doing anything I moved it manually and it goes hot and cold on the
    Middle face vent beside the stereo nothing on the pass side vents or defrost or feet. Located the actuator on the upper side of the heater box didn't see it move at all
    Either no matter what I did on the controller. My question is what controls passenger heat for defrost and face vents? I know there is 3 actuators on the pass side heat box one on bottom on on pass side and one on top. How do I get to the one on top or the side cause it has to be one of those two. Any help I appreciated!

    I think it is the Stepper Motor?

    Have you tried pulling the hvac fuse

    Pull the hvac fuse for two minutes
    Put it back in and turn the key to run(engine NOT running) for two minutes
    Turn the key off then start the truck it should force the system to calibrate itself

    If not then it would be best to get the system checked for codes

    My rear hvac system threw a over travel code and I had to replace the brain box as I got nothing but ice cold air in the winter(women hate cold air in the winter) also had to replace the temp door actuator as it failed at the same time(long and expensive story)

    Re: 05 escalade pass side no heat

    The dealer ran it with no codes preset they said and they said that the could "see" all the actuators if that makes sense.. I'll try the have fuses tmrw and see if that works. Does anyone know which actuator controls the heat for the pass vents and defrost? Also if it's the top actuator on the heater box how do you get it
    Out? Again all help is appreciated guys!

    Going by the manual cadillacman sent me looks like my control module is bad. Is this common in these cars? Also does anyone in my area (Portland Oregon) have one that I can try to make sure It works?

    ----------

    Also how do you reset the actuators? Thanks again

    ----------

    Also how do you reset the actuators for when I replace the control module

    The control module can be bought at a salvage yard

    Resetting the system is done when power is applied and the key is on for 2mins
