    a/c blower on the blink

    03 EXT

    first, i had the heated drivers side/normal pass side-havent fixed it yet as its no big deal, id turn it on and off a couple/few times and it
    would go back to normal

    tonight, after work, fan was on high, tried to turn fan down, wouldnt,tried numerous times
    hit power button, only switched air flow to floor
    turned off key, fan stayed on
    pulled both harnesses out of climate control in dash, fan still wouldnt stop
    had to pull relay under hood to get fan to stop
    air was still cool
    any suggestions or is it off to the tech to pull codes ?
    thanks in advance

    ----------

    blower motor resistor OR blower motor module ?

    Its the blower control module
    Its under the dash next to the blower behind the hush/kick panel
    Remove three screws(1 is going to be a pita to get to)
    Remove the hush/kick panel
    The module is right next to the blower

    FYI when the system is shut off the floor position is the default rest position for the mode door

    Re: a/c blower on the blink

    i called caddy today to get price
    they told me there are only 3 components to the system, blower fan, dash control and resistor under glove
    i was under the impression there was a resistor AND a control module under glove
    are they using another name ?
    can someone clarify for me please ?

    They may be thinking of some of the older systems(which does use the resistor pack)
    The controls you use to adjust the system is the control module the works the whole hvac unit
    The blower module is what the control module uses to control the blower motor

    The manual hvac units use a resisitor pack for the blower the auto climate system uses a blower module

    I hope that was helpful
