One or more heater & AC (HVAC) air delivery and/or temperature mode door actuator may fail. This can result in incorrect air delivery or temperature. If this occurs, fault code(s) stored in the HVAC control module should be available to assist with diagnoses.

    The problem is that the air only blos out the defrost and will not change over to any other outlets. I am having trouble finding the delivery door actuator for this, but have foound the temperature control one and it is working fine, so far. Any help on finding this thing would be appreciated

    Upon starting the truck, the mode door seems to cycle from floor to dash to defrost and stays at defrost regardless of switch position. Started IMMEDIATELY after replacing blower moron resistor. Have tried pulling the fuse for various lengths of time, turning off the ac when it gets to the dash position. All to no avail.

    Inlet air actuator has failed. Cold air on feet all the time. $1000 + to repair. May trade it off for this price.
