I replaced a blend door on my 2000 Gmc Sierra. The one that controls the hot/cold blend door. When I replaced it, it will not bolt on unless I turn the blend door a few clicks to the left towards hot. Now the a/c blows warm all the time. Is there a recalibration for this older model? It is not dual climate controls and not auto controls. |

What is the part number of the actuator you installed? You mentioned that you turned the door a few clicks. Does something click when you rotate the door shaft by hand or were you turning something in the actuator? |

The part number is 604-101 . No I have to turn the knob on the controller a few clicks not the blend door itself. |

Okay, the ACDelco part number is 15-72507. When you go to Dorman’s site and cross reference that part number you come up with two Dorman numbers, 604-100 and 604-101. I find that strange and would recommend installing an ACDelco part. |

I spent the money and bought an ACDelco actuator and installed it. Is there a sequence to recalibrate the actuators? |

GM does not list one for a system with manual controls. |
