    Blazer A/C-Heater blend door actuator

    6 of 6 people found this helpful

    If you can't switch between hot or cold air on the Blazer HVAC system this is probably the problem. In other words it most likely blows hot air all the time. With the key on listen for clicking behind the glove box. If you hear the clicking a gear is broken in the actuator. Common problem.

    Follow these instructions to replace the actuator:

    1. Disconnect battery cable.
    2. Open glove compartment, and lift tab in upper left corner to allow the glovebox to swing down completely towards the passenger floorboard.
    3. Gently remove the line that enters the "Vac Unit", and then the "Vac Unit" itself by wiggling it upwards off its mount. Once removed gently swing it towards the drivers side and out of your way.
    4. You now have access to the Temp Actuator.
    5. Carefully remove the electrical connector that feeds the Actuator.
    6. Using a 1/4" drive wratchet, and 7/32" socket, remove the two (2) mounting screws. (HELPFUL HINT: For maximum ammount of clearance, Keep the wratchect handle facing the drivers side when putting it in place.)
    7. There is no screw on the back mounting post, just a pin that holds it steady.
    8. Once you've removed the screws you may need to gently pry the Actuator up off the blend door with a screwdriver.

    Installation is reverse of the Removal. The Blend Door and Actuator are both keyed, so there is only one way to put it in. Guide the Actuator onto the Door, then re-secure the mounting screws. Also make sure you don't apply power to the new unit until it is completely installed.

    Pros: Lifetime warranty

    Cons: None so far
