    I have an 05 silverado and ever since I got it a couple years ago the climate control has acted funny. First the fan stoped working on the 5 setting, then the blend door actuator went out and when i installed a new one it kept trying to open even though it was open. i tried a new control cluster and that did nothing and now the fan doesnt blow on 4. Someone please help!!!

    The problem with the fan speeds will be a blower motor resistor. From what I've heard, its not too expensive and it is fairly easy to replace. I can't really help you with the blend door problem though.

    You might need to reset the actuators... see this discussion/reply
