    Default Heater Problems

    Hi Everyone!
    I am having issues with my heater in my 09 silverado.. My truck is loaded and has dual climate control. The problem is one side of my truck is blowing cold air while the other is blowing warm air. I would prefer it to be blowing warm air as it is -20 up here. It even blows cold air when the passenger heater is off. Has anyone had this problem?

    A very, very, very, very, common problem. try a search using "actuator".

    Sometimes, the actuator can be reset with a battery disconnect/reconnect.
