    Default 1997 Slverado 1500 Heater Control Issue

    The mode control knob on my silverado has no effect. The air seems to come out every where. When I was trouble shooting the actuator on the side of the heater box by the gas pedal, I noticed the little knob the actuator controls is broke off. Does any one have a tip or pointer on how to repair this? I look back through several pages on the forum and couldn't find anything. There seems to be several post on the blend door, but I couldn't find anything on this one. Thanks

    I seem to find a lot of info on the blend door itself, but I can't seem to find any info about the mode door, or whatever the correct name is.
