    Default No Cold or Hot Air through Vents

    Hello All,

    It's been a long time since I have posted to this website. I need assistance figuring out why my cold and hot air does not blow through the driver and passenger vents. I do feel the air backing up and leaking through the top of the dash board. Could the directional knob be bad?

    Thank You,
