    There are plastic gears which turn to control the vents. Likely one has broken (the gear tooth or teeth) and makes a clicking noise until it finally engages.

    That was just a guess as my 2008 Impala LTZ has them - (3) different gears to be exact. I know my local parts store carried them. You need to determine which one is making noise though if that's the issue. Mine were located behind the glove box. I have never had this issue in my 02 Camaro SS so I am not certain off-hand where they are located in it, or how to access them. You might try calling your local parts supplier to see if they can assist if you have no luck searching online.

    Mine has been doing this for 3 years now. I thought it was just a noisy AC lol. I would like to fix it!
