You probably have an electronic air cleaner. That's a GOOD thing. The electronic air cleaners do a remarkable job of removing dust and pollen from the air. The filter needs to be cleaned occasionally but you should refer to the owners manual to make certain that you don't damage it. They are expensive to replace.

Why is there is a loud clicking sound when the AC is turned on in my 2005 Chevy Tahoe?

I'm having the same problem with my 2003 Tahoe. At first it was just the clicking and within a month the dash vents stopped working. Now it only blows through the defrost vents. From what I have read and heard from a couple of mechanics it is a bad a/c mode door actuator. Dealer charges somewhere between $700 and $1,000. I've read that to do it yourself it requires a special tool.

Why is a ticking noise coming from the ac vent behind the dash. when you turn on the defrost it goes away?

i have recently encountered this on my 2002 GMC Envoy. After removing many of the underdash parts, ie, shroud under the dashboard, and some of the plastic vent ducts i identified the source of the sound. There are three separate actuator motors that help to control which vents the air comes out of, ie defroster, dashboard vents, or foot vents or some combination therof. One of the actuator motors is causing the clicking sound. Unfortuantely, you can only change the lower actuator motor from the bottom, the other two SEEM to have to be accessed by removing the dashboard and/or center control panel. I am currently researching this to perform the repair myself, because a trip to the dealer is certainly not going to be inexpensive.

Well first of all.. You want heat in your house when it's cold, RIGHT? So you turn on the heater with the knob.. and the heat comes out of the vents. No vents = explosion. And basically.. no vents as I said.. explosion, because the gas has nowhere to go so the pressure will build up and BOOM.. flames.

There is a door that diverts the air from the floor to the roof vents. It is controlled with a plastic gear and arm. The gear has stripped out and needs replaced. It's a $35 part but it takes a few hours of labor to replace it because you have to remove so much of the interior to get to it.
