The vents/console noise has never been there in the past when using defrost. It also will make the noise when I go from the lower/upper setting to the upper setting as well.bbomar said:Well, the vent noise is from your vents switching off from outside air when defrost is on, and then redirecting the air flow.
As for the clicking, could be alot of things.
Do you have the chrome wheels>
You could fix it yourself but you will need A LOT of patience. First you will need to unbolt the BCM (right above the gas pedal) then you will need a 5.5 mm 1/4" socket and ratchet for the screws that hold the mode door cam on. There are 3 screws. 1 is the top right screw that holds the mode door actuator to the cam. There isn't much room to work and you have to do it on your back while laying on the floor boards. Once you get it out and start putting the new one in you need to make sure the mode door arms go into the slots of the cam. If you don't get these arms in the right position then the doors won't work properly when you go to change modes from defrost to vent etc. It can be a pain in the @ss!
