MY car has A/C to keep in mind.When ive been using the climate system whether it be hot or cold,after a certain amount of time there will be some weird 'ticking' sounds coming out of the vents and or defrost,its not my fan motor under the glovebox but if i speed it up or slow it down the noises follow suit,and heres the funny part,if i switch from vent>defrost>floor,,nothing changes and the air flow will slow to nothing even though the fan is running full blast.any ideas folks?thanks in advance

sound like you have a vacume leak. i had a friend that had a lincoln that was doing the same thing. vacume line and servoes open and close all of the different doors. if you get a crack in a line or if it falls of it can make things act crazy. i would check out all the lines behind the controll pannel.
