My 2004 Buick Rendezvous has very little air flowing from the vents even though you can hear the fan blower quite easily at all speeds, low to high This is the same for air coming from all vents, floor and defrost mode, all with very little air. I have replaced the cabin filters in the glove box to no avail. Sounds good, but don't know where all the air is going. Should also mention that vehicle has automatic climate control. Appreciate any help.

Does it seem like what little air flow you have is coming out everywhere? Ie, floor, defrost, dash vents? Please advise.

Hi, Yes, there is a air blowing lightly through all the vents. Not a stronger amount out of any praticular vent. However, when I change from say floor to defrost, you can hear a change in the air flow? Appreciate any advice.

OK, there are 2 servo operated dampers on the heater box. You'll need to varify if both are working when you change air modes. Also, there is an actuator "rod" to change air flow. My description of this is not clear but you need to be sure this is connected.

Thanks for the info, do you have any idea how much it would be for dealer to look at and possibly repair? I'm not overly mechanically inclined. Is this something an average garage could fix?
