My AC unit will only blow through the vents. When I change to the defroster or other, I can hear a noise but it still only blows through the front vents. Any ideas? I was thinking of the control knobs but now I think it may be something else.
x2 I think you have the dreaded blend door problem. Luckily mine was fixed under warranty. Now I need to replace the MTC, because there is too much of a temperature rise from full cool after just a couple of clicks from the full cool setting.
