Why aren't my middle air vents aren't blowing any air? Mode Door?

Asked by Dec 07, 2013 at 06:21 PM about the 2007 Pontiac G5

Question type: Maintenance & Repair

Ever since I got my car a year ago, the two air vents in the middle haven't been blowing
out any air. I can hear the air blowing, and both of the outer ones work. I still get both
air and heat blowing out of the outer two, and can feel slight warm/cool air in the
middle, but they don't blow.  Took it to a mechanic last week and they charged me $40
diganostic fee to say it's something with the "mode door" and it would cost $650 to
repair. Is there any cheaper way of fixing this problem, even if I have to do it on my

If it were the mode door you wouldn't have air coming from any of the dash board vents. Sounds like the duct that goes from the heater box to the center outlets has come loose and fallen down some. You'll have to get behind the dash to see what's going on. HTH. -Jim

JS0816 If the mode motor was replaced and it still inst working what could it be? I am being told something is seized before the mode motor and I don't know the name of it!

Have you checked the ducts, behind the dash, that go from the plenum to the dash? It still sounds like that's the problem. You're still getting air from the outboard vents on the dash but not the center vents on the dash, correct? -Jim
