I'd like to know if anyone has experienced similar problems as I am about to describe with my C5. Hopefully you can give me a solution or at least give me enough knowledge that I can talk from an informed point of view when I go to the dealer with this one. I get no HVAC codes. Display always display what I select, but with no results.
Heater and A/C ducts all seem to disperse a little bit of air.. all of them.. all at once, regardless of the settings. For example, I can choose "floor" but it makes no difference.. all vents (floor, dash and defrost) all disperse a little bit of air. Makes no difference what mode I am in.. be it ventialtion, heat or A/C. Seems like the deflector doors in the vents are not functioning or ???
