so suddenly at the start of summer when I try to change the ventilation mode in the climate control panel in order to have air blown at my face by the AC vents ;it does not show the mode and it does not matter how many times i try to change it, it does not show the ventilation mode its working on (dimmed nothing shown).
the problem is that I think that the vents are shut and it does not matter how hard the fan runs; still no air comes of the vents (central & side) noting that i changed the interior fan about a month ago because the old one was noisy.
the other functions of the AC control panel are OK ( such as fan speed selection, temperature selection, operation of compressor..etc).
Is this a bad AC control panel that needs replacement ?? or what I can do ??
