W204 vent mode selection not working
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 ??
