That "old" topic open my eyes for some ideas of mine and thanks for those pictures and info. My "problem" if there is any, that somehow my Xantia Mk2 with A/C haven`t enough fan blow power or i think the case is that. All set positions Auto,1,2,3,Max - work. But.. well.. If i put the fan to max,close all ventilation exit and leave the flow-controller to window position.. still the flow is weak. I start to suspect the inside flap, or cabin filter...
With flow-controller switched to forward cabin ventilation position , i have one idea better flow pressure but again feel little weak. One other thing that i saw was that if the car engine goes overloaded , in example i drive on 3th but the rpm goes less than 2000 or even 1400 and try to keep up, the heating fan is on max but his rpm also goes down and rise again to max right after the engine goes up.
The weather is -16°C and is not such a time for doing repair or test outside, but i wish to get some tips in advance and to research the situation. Or maybe just i need to sit in another xantia and to see how actually is(was) before to make any tuning
Well the whole effort is because is so slow the defrost , or removing the moisture from my windshield and my memories from my ex X1 or ZX(non A/C) was for much faster and stronger effect.
