Sony viem, že to bude asi aj u mňa problém s tými servomotorčekami pod palubovkou na strane vodiča, ale kým sa do toho pustím, chcem vylúčiť iné možné chyby, lebo s tým bude dosť roboty.
Napadla ma ešte jedna vec, prikladám z nejakého zahraničného fóra text v angličtine, kde bola robená podobná oprava.
Neveim po anglicky a teda som to pozeral len cez prekladač, čo ale nie je celkom dobré.
Ak to mal niekto porozoberané resp. vie o čo sa jedná, tak by to mohol skôr pochopiť a potom podľa toho napísať, čo ja asi problém.
Tu je ten text:
We had the same issue here on an E46 318I. When a/c on and face vents selected, warm air from centre vents only. Freezing cold on outer vents, when face, screen and feet selected, nice and cold on all face vents, cold on screen and warm on feet.
We removed dash, "modified" the heater box and shazam. Problem fixed, my customer too had replaced the heater control valve, control module(heater/ac controls) at anther indies' advise. It seems, reading all the posts regarding this issue. Alot of people have the problem but there is no definitive repair listed for it. Where the cable that runs from the centre vents ( the little dial with the blue and red dots on it) and connects to the inner flap, there is another flap that is inside the heater box, it swings by itself and is controlled by air speed and sort of runs off the flap the cable connects to.
It closes off the port from the heater core. If the heater valve is working correctly, the heater core should not be "hot hot". But it is still warm (compared to evaporator temp). This flap sticks open, allowing both cold and warm air to the vents. Because of the way the vents are set-up from the heater box to the dash vents, the rearward side of this outlet is the cold side and the rearward connecting vents are the side vents, so it makes out the sides are cold and centre warm. Its actually a mixture of air temps coming from heater box as little flap is not closing off heater core side....solution....free up flap then on the back of the main flap from the hot/cold dial, attach (glue) a small piece of plastic ( we used a 10mm plastic spacer). Then when the flap is moved, it "nudges" the swing flap earlier, gives it a bit more impetus to move and will not stick up again.
