Thanks, but i think there is the other problem. Everything is working (switches,LED panel - i did a self climate control). When i push AIR button, LED show more/little bars but fan stops all the time. Only when i set full speed of fan i can hear some click (like a relay) from voltage regulator(near fan, with 2 3-pin connectors) and fan starts working (full speed). If i push left AIR button and some bar on LED disappear fan stops.
I think a voltage regulator is bad, but i am not sure. I checked voltage on a smaller connector and there is voltage from 0,2V to aprox 6V depending on selected speed...Before i buy it i would like to know if someone else had the same problem.
