Hello @ all, I have a strong problem since the beginning of the year that as soon as I turn on the climate it starts to fiep cruelly. Sounds really crazy. Meanwhile it makes this sound even when the climate is off. Think this comes from the direction of blower? Perhaps. Relay defective? The sound is apparently also speed dependent because when I step the clutch and it is going away at 800Upm. cupper I again is back after half a minute. Hl this is also gone and comes back when the speed falls. Furthermore, there is another thing that slowly disturbs me. When the climate is on and I turn on the light, the blower switches off completely. climate cannot be switched on/off. Circulation air no reaction. Light in the instrument board becomes darker. Only when I wait for the ventilation position to 0 place and a few seconds the ventilation works again. Platin defective? Relay defective? Thanks everything that can help me. .
