The air conditioning does not work. Despite recalibration, error code 0, the system does not cool. ACC shows the set temperature, (r/l 21 degrees), also wants to cool accordingly, i.e. blows and blows, but no cool air. Was about 8 days ago at Hirsch, who also replaced the pulley for the poly-V belt, because of strange noises, before they installed new brake discs and pads for my deer. Since the weather did not require air conditioning cooling, it could be that from this time the climate compressor, because maybe a power cable slipped off or so, does not get any more power and therefore can not cool? I mean, that the compressor is usually more clearly heard than at present! The fuse no. 20, has been checked. Is there any more special fuse for the compressor or is it possible that the compressor suddenly and completely fails? Greetings Wolf, to all and especially to all the answerers, from the Palatinate!
