Moin people, I have trouble again with my little darling. :/ The following behavior has been shown in recent weeks: Fans turned on level 4 > after 2 to 5 minutes the fuse burned through; Melting fuse replaced, a few weeks later identical error; repeated this error occurred, with ever shorter intervals between and melts on the fuse box; then Autohaus contacted > allegedly too high resistance of the fan as error ursa che called > Solution was use of maximum level 3; Hold in solution > last week then (of course with minus degrees and ice scraps) Total failure > weekend then sighting safety box > see picture 1; My question is now: I know, I have to replace the safety box and this will happen promptly. According to the described error description, what exactly do I have to replace, so that the contacts do not melt the plastic again? The fan (Fig. 2) ), the built-in fan resistance, or even both (or possibly other components)? Thank you in advance for your help!!!
