…as already described above. the problem slowly goes to me on the eggs… that just at the beginning of the winter… I measured the relay. there then strange fluctuating values countered me (not fluctuating large). unfortunately can not say exactly how much it was (was long ago) hope also I did right, because I am unfortunately only skilled in mechanics. maybe still a small instruction to this?? I am unfortunately not an electro-crack… what could that be? or what could i ch still do? it only blows very very lukewarm… build year is ’92… please help me and you get n nice THANK YOU!
