NG ignition off, ventilation & lighting goes anyway !

Hello guys, I’ve had a problem since today. At my convertible NG last week the battery was empty. Then I installed the battery out of the Coupe and left it overnight. This morning the battery was empty again. So again another battery in and through. Did not measure any waste of the current with the pulled fuses, however, the alternator does definitely charge. Then I noticed that despite the switched off ignition and pulled key the Windscreen wiper, which can turn on blower, furthermore, the lighting on the doors for the el. FH. permanently lights up. Since I don’t know about electrics so great, and I did not find the same case here I hope that one of you can help me. Thank you already Gruss coupeka
