The following doesn’t work: Electric window lifter + central locking / radio + blower + flasher + tank display + and probably a lot more, which I can’t just check everything. I just bought a car ( Alfa 156 – EZ 2000 . 1.8 liters – 106 KW) and is not standing with me because of other problem. There should be a control unit for these things (and possibly other failures) that should be on the rear wall in the trunk under the panel. Who knows about it – about costs / other problems etc. I am grateful for every tip, because I am dependent on cheap (selbermachen) – possibility because of lack of money.
