Hi to everyone. I have a problem that's a nuisance.(190 Cosworth) My heater blower is not working., or at least no power getting to it. The blower is working when connected to battery. I can't find the fuse for it. 20 Fuses in the fusebox all accounted for. However on the glass display cover on fusebox it also lists an outside fusebox. Is there another one? Can't find one for the life of me. Any suggestions much appreciated. Also anything else I should be checking. Thanks, Martin.
