If the blower works well with direct feed get hold of a piggiback fuse, remove fuse F7 interior fusebox, put the piggiback instead and splice into the brown/red wire of C431, it appears in the second pic in post nr 3. If this way the blower will work you need another fusebox eventually if you are lucky it's a bad contact in the plug, C0584 - pin 2(brown/red wire)
