My #8 fuse gets very hot and has melted the fuse holder a little. I have replaced the blower motor and it is still doing the same thing. The blower will not blow the fuse on low but I can't run blower on high for very long tops 5 minutes maybe. After running the old or new blower on high for a few minutes the air smells bad not the common hot smell but kinda fishy . I had the a/c redone over the summer I mean the whole thing now #8 is blowing. I know this has been covered a few times but not with the smell . kinda new too these Mercedes any ideas would be greatly appreciate. Thanks
