Blower Motor Fuse ?Melted?

Hi Everyone,

Having a problem with my 1986 300E blower motor. The fuse is getting very hot and melting the plastic, but not blowing the fuse. The fan stops when the melted plastic makes the fuse no longer contact the fuseblock. I can't really think what would cause this except excessive current draw.. maybe a blower motor resistor or regulater? Anyone heard of this before in these cars? I have a mutimeter, where should I test for this and what should I inspect? I appreciate everyones input


Thanks,
