175 amp APM fuse melting on 2013 Malibu

A dead short somewhere. That is a lot of amps.

and or the blower motor....

There looks like a lot of current going threw that fuse, what concerns me is the fuse did not blow. That usually indicates that it is too big of a fuse. I don't know what that circuit handles but like F.O.R. says, a short, somewhere. The other thing I can think of is if that connecting is not tight. Never the less that is a big fuse and is concern for starting a electrical fire. Need to have this looked at ASAP.

connecting=connection, sp.

If this vehicle has eAssist then take it immediately to the dealership. The 175 amp fuse is the correct size and the recall at the link may need to be done. Call your local Chevy dealership with your VIN number to be certain. See the recall .pdf file at the following link....http://www- odi.nhtsa.dot.gov/acms/cs/jaxrs/download/doc/UCM486217/RCR IT-13V173-5191.pdf

Also the fuse may be loose and need to be tightened.
