Melting fuses question

[mikesz]

Anyone have an idea why my car is melting fuses? About a month ago the heater blower fuse melted. I mean it was a glob of melted plastic and one of the blades and broken off and was still in the fuse block. I had to carefully fish it out and replaced the fuse with a new one. 2 weeks ago same thing happened to the fuel pump fuse only this time it melted onto the fuse block. I had the car towed to the dealer and waiting for a new fuse block from Germany. I have never experienced anything like this with any car I ever owned. Just wondering what would cause this to happen.
