s430 Fuse Box question
 

When my A/C is at full, the motor will shut off. I figured it was just a fuse and it was just that. It is the 30 amp fuse located at the fuse box under the passenger side window. The color of the fuse box where the fuse inserts to is brown. What I noticed is the fuse melts and the area where you insert the fuse if broken, why I think the fuse melts. My question is as follows. Can that area simply be replaced, by popping it out, or do I have to purchase the entire fuse component. Also, would it be easy for me to do? If so, can it be purchased from the parts shop. Any input would be greatly appreciated.

The 2000-2001 S-class W220 chassis are having many problems with this circuit. Possibly a recall according to inside info from dealers.
