Question Question about fuse melting in fuse block

Folks, on the circuit which resides the AC in a 1983 300d (123), I believe it is the no. 8 fuse that didn't blow, but caused the area around the contacs to melt. Yesterday while driving in the morning, I smelled a burnt plastic smell, and as I had replaced this fuse 3 times in the last two weeks, I took the top off of the fuse block and found that the fuse was intact but had melted the area around the contact. I immediately replaced the fuse, but was wondering if both the AC blower motor as well as the AC compressor were protected by this fuse. I'm thinking that perhaps the AC blower motor is drawing too much current, and was wondering if you all had any suggestions I thought about perhaps removing the blower motor, and putting a few drops of transmission fluid on the bearings to see if, by lubricating them, I could perhaps lessen some of the amp draw.
Any suggestions and advice are greatly appreciated, thanks so much in advance!

Common problem and many just add an aux fuse holder and rewire.

Question Question about fuse melting in fuse block

Can anyone who has spliced into the fuseblock to install an external fuse holder describe precisely how this is done? Is there enough space under the fuse block to get ahold of the two wires that attach to the #8 fuse to solder in new wires to the external fuse holder?
Thanks so much in advance for your help!
