Auxiliary Fans on 1993 W124 300D

[i-osprey]

Both my fans stopped working, again, today on a 107F day while doing three hours of highway driving.

It turns out that I melted another fuse.

I didn't break the filament, the plastic body melted.

Due to the melting, the fuse shifted in the box and caused it to lose contact.

Does this mean that one or both of my fans are going bad?

If so, can you buy individual fans or do you have to replace them both in one assembly?

I have searched the topic but nothing coherent enough for me to understand has materialized this way.

My A/C also seems to come on at the strangest times and when it does it doesn't cool very well.

For instance, I started the car, turned on the A/C, replaced the melted fuse(pictured below) and the fans started but the compressor did NOT.

I turn off the A/C, turn it back on and the compressor turns on but isn't really cooling that well.

I can't find anything but plastic bodied fuses anywhere either.

Where can I get some ceramic bodied fuses and would this solve my problem or just one symptom of it?
