Overloading the circuit, short in the wiring, or incorrect fuse installed which is too small for the circuit. Always use the correct size fuse.

I'm not sure I understand your question. I can't tell if you have one or two different fuses "blowing." The only thing which causes fuses to "blow" is a short circuit condition in the circuit which the fuse protects.
