I was fiddling around and noticed this fuse and went to check and make sure it was good and when i pulled it out it just fell apart, any idea on what this is for? its a number 30

my stereo perhaps? i didnt hook it up originally so im not sure.

Thanks!!!!

 

is this on that blazer in your profile pic? and what year is it?? it looks after market could be for a radio or another accessory can you see where the wires lead to

 

its the 04 blazer, im thinking its the amp fuse but im not 100% sure.

guess i will find out when i leave from work in 1 minute lol

 

could be kinda small for an amp but u never know ...

 

mine looks exactly like that too. in my case, its for my security/remote start system. do you have an aftermarket alarm, remote start, keyless entry or all?

 

alarm yes, but its the factory alarm. i drove home fine, didnt notice anything not working. i think its the amp fuse. i dont have it installed right now so i couldnt tell if it was off or not.

 

I have never seen an amp fuse like that before, besides the ones that are ACTUALLY part of the amp.

 

+1 on that

 

It ain't factory, guaranteed. Could be for a remote start, stereo, fog lamps, who knows. Follow the wire and see what it goes to.
