I'm new here,just wanted to see what was making my Horn fuse blow?I just purchased a 2000 blazer 4.3L V6 any ideas folks?

 

It's possible your horn has died. The stock horn in my Jeep is dead, but I don't really care because I have semi truck air horns.

 

Appreciate the feedback,replaced the horn with a new one all is well thanks!

 

Glad I could help.

 

unplug both horns
replace fuse , press horn button
If the fuse doesn't blow , plug one horn in at a time and press button
You should be able to figure out from there
