So my hazards just stopped working out of no were, I tested all my fuses in the engine bay and they were all good.(I used a live wire tester) so after I checked that I went to check the fuses behind the kicker panel inside and non of them responded, acted like they were all dead with the keys i. The ingnition. How do I properly check these?

 

If I'm not mistaken the flashers are the metal ones. What year is your mustang?

 

Starch that it's fuse number 6

 

If you don't have an ohm meter look at the fuse and see if there is a break in the metal on the inside. If you see a gap then it is blown.
