Emergency Flasher Problem

Well, I just replaced my emergency warning flasher bezel because the red cover had been remove (exposing the bulb). Otherwise, it was working fine. So when I replace the bezel, it sparked as the bulb unit touched the spring and bezel. Now the light doesn't work. So I'm assuming I shorted something or blew a fuse.

For starters, which fuse operates the emergency flasher?

Side note: All other instrument panel lights and exterior lights still work.

I don't know, but i'd just try to replace the fuse. The are under the driver's side dash... and a mega pain in the @$$ to get too.

I believe the 4 ways are hot constantly if Im not mistaken. As to the light...did you see if you killed the bulb itself ??? its the same as the cluster bulbs...

Yeah, I tried a new bulb - no luck. What's meant by "the 4 ways are hot constantly" - no fuse? Would that mean I shorted something out?
