While i had my ignition bad, every time i plugged in the flashers they blew out. I completely just gave up in the end. So, if your flasher goes out, check you ignition switch? does this sound viable? Anyone have a wiring diagram they could check?

Member Post nr. 218 Sacramento CA 81 320	The emergency flasher & turn signals are powered from fuse 15, which is in turn powered by the "start/run bus" (i.e. the "on" and "acc" terminals) coming off the ignition switch (along with fuses 12 and 18), so yes, if you have a defective ignition switch, it's very possible for there to be a related problem with the turn signal/flasher circuit. On the other hand, if you're NOT having issues with the other circuits powered from the start/run bus, I'd suspect that the two problems might be coincidental.......
