You may have to stand on your head to finds it under the dash.Do the signal lights work and just the flasher that don't or is it both the signals and flashers?
If one works but not the other you likely have a bad flasher but if neither work you could have 2 bad flashers or other problems. It won't be bulbs if one works and not the other. Signals and 4 way use separate flashers.


Clean it, if it's Dirty. Oil it, if it Squeaks. But: Don't fix it, if it Works!
