You have parasitic draw, but disconnecting the fuse box is not the way to find it. This is

It probably blew a fuse.

Flasher unit would not cause one side only to stop working but instead check the switch, wiring, connections and both bulbs.

A little used hazard warning switch is often the cause of strange or unusual flasher behaviour. A couple of minutes of rapid operation often works.

Easy way to find the location of the flasher unit: Turn on either the RIGHT or LEFT indicator, and listen for the click under the dash. When you find the source of the click, THERE'S THE FLASHER UNIT! :)

Find your turn signal flasher under the dash, you should be able to hear it click with the turn signal on. The flasher plugs in and is easily replaced. If you go to a parts store first you can see what yours looks like.

Check the relay and the flasher

And all lights flash? Is this with or without a trailer and its lights connected? LED lights installed?
Many times when there is a slow or fast rate that the signals flash its due to a chaneg in current being drawn. Either from hooking up trailer lights or changing the bulbs to LED. LEDs will draw less currenct and more lights more current.
There are electronic flashers that automaticaly adjust for different current draws to make the lights flash at a normal rate and they plug right in to replace your stock mechanical flasher.

you will need to inspect all of the left side blinker bulbs one of the bulbs that is supposed to blink is bad my buddy has a caviler that had the same problem one of the bulbs ended up being bad it was the rear drivers side bulb. there is also a flasher relay locater under the dash that tends to go bad just listen for the ticking and replace the flasher the flasher costs about 8 bucks at you autopart store ask for a flasher relay. i hope this helps.

Check all turn signal bulbs, you probably have one burt out.
