No, and no. I think you're going to find that the fusebox-mounted one is your 4-way (emergency) flasher, not your turn-signal flasher. You can go ahead and pull it, then see which of the two quits working, but I think you're going to find that you've just disabled your 4-way flashers, not your turn signals.
The turn-signal flasher is mounted up behind the dash next to the steering column. Easiest way to find it is to remove the lower cover, the black plastic cover above the pedals, and look up. It'll either be dangling from a 2-wire pigtail or clipped to a steering column bracket.
I agree that from what you describe of the symptoms, your turn-signal flasher seems to be on the way out, especially if you have the same symptoms regardless of whether you're signalling a right or left turn. (If only one side _or_ the other is affected, it'* probably a bulb problem.)
