On my '97 it's under the dash, incorporated into a control assembly which cannot be repaired. You have to replace the whole assembly and it's expensive. Look under the dash just the the right of the steering column and find a small black box, about 5 inches square and about an inch and a half thick. If yours is the same as mine, that's it.
Replace the flasher relay if none of them are working.
did you try your fuse panel
It has 2 flasher relays. One for the turn signals and one for the hazard lights. The turn signal flasher is located on the drivers side, under the dash, driver side of steering column, mounted in the fuse panel.
Should just unplug
I have a 1996 Grand Marquis. If one of the brake lights goes out the signal on that side flashes faster. I would check the brake/tail lamps.
