1997 Ford Crown Victoria turns signal

You didn, t specify the problem, if a turn signal is flashing fast on one side a bulb is out, ck the front bulb and rear bulb on the side with the problem(compare to the working side).

If the turn signals are not working at all, try pushing the hazard button and wiggling it and see if the turn signals work. I have seen many of these switches go bad. By switch, I mean the lever that you push up and down, it is a switch. Maybe this will help.
