Is there a relay under the hood of a 1992 Pontiac Grand Am SE that would make the turn signals not work even if the fuses are good?

I had a 1992 Grand Prix LE the turn signals did not work and the fuses were good. Look at the swith on the steering collum try pulling the bright swith with the turn signal on. I did that on mine and they started blinking I replaced the swith and they now work fine.
