Turn Signal Problems

Ok guys, I just got a 1992 Olds 98 Regency. When I first got this none of the blinkers worked at all so today I decided to pull the airbags and take a look at the switch. Lever wasn't secured to the switch and was very loose. I tightened it up and was able to get the Right signal working. Left signal comes on but doesn't flash just sticks lit up. Also checked Hazards and they work fine. Any idea on where to start looking to fix this?

Are all the bulbs working on the left side? A bad bulb would cause it not to flash.
