1994 Pontiac Firebird blinkers

My blinkers didnt work for the longest time. They would just stay lit up. I would signal left and the arrow would stay lit up on the dash and outside the car, but they wouldnt flash. Same thing for signaling right. I changed the flasher relay and now the left flashes but very slowly and the right does the same thing it had done before, just stays lit up. What could the problem be? And the bulbs are fine.
