start bu checking the flasher unit & relays
No it means you have your left blinker on. The right bulbs have nothing to do with the left blinker. An incandescent bulb either works or it doesn't. There is no dying out.
If your "left blinker" is on, to change it, "push up" the blinker arm that is on your steering wheel. If your right blinker is on, push the arm down to change it to the right blinker. This works on All Cavaliers and most other cars made in the U.S.
change the bulb
Replace the tail light bulb from inside the trunk after pulling back the carpet. This should probably fix your blinker too.
Sounds like the light bulb is either loose or burned out in the dash. Replace it.
