Bulb is blown. Replace bulb.
Bad earth connection at light cluster?
Sounds like the light bulb is either loose or burned out in the dash. Replace it.
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.
Honestly? At the junkyard, or on eBay.
There might be a break in the wiring.
the light burnt out and you need a new one?
Usually a sign of a bad ground connection or corroded contacts on the light socket. In other words a poor connection at that blinker.
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.
Check the bulb, it could be blown.
You probably have a turn signal or light that is burnt out
It means that a bulb has burned out!
