My wife has a 2003 Cavalier, and her front and rear driver's side turn signals are out. Her driver's side rear light went out a year ago and I replaced the bulb and it's worked fine till now. I know there is a recall that we haven't gotten fixed for the rear light, but was curious as to why both went out on one side. Do I need to get new bulbs? Is there a specific fuse I can replace?

I have a 2005 Cavalier, and had a 1999 Cavalier before that. I wish they still made them.
Thanks,
Mike
