I'm not familiar with your Sunfire but
on some cars you have to remove the headlight assembly to access the
turnsignal bulbs.

Some cars if you need to go underneath the front bumper  and remove the
black splash shield or perhaps the wheel well liner can be unfastened to
gain access to the turnsignals.

Most GM cars the turnsignal sockets twist one way and then you pull it
straight out.

Hope this helps.

good luck.....
