I hav a 2003 Pontiac Sunfire, my left tail light and rear turn singal dont work. Anyone know what...

Yes It may be a wiring Prob or the sock es them self not making contact with the bulbs.Easy why to tell Get a can of white grease, And spray into socket if lights don't work after that. Sockets could be bad or your wires are grounding out.

Possibly a fuse, loose wire, bad socket, broken wire.relay etc.
Pick and choose what to check first.I would use a test light and start at the socket after checking the fuse.Note these two lamps are on different circuits.Turn signal and brakes are connected.

The Sunfire/Cavalier of those years have had issues with the sockets for the taillamps the contacts in the socket are loose and the bulbs overheat and burn into the plastic housing..
GM has issued a replacment socket assembly but you will have to purchace them at the dealership, and make sure you replace the bulbs again also..
I worked at a GM dealership for years and have seen it quite often..
