Yes, the back seats in a 2004 Sunfire do fold down. There are straps on the back of the seats that are used to pull the seats down. The straps are assessable through the trunk of the car.
There should be a little lever behind the seats. Pull up on this and then the seats will fold down for you.

under one of the back seats after you fold them down. I think below the fuse box.
You can't fold down the seats, they are bolted in...
those were optional; open the trunk and look at rear of back seats; if you have a vertical split, you have fold-down seats, and heavy canvas-type finger grabs to fold the seat down at the top outside of each seat.
On Back of seats there is a plastic leaver, pull on leaver and push down seat.
Yes, it is legal to put child car seats on the fold down seats in the back of a pickup truck. You should follow the same instructions on the car seat for these types of seats.
