I was going through this with my "new to me"seats. I don't think you can really get the smell out of seat foam and stuff, it seems impossible to really get in there. Carpet should be easier. I would strip it out and and wash it down with a hose, brush and cleaner of choice. and air out for several days. Then take it from there. I used baking soda and vinegar in a spray bottle. The seat covers came out OK, the seat foams are still a bit whiffy. The idea is to kill the source of the smell, not mask it with febreze type stuff. BTDT.

Also after you strip out the carpet you can check the under carpet pads/sound deadening for stink too. My early car has some thick padding down by the rear quarters.
