2005 Deville Fuel door/ trunk latch fuse

In my 2005 Deville my fuel door and trunk latch will not work. I checked all my fuses and they are good. Is thee anything else that I might be missing. It says that their both on relays but dont think the relays are energizing. Where can I find the feeds for the relays which I think there coming from the same one feed.? Please Reply. Thanks!!!
