I have 17 frontier kingcab sv4x4 dr door ajar lite on always? Checked and replaced jam switch on both sides lite still on? Disconnect harness drivers side still on, is there a fuse or relay or ground? Help.. temporary pulled bulbs out of cargo lite.

That vehicle might still be under warranty. If so, that's the easiest route to go (bring it back to the dealer).
You could check the factory service manual for the wiring associated with the ajar light. The 2017 manual isn't available, but 2016 should be the same. I'm surprised disconnecting the switches on both sides doesn't fix it.

LOL...a 2005 manual will probably be the same.
