I have a turn signal issue with a 2003 Lincoln Navigator.

Left and Right turn signals work intermittently. Sometimes normal, sometimes nothing, most of the time just a few clicks before turning off. The flashers operate normal with the hazard lights on and everything else operates normal too.

Is it the signal switch, relay, or something else?? I'm not sure where to start. Thanks for any help.

Here's a link to the parts I'm suspect of

It's very possible that it's the flasher. Sometimes the switch contacts get dirty and they will do that but mostly not at all. You could try spraying contact cleaner down next to the hazard button and operating the hazard switch a few times when you spray and see if that helps.
