Have same problem as Jack Greider. So I have to remove push switch to remove hinge? How do I remove the upper hinge to check connections and is there a diagram if light harness assembly needs to be replaced.
In order to remove the hinge, you will need to remove the 1 or 2 screws that are in the hinge cover. Once you remove the Phillips screws you can lift the cover off. With the cover off you can check the wiring of the switch and also check voltage at the switch. With the lights not coming on with either of the doors open then the issue does not sound like a switch issue but more likely the light socket assembly 6621JK2003B.
