Drivers door switch
'04, cc/lb 6.0
I get in the truck and the dome lights come on, key the ignition and they stay on though they should go off, start truck and they still stay on until I reach 5 mph. Door ajar light is illuminated on the dash.
If the truck is off and I open the drivers door, the domes will come on, they will not come on if I open the other three doors.
I just replaced the switch on the drivers door and no change.
I held the trip button and started the engine. I kept tapping the button until "door 40" came up. When I opened the drivers door it would change from 40 to CO. When I opened the other doors, it would stay at 40. I did notice that once I had the drivers door open and completely off the latch and my hands off the door handle, I would move the door and it would then change from 40 to CO. At this point the latch switch is out of the picture. So if i move the door slightly open/close it would switch from 40 to CO when the door is nearly closed.
Is there another switch or sensor somewhere near the hinges?

Check for continuity in the switch wires as the door is opened/closed.
