My driver side passanger door doesn't give any indication that its open. No dome light, no "door ajar" on the DIC, nothing. But the window will roll down no problem. I'm at a loss. Any ideas?

The door-open sensor is separate from the window and the lock/unlock solenoid circuits. If you have a meter, monitor the light blue/black stripe wire in the door harness. It could be broken due to flexing at the hinge line, or the latch assembly could be corroded and just need some lubrication to free up the latch sensor switch. Or the black ground wire to the sensor could be open.

At the door latch (pull the interior panel) or at the hinge line (inside the protective sheath). Getting at the wires at the rear fuse panel where they get passed through to the BCM is more difficult to explain. Assuming you have a meter and are going to troubleshoot it, many folks don't know about the "stick a needle/pin through the insulation to check a wire where you can't get to the connector" trick.
