Driver's side door sensor not working.

[Audski27]

My keylesss entry hasn't been working. I took part the door handle and looked at the connections for the sensor. Zero corrosion. Also I swapped out with the rear drivers side sensor. Front sensor works in the rear fine and the rear does not work up front so it seems the sensor itself is fine. My OBD doesn't seem to pull up any problems. Where do I go from here?

Open up the door panel and check for frayed wires/insulation on the inside? There's a thread around with pictures of possible connectors and wires that need to be repaired.
