Default Rear Drivers Side Door still has no power

Friends
My 2003 has a drivers side rear door that has no power.
To date I have:
Moved the window switch to insure it was not faulty - It worked fine.
Purchased a new harness for that door and installed - still no power
Purchased a new window actuator and plugged into both original and new harness - No Work
Checked all the fuses that say LR Door - all fuses good

Door will not lock/unlock, no window function and no lights either in bottom of door or ash tray

Anyone have any additional ideas......I'm open to all suggestions
Thanks

This is just what I reckon. Haven't dealt with it myself. Is there a grounding point for that door? Probably a broken ground wire, or some corrosion on the bolt. Search for door wiring diagrams, see what you find.

You need to get yourself a digital multimeter (Harbor Freight has them for a few bucks or even free with the right coupon) and a wiring diagram of the rear door and troubleshoot it the correct way instead of throwing parts at it.

There are alot of fuses in this car and they are not marked as clearly as I would like. My money is on a fuse or fusible link that is open. Sorry that I can't be of more help...
