Chrysler Repair: 2000 Intrepid rear door wiring, haynes shop, power circuits

Question
I have an '00 Intrepid and I am having a problem with the rear - drivers side door.  I short, I can't unlock it either with the power lock switch or via lifting the button,  I also can't lower the window.   My initial feeling was that the lock was broken and I needed to figure out how to get the panel off without opening the door, but I recently discovered the window issue and now feel that it might be electrical in nature, like a wiring harness to the door being disconnected.

Answer
Hi Mike,
I agree with you that the problem is likely related to an electrical open in the wiring from the left side of the body to the left rear door. With power door lock and power windows I believe that the motions of the locks and the window glass are all via electrical power circuits. The fact that both the window and the locks don't function makes me suspect a common mode failure, specifically the ground return wire from both of the circuits being open.
I am quite out of date on the specifics of the '00 Intrepid because I only have the '94 Chrysler shop manual and the '94-7 Haynes shop manual. The Chrysler manual identifies the ground lead for both the window motor and the door locks as a 20 gauge yellow wire in what is known as the M2 circuit. The drawings show a harness coming from the instrument panel and running along the outer edge of the floor under the left front door opening and that a subharness splits off at the common pillar between the two doors and  thru a cut-out in the inner piller which then goes into the rear door at the front inner edge of the door with a disconnect inside the door for that harness. It appears to have 7 wires (8 available pins) of which #2 is the yellow common ground wire. I would suspect that the wire is fatigued due to the door being opened and closed so that althought there may be power to the door locks and the window motor there is no return for the current to the - post of the battery. I suspect that if you remove the door panel you can manipulate the electrically operated latches so as to open the door and then see if my theory is correct. The body chapter of both the Chrysler and the Haynes manuals give a fairly good idea of how to remove the trim panel for the rear door.
If there is a fairly large local library where you are you might find one of these manuals in the auto repair manual section. Alternatively, I could copy some of the relevant pages and mail them to you. I can't be certain that they will apply exactly to the '00 model but the chances are good that they do. Another source for used shop manuals is eBay, and you can buy new shop manuals directly from Chrysler at a cost of around $80 (1-800-440-572-7240 is the Dyment Distribution Co.). In any case, the door trim panel is secured both with a few screws and some hooks which release by pulling straight up on the panel once the screws are removed. Don't force anything for fear of breaking the panel or the hooks.
Let me know what manual resources you can acquire or whether you need me to do some xeroxing at cost (four cents per page) plus postage).
