Ok! Finally go to finish up fixing my 2005 T&C 3.3L - Turns out sometimes overlooking the most simple things, fix it first. After replacing the PCM and FCM, I found out it was in fact the passenger side sliding door wire harness that rides in the track on bottom of the door. The harness had been broken, smashed, and and severed. Door got shut on the wiring harness and ruined the wires. Unplugged the harness from the base of the seat belt pillar on the passenger side, and tried the key in the van...PERFECT! IT WORKED!! Key fob came back online, CD player, DVD player, Dash cluster....ALL came back online. The van works like a dream and we now have a great van that we bought for $200 US dollars plus the cost on one computer setup (not actually needed) for $140.00. A very worthwhile purchase at $340.00 for a van in great shape. (Van was sold to us for scrap because it would not work).
Bottom line, the simple thing to fix the van was that wiring harness for the door. It is amazing just how much of the van the door's wiring harness disabled! The van was essentially DOA. For $5.39 for the harness from our local salvage, we scored big!
