Well done Dennis! Your perseverance paid off and your posting/documenting of this problem will likely help another JeepGarage member in the future. Moderators should take note and put this thread in the TROUBLE SHOOTING/PROBLEMS/SERVICE forum.
On a side note you mentioned you took it to a dealer and the service manager, "reluctantly walked over opened door and shook the rubber covering door wire harness. Of course nothing changed. Said will need to tear into it remove door panel possibly dash to get to BCM. Will probably need a few days to figure it out." The service manager may have been trying a 1997-2003 C5 Corvette electrical gremlin quick fix. To make a long story short I owned a 2003 Corvette for 12 years (purchased new) and this generation Corvette has many gremlins but one notorious electrical gremlin was an electrical short in the wiring harness which travels through the accordion style rubber boot between the drivers door and the body. When your Corvette's electrical system suddenly goes haywire, windows don't work, HVAC don't work, computer makes car run at half power limp mode and much more the quick fix was to simply grab that rubber boot and twist it up until the car's electrical system recovers. By twisting it up you temporarily separate the electrical short and the car runs fine until the short reoccurs by opening/closing the door or if water gets inside the boot, or your simply driving down the road hit a bump and those two wires rub together and the electrical short happens. Sometimes that twisting quick fix could last for years and sometimes it would only work for a day or so. Eventually you have to open up that harness, find the short and tape it up. Chevy dealers to this day do not recognize this problem and don't know how to fix this particular gremlin. Thus owners go online and find the cure at the Corvette Forum.
Again congrats on a job well done!
