One thing I didn't mention is that the drivers door control module was replaced at a authorized repair facility with a new gm original part with no improvement or changes with the problem. Of corse there is no return allowed on electrical parts so she is out close to two hundred bucks on that deal. She was quoted a more reasonable price from this facility but ended up losing because if the dealer would have done the work the money wasted on the part could have gone towards labor at finding the problem at the dealer. I double checked everything today with all the wiring, fuses, and grounding blocke to no avail. I find absoulutely no corrosion anywhere so I put it all back together and put the battle on hold for another day. I still don't understand why none of the switch illumination lights work on the 3 doors that aren't functioning. If they all have different grounding blocks it seems that at least one or more of them would be working. Only grounding block I don't seem to find is RR door. Do the rear doors share the same grounding block that is located under the rear seat close to the left side or is there anonther one somewhere on the right side for the RR door? I have declared war on this problem but I can see I may need some reinforcement troops to prevail. Any help will be apprciated.
