Wire repair in left front A pillar is the repair bill I got Problem is the door unit is dead, can't roll up windows, lock driver door, and access any controls on door.

You need a new repair shop. Hope that wasn't a dealer. Don't want to know that,spare me.
They need to see if a scanner can communicate with the door module. Assuming you have one, and that sounds as though, what your referring to.
If they found issues in the A pillar,e.g. left window post or frame,it would have been taken care of,or why mention it.
Did you get it back not working?
Only A pillar wires would be for overhead console feed?
If scanner can not actuate window for any reason,you go to wiring diagram and work through the various circuits pertaining to windows,locks etc.
They may not have a data base they subscribe to,so no wire charts, or don't want that type of work,it takes too long to figure out and don't feel comfortable telling you how many billable hour it will take. That is most every vehicle owners problem. Shops can fix these things,but can't charge for it. If they spend the time ,they go out of business.
