Hello and welcome to just answer, my name is ***** ***** master tech here to help. I annot see or hear your vehicle so I rely on your patience and input to my questions to better help you. I read your notes and have a question before we proceed. I will strive for a 5 star ratting and if I fall short let me know what I can do further. The first thing to do is check all fuses properly at both ends with either a test light oe volt meter. Then check the fuse-able links, these are the square higher amp ones in the use block under the hood. Let me know what ryour results are.

Ok what I would like you to try is locate the window relay and swap it with another that looks the same and try that.
