Hi Scotty huge fan. I been having some issues with my power windows for a while on my 2011 avalanche LT 5.3 L Automatic, 170000 miles. My driver side power windows don't work. I know the motors work because they were stuck halfway and I was able to jump them back up. Interesting enough the passenger side windows work but not from the master switch. So I replaced the master switch thinking that was it, bought a new one and replaced it and it didn't solve the issue. I got 12.3 volts going to the switch. The mirror switch is also affected along with seat warmer switch (no power). I also experience static coming from the speakers when I turn on my blinker signals. I honestly think that my fuse box is going bad but didn't see any burned or corroded wires. I would really appreciate your opinion about this.
