2009 Tahoe harness has power with battery neg disconnected and power to ground short issue.

[Reecedakid03]

the driver door (open/closed) sensor is integrated into the door lock actuator, so probably need to replace the actuator

Do you think that being bad would kill my driver door switch entirely? I tested and there’s power getting to the window switch but I don’t have amy diagrams to check which is supposed to have ground or power. also swapped in my switch from my other truck and still nothing. All other doors work from their switch panels. I can’t adjust mirrors, unlock or lock, or anything. The truck doesn’t even register the door is open or closed anymore. Im just baffled this truck can have this many electrical issues at this point.

the actuator causing all those other issue's is unlikely, you could unplugg the actuator to verify, but I would suspect at some point while messing with the door either you have a bad connection or blew a fuse in the process if the battery was still connected, in which case I would check each and every fuse. you can probe them from the outside with a meter on the 2 metal tabs, you do not have to pull each fuse.
