oledaniel, I think your Tahoe has a body control module, which is a separate computer the manages many of the lights, door locks, power to radios, etc. For example,a shortened out switch could be sending a door open condition to the computer, which is then not allowing a lot of other things to happen as 'normal' conditions. I think the only way to really narrow it down would be to have one of your local shops hook it up to an analyzer. Around here Autozone does it for free. Otherwise you'd be replacing and checking a whole lot of components. Also, your local library may have the wiring diagram in a Repair manual, get a copy of it and follow the flowchart. Sorry I have nothing more precise for you. Good Luck and let us know what you find out.
