Window Problems

[92Rustang]

Hey guys I need a little help. 03 tahoe LR window not working. I'm not getting power to the motor. I have tried a new motor and still nothing. Pulled out the volt meter and have power at the switch. When toggling the switch I get no voltage at the br or blue wires. I have replaced all of the switches including the master drivers switch. I'm lost. I have a wiring diagram and see two ( bussed elertical centers) but I have know clue where to find them.

You are better off with a test light when testing motor circuits if you have one. Let me try to understand where you are at here. You have B+ on terminal A and a good ground on terminal E? Also you have no power on Terminals F or G when working the switch? Do you have Ground @ terminals F and G at all times or is there nothing there? What value do you have at terminal D?

I will look tonight or tommorow. I was reading 12volts I think on D? If F and G are Dr. Blue and Brown I would read .1 volts when working the switch.
