I have a LS P7010C that has an interesting problem. Turn ignition on, radio comes on. Turn on hvac blower, or lights or any other accessory and it turns off the radio and no longer has positive voltage to the hvac/radio/lighting fuse block. Does anyone have wiring diagrams or an idea where to start? I already tore out the hvac harness and checked it for shorts. None found and with stand alone power the blower worked fine.

That sure is a strange one. I don't have a diagram for you but it presents itself like there is another controller in the system killing power to everything.
Seems like there is a lot more electrical issues happening all of a sudden.

Agreed, I think there must be a relay giving power to the accessory fuse block and it may have some sort of protection circuit built in. Was hoping someone would know where those things would be to avoid having to tear apart the whole interior.
