Diagram shows the power distribution for the L/H bat 2 bec fuse and if the IPC/HVAC BATT fuse that is draining, disconnect the HVAC control assy to test if it is the one causing the problem or the IPC (instrument panel cluster)

Did you find anything out on your dilemma? I am having kinda the same issues, gauges drop to zero while driving, intermittently. Replaced the ignition switch, checked and verified every fuse while setting still and everything working fine. Scanner says no codes. Only seen it error while driving/moving. Above schematic will help, didn't think of HVAC module thrown into the mix.
