On my vehicle listed above (LS model) the interior lights decide to not turn on. Everything from the windows, air conditioner, radio and dash lights will not turn on. It has been loosing power here and there at a stop light and accelerating. The hub bearing on passenger side does need to be replaced. Can that have anything to do with that? I have checked all fuses under back seat and under hood. What else can it be?

A bad hub will not interfere with the interior lights. The common reason for the interior lights to fail is that the dimmer control burns out or gets turned down to off.
It is part of the headlight switch. Not hard to change, remove the access cover at the end of the dash, reach in and press the tabs that release the switch from the dash panel. Pull the switch out. Disconnect the connectors. Reverse the process to install the new switch.

It was the mega fuse under hood. Had a blown 125 amp replaced it with a 175 amp. And everything back to working.

I would replace the 175 amp with a 125 amp, ASAP, you do not want to burn up anything if there is a problem.

Good job on the repair.
