How to troubleshoot no door chime, no turn signal indicator and no power to ster

What is your question?

My door chime was intermittent on working the last months or so and then 11/25/18 I lost power to stereo and my turn signal indicator doesnt chime anymore and now the door chime for open door, seat belt and key in ignition doesn't work at all. All fuse are good, I've tried disconnecting batteries for reset(the only thing that corrected was dash notifications were a little brighter with proper notification for a couple hours). All of those things are on same circuit, plus amp for bose systems. Chevy recalled this same issue with next generation after mine. Identical stuff. Any suggestions. I have pulled fuses and put them back in (1 guy got his to reset from that) Im pulling door panel off and checking speaker door switch and anything else that I can handle today.. Thanks
