2013 iMac running great, except Bluetooth

From ventura and older to Sonoma 14.5 (23F79). There is no bluetooth. (even no plist files) Wifi Works great. I even downloaded older systems but there is always problem with bluetooth module. I even replaced module with imac 2011 wifi module. Is this problem with firmware, or hardware on mainboard? I have latest OCLP and iv done almost everything like PRAM reseting, etc.
