Default 2003 BMW Z4 E85 Electrical Issues

Weird electrical issues started happening last week with my 2003 Z4.
I have checked fuses behind the glove box, and battery and alternator were tested and are good. Amp to radio does turn on and I can feel it get warm after being on.
Here are the symptoms:
1.) Radio display turns on, changes channels, etc. but no sound.
2.) Turn signals work, but dash indicator lights do not.
3.) A/C will not blow cold, only warm
4.) Sometimes, after I remove the key from the ignition, the "key in ignition" warning beep will not stop, even after closing the door.
5.) Remote locking will not work while the warning beep is going off
6.) Airbag light is constantly lit on dash.

All this happened last Monday. Got in the car to go to work and noticed all the problems. Anyone have any feedback on where to go from here? I have checked fuses behind the glove box, and battery and alternator were tested and are good. Amp to radio does turn on and I can feel it get warm after being on.
Thanks in advance guys this is driving me nuts
