Hey Everyone. Having a weird electrical issue.

2006 R53:

• Front and Rear Wipers on regardless of stalk position (stop when I take key out)
• Auto Climate Control Shuts off
• Airbag light came on
• Radio Turns off, Can turn back on but stays on after ignition off (manually turn off)

All started simultaneously and seem related.

Things I have checked for diagnosis:

Battery checked, Interstate replaced July 2023 (12+ volts when off, 14+ volts with engine running)
Clean battery ground cable, engine mount ground cable, underhood fuse box ground
Check BCM (no corrosion present on connectors), deoxit on connections
Check 42 pin connector on driver side (no corrosion present, deoxit)
Check underhood fuses, pulled all out and cleaned (no corrosion)

At a loss for what next to check. Thanks in advance.
