possible BCM problems

2003 SS, I believe I have a bad BCM because I've lost all courtesy info, and my A/C is on but no fan control, Service Vehicle soon alert, I'm thinking BCM, but could use some feedback

This is a long shot but check all electrical connections.. Youll get a "SVS" notice for a TON of things that could be unplugged or not grounded correctly..

Get checked for codes.
You might see a code starting with a "B" (Body), or "U" (Network Communications).
Narrow it down from there.
