Sounds like a BCM (Body Control Module) failure. The BCM controls everything you mentioned that is not working. HTH. -Jim

Behind the glovebox. There are two modules there attached to the same bracket. One is the Programmer for the HVAC system, the other is the BCM. (The BCM is the Module located closest to the firewall/engine compartment). It can be accessed by laying on the floor on pssgr side and removing the bottom panels under the dash. The Negative battery cable must be removed from battery FIRST before replacing the BCM!

Yes it was the CM. After it was installed I was told by my mechanic that Buick has a propitiatory code that they couldn't install so not everything is working like my airbags and others. Charged $700.00 for this. Will never go back to them.
