Numerous issues? Bad Ground?

hey guys own a 2001 Regal GS. When i got it, i noticed it has a few small issues.the horn dont work, drivers side heated seat dont work, airbag light is on. NOW here is what i done so far:
-replaced the horn, didnt fix it
-replaced drivers seat with a known good one, didnt fix it. *NOTE passenger side works fine*
-covered the airbag light up with black tape, didnt fix it.
-replaced clock spring, didnt fix anything
-replaced heated seat switches...twice...didnt fix anything

So now im thinking maybe a bad BCM? Ground? Are there any known bad ground locations on this vehicle? I also did a negative wire upgrade 0 gauged from the batter to the body and to the engine.

Have you checked the fuse for the horn?

On the heated drivers seat, make sure the harness under it isn't broken somewhere.

Have you scanned the car for codes? Might be able to narrow down the airbag light that way.

Check the ground that attaches to the transmission bellhousing. Should be up front on a stud.
