look for a Cadillac Esclade. Same thing. The seat heaters run thru a CCSM module, along with two blower motors per seat ( fronts do anyway ), and a drivers seat module. You are correct about some 5v control stuff. We had a Caddy in the shop the other day, and the control stuff runs thru the BCM before it gets to the CCSM.
