I have a 2010 Escalade, I lost all function to drivers side seat, heat in passenger side, adjustable fuel and break, and steering column adjustment. All these functions are connected thru the drivers side seat memory module. The problem ended up being a plug on the memory module (the circuit card that remembers all the seat, pedal, steering positions, and seat heat monitor. So the big clues! All the devices are effected, intermittent or no problems until it quits. I had no issues.. I checked all fusses, disassembled drivers side seat, found no wire chaff issues or seat heater issues, Cadillac did a great job with wire mounting and wire movement areas. The module can be clearly viewed by looking under the driver side seat, mounted under metal support for cushion. If you have separate issues, look for that devise wiring and fuse.
