Diagnosing a Failing Escalade EXT Body Control Module

- ✔ Inoperative or intermittent power windows, door locks, or mirrors.
- ✔ HVAC blower motor not working or climate controls are unresponsive.
- ✔ The security system acts erratically, or the vehicle won’t start.
- ✔ Interior or exterior lights (headlights, taillights, dome lights) not working correctly.
- ✔ Airbag warning light is illuminated, often with a B1001 diagnostic trouble code.
- ✔ Communication errors between various electronic modules.
