Are you battling persistent and unpredictable electrical issues in your 2004-2007 Chevrolet Express 2500 Van? Symptoms like malfunctioning power windows, erratic interior lights, a non-responsive HVAC system, or mysterious warning lights on your dash often point directly to a failing Body Control Module (BCM).

Installation is typically straightforward, with the BCM located under the center of the dash in Express and Savana vans. While the unit is designed for simple replacement, some vehicles may require post-installation procedures. If the airbag light remains on, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ function. Similarly, a brake pedal position sensor relearn may be necessary on certain models. Always consult a service manual for vehicle-specific instructions.
