Restore Full Electrical Control to Your GM Vehicle
Are you experiencing a frustrating array of electrical problems in your 2004-2007 Chevrolet Express 3500 Van? Issues like erratic interior lights, non-responsive power windows, a malfunctioning HVAC system, or even a no-start condition can often be traced back to a single point of failure: the Body Control Module (BCM). This module acts as the central command center for your vehicle’s body electronics. When it fails, it can cause widespread and confusing symptoms. This OEM-quality replacement BCM, part number 15137395 (interchangeable with 15116066), is the definitive solution to restore your vehicle’s functionality and reliability.
Symptoms of a Failing Express 3500 Body Control Module
A faulty BCM can manifest in numerous ways. If you’re noticing any of the following issues, it’s a strong indicator that your Body Control Module needs replacement:
- ✔ Intermittent or total loss of power windows, door locks, or interior lighting.
- ✔ HVAC blower motor not working or operating erratically.
- ✔ The security system light is on, or the vehicle won’t start due to a security fault.
- ✔ Airbag warning light is illuminated, often with diagnostic trouble code (DTC) B1001.
- ✔ Wipers, horn, or exterior lights behaving unpredictably.
- ✔ A cluster of seemingly unrelated electrical DTCs stored in the vehicle’s memory.

Installation and Post-Install Notes
Installation is straightforward. For the 2004-2007 Express and Savana vans, the BCM is located in the center of the dash. Always disconnect the vehicle’s battery before removing the old module to prevent electrical shorts and help reset system memory. After installing the new module, some vehicles may require additional steps:
- Airbag System Sync: If the airbag light remains on, a technician will need to perform the ‘Setup SDM Primary Key in BCM’ procedure with a professional scan tool.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be needed to ensure correct brake light and traction control operation.
