Are you battling strange and frustrating electrical problems in your Chevrolet Express or GMC Savana van? Issues like flickering lights, malfunctioning power windows and locks, or a security system that acts up on its own are often signs of a failing Body Control Module (BCM). The BCM is the central computer for your vehicle’s body electronics, and when it fails, it can cause a wide range of seemingly unrelated symptoms. This replacement BCM, part number 25934762, is the reliable, plug-and-play solution to restore your van’s functionality and peace of mind.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors not working correctly.
- ✔ The security system or keyless entry failing or acting erratically.
- ✔ The instrument cluster displaying incorrect information or warning lights.
- ✔ Intermittent no-start conditions where the engine cranks but won’t fire.
- ✔ The radio or climate control system turning on or off by itself.

Installation and Post-Install Notes
Installation is typically straightforward, as the BCM is located in the center dash area on Express and Savana vans. While this is a plug-and-play module, some vehicles may require additional steps after installation:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure may be needed using a professional scan tool. This is only required if the light appears.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure proper brake light and traction control operation.
Always consult a factory service manual or a qualified technician for vehicle-specific guidance.
