Is your Chevrolet Express van suffering from bizarre electrical issues? Flickering lights, malfunctioning power windows, or strange warning messages can all point to a failing Body Control Module (BCM). For a hard-working vehicle like the Express 3500, downtime isn’t an option. This isn’t just a replacement part; it’s a complete, ready-to-install solution designed to get your van out of the garage and back on the job, fast.
Common Symptoms & Your Solution
A faulty BCM can create a host of frustrating problems that seem unrelated. If you’re experiencing any of the following, this pre-programmed module is the definitive fix:
- Power windows, door locks, or mirrors working intermittently or not at all.
- Interior or exterior lights behaving erratically (staying on, not turning on, or flickering).
- Security system issues or a vehicle that won’t start.
- False warning lights on the instrument cluster (e.g., airbag, ABS).
- Communication error codes (U-codes) when scanning the vehicle.
Instead of buying a used module that requires an expensive trip to the dealership for programming, our BCM arrives flashed with the latest GM software and perfectly matched to your vehicle’s VIN. This eliminates the guesswork and extra steps, saving you both time and money.

Expert Insight: The Programming Advantage
Many people are tempted to pull a BCM from a junkyard vehicle to save money. However, a BCM is not a simple swap. It’s the central hub for your vehicle’s body electronics and is coded specifically to the features and VIN of the original car. Installing a used, un-programmed module will, at best, not work correctly and, at worst, can prevent your vehicle from starting entirely. Our service handles the critical programming step for you, delivering a part that communicates seamlessly with your vehicle’s other systems right out of the box.
Post-Installation Procedures
While this module is pre-programmed, certain vehicle systems may require a relearn or synchronization procedure after installation. Please be aware of the following possibilities:
- Airbag System Sync: If the airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional scan tool.
- Brake Pedal Position Relearn: A recalibration of the brake pedal position sensor may be needed to ensure proper brake light and traction control function.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
How do I provide my vehicle’s VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot program and ship your Body Control Module without it. You can typically add it as a note during checkout or send it to us in a message referencing your order number.
Is this BCM difficult to install?
The physical installation is typically straightforward, involving disconnecting the battery and swapping the module. However, the location varies by vehicle (e.g., under the dash, behind the glove box). The key benefit of our product is that the complex programming is already done. Some models may require post-install relearn procedures as noted above, which may require a professional scan tool.
Will this fix my exact problem?
This BCM will resolve issues directly caused by a faulty module. While the symptoms listed are common indicators of BCM failure, we always recommend a proper diagnosis by a qualified technician to rule out other potential causes like wiring or sensor faults before ordering.
Do I need to return my old BCM?
No. This product comes with no core charge. You are free to keep your original module without any extra fees.
What if my part number isn’t on the list?
The provided list of part numbers is extensive. If your number is not listed, please contact us with your vehicle’s VIN and original part number. We can verify compatibility to ensure you receive the correct component for your vehicle.
