Restore Your Vehicle’s Electrical System with a Plug-and-Play Solution
Are you battling strange and frustrating electrical issues in your GM vehicle? Flickering lights, malfunctioning power windows, a security system that acts up, or an intermittent no-start condition can all point to a failing Body Control Module (BCM). For a workhorse like the Express 3500, these aren’t just annoyances—they’re problems that cost you time and money. This replacement BCM is the definitive, hassle-free solution to get your vehicle back in reliable, working order.
Common Symptoms & Your Solution
A faulty BCM acts like a glitch in your vehicle’s central nervous system, causing a wide range of confusing symptoms. If you’re experiencing issues like power locks not working, incorrect gauge readings, interior lights staying on, or diagnostic trouble codes related to communication errors, the BCM is the most likely culprit. Instead of a costly and time-consuming trip to the dealership, this module arrives at your door pre-programmed specifically for your vehicle. We use your VIN to flash the unit with the latest, most stable software updates from GM, ensuring it integrates seamlessly with your vehicle’s existing systems. This is the professional-grade fix that gets you back on the road with confidence. Using a Programmed Express 3500 Body Control Module is the smartest way to ensure a correct and lasting repair.
An Expert’s Note on BCM Replacement
The Body Control Module is the command center for nearly all your vehicle’s non-engine-related electronics—from the horn and headlights to the power seats and radio. It’s not a simple component you can just swap out. Each BCM is programmed with specific software that matches the options and security protocols of the vehicle it was built for. Installing a non-programmed module from another vehicle will, at best, not work correctly and, at worst, can prevent the vehicle from starting altogether. Our VIN-programming service isn’t just a convenience; it’s a critical step that makes this a true plug-and-play repair, saving you from hundreds of dollars in dealer programming fees.

Post-Installation Requirements
In some cases, additional vehicle-specific relearn procedures may be necessary after installation. These often require a professional-grade scan tool. 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 is required to sync the systems.
- Brake Pedal Position Relearn: A recalibration of the brake pedal position sensor may be needed to ensure proper function of the brake lights and stability control systems.
We provide this Programmed Express 3500 Body Control Module as the core component of your repair; however, always consult a factory service manual for procedures specific to your vehicle.
Frequently Asked Questions
What exactly does the Body Control Module do?
The BCM is a computer that controls and monitors most of your vehicle’s body electronics. This includes power windows, door locks, interior and exterior lighting, wipers, the security system, and more. When it fails, it can cause a wide variety of seemingly unrelated electrical problems.
Why do you need my VIN number?
Your Vehicle Identification Number (VIN) allows us to access the specific software and calibration files for your vehicle’s exact build, including its engine, transmission, and optional features. Programming the BCM with this data is essential for it to function correctly.
Is this a difficult part to install?
The physical replacement is typically straightforward. The BCM is usually located under the dashboard on the driver’s side. The main challenge is typically the programming, which we handle for you. However, some vehicles may require additional relearn procedures after installation, which may require a professional scan tool.
What if my original part number isn’t on your list?
The provided list of part numbers is extensive. If your number is not listed, please contact us with your VIN. GM often consolidates multiple old part numbers into a single new one, and we can verify compatibility for you.
Will this fix my ‘Service Airbag’ light?
If the BCM is the source of the communication fault causing the light, it may. However, after installation, the airbag system (SDM) will need to be electronically ‘synced’ with the new BCM using a high-level scan tool to turn the light off. This is a standard security procedure on GM vehicles.
