Are you battling frustrating electrical issues in your GM van or SUV? Flickering lights, malfunctioning power windows, a dead instrument cluster, or a security system that prevents your vehicle from starting are all classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can cause a wide range of confusing and intermittent problems. Restore full functionality and peace of mind with our pre-programmed BCM, a direct-fit solution for your vehicle.
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We take the hassle out of the repair by programming the module to your vehicle’s specific VIN before it ships. This ensures compatibility with your vehicle’s options and loads the latest software updates from GM, often resolving issues that were present even with the original factory part. Simply provide your VIN at checkout, and we’ll handle the rest.
Symptoms of a Failing Express 1500 Body Control Module
- ✔ Intermittent or non-functional power windows, door locks, and mirrors.
- ✔ Erratic behavior from interior or exterior lights (staying on or not turning on).
- ✔ Instrument cluster gauges behaving abnormally or not working at all.
- ✔ Vehicle security system faults or a no-start condition where the engine cranks but won’t fire.
- ✔ Horn sounding unexpectedly or not working when pressed.
- ✔ Inconsistent operation of the radio or HVAC controls.
- ✔ False warning lights on the dashboard, such as the airbag or ABS light.
Installation and Post-Install Notes
Installation is straightforward for those with basic mechanical skills, typically involving removing a few dash panels to access the module. Once installed, most functions will be immediately restored. However, please be aware of the following potential procedures:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system. This is only required if the light appears.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be necessary to ensure correct brake light and traction control operation.
Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that manages and controls electronic accessories like power windows, locks, lights, the security system, and the instrument cluster. It acts as a central hub for these functions.
How do I provide my VIN for programming?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship your part until we receive this information, as the programming is essential for the module to work correctly.
Is this BCM difficult to install?
For someone with moderate DIY automotive experience, the installation is manageable. The BCM is typically located under the dashboard on the driver’s side or in the center dash area. It involves removing some trim panels and unplugging the old module to plug in the new one. No special tools are required for the physical swap.
Do I need to return my old BCM?
No, there is no core charge for this part. You can keep your original module.
What if my airbag light comes on after installation?
This can happen occasionally. It means the new BCM needs to be electronically introduced to the airbag system (SDM). A repair shop with a professional-grade diagnostic tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this and turn off the light.
Will this part fit other vehicles besides the Express Van?
Yes. This BCM is used across a wide variety of GM vehicles from this era, including the Chevy Tahoe, GMC Acadia, Cadillac CTS, Buick Enclave, and many others. Please refer to the detailed fitment list on this page to confirm compatibility with your specific make, model, and year.
