Is Your GM Truck or Van Experiencing Bizarre Electrical Problems?
If you’re dealing with flickering lights, malfunctioning power windows, or a security system that has a mind of its own, a failing Body Control Module (BCM) is the most likely culprit. The BCM is the central command center for your vehicle’s body electronics, and when it starts to fail, it can cause a cascade of frustrating and seemingly unrelated issues. Don’t let these electrical gremlins sideline your vehicle. This direct-fit replacement BCM is the reliable solution to restore full functionality and peace of mind.
From the Diagnostic Bay
We had a 2006 Chevy Express 2500 work van come in that was killing batteries overnight. The owner had already replaced the battery and alternator, but the problem persisted. A parasitic draw test showed a significant current pull even with the key off. After isolating circuits, we traced the draw to the BCM. It wasn’t properly putting other modules to sleep, causing the drain. We installed one of our VIN-programmed BCMs, and the draw disappeared completely. The van was back on the road the next day, saving the owner from lost work and the high cost of a dealership repair.
Symptoms of a Failing GM Body Control Module
- ✔ Erratic or non-functional interior and exterior lights (headlights, dome lights, dash lights).
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ Vehicle security system issues, including random alarm activation or a persistent anti-theft light.
- ✔ Intermittent no-start conditions where the engine cranks but won’t fire up.
- ✔ Wipers or radio behaving erratically.
- ✔ False warnings appearing on the instrument cluster, such as ‘Service 4WD’ or airbag lights.
- ✔ Rapid battery drain when the vehicle is parked.
The Plug-and-Play Solution: Programmed to Your VIN
Forget expensive dealership visits and programming fees. We take the hassle out of the repair process. When you order, simply provide us with your vehicle’s 17-digit VIN. Our technicians will then program this GM Body Control Module with the latest factory software updates specific to your exact vehicle configuration. This ensures that when the part arrives, it’s a true plug-and-play installation. You can restore your vehicle’s electronic systems right in your own driveway.
Important Post-Installation Information
While this module is programmed for a straightforward installation, some GM vehicles may require additional steps after the new BCM is connected. Please be aware of the following potential procedures:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a compatible professional scan tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On certain models, a brake pedal position sensor relearn may be necessary to ensure correct brake light operation and to prevent issues with the traction control system.

Frequently Asked Questions
What exactly does the Body Control Module do?
The BCM is a computer that manages many of your vehicle’s non-engine related functions. This includes power windows, power locks, interior and exterior lighting, the anti-theft system, wipers, and various other comfort and convenience features.
Do I need to get this BCM programmed by a dealer?
No. This is the biggest benefit of our service. We program the module to your vehicle’s specific VIN before we ship it to you. This means it’s ready for installation right out of the box, saving you time and the high cost of dealership programming.
How do I provide my VIN?
After you complete your purchase, you will receive instructions on how to send us your 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we receive this information, as the programming is essential for the part to function correctly.
What if my airbag light is on after I install the new BCM?
This can happen on some models. It means the new BCM needs to be electronically introduced to the airbag system (SDM). A procedure called ‘Setup SDM Primary Key in BCM’ will need to be performed by a qualified technician with a professional-grade diagnostic tool to clear the light.
Is there a core charge?
No, there is no core charge for this part. You can keep your original module without needing to send it back to us.
