Are you battling frustrating electrical issues in your GM truck or van? Flickering lights, malfunctioning power windows and locks, or a persistent security light are common signs of a failing Body Control Module (BCM). The BCM acts as 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. This replacement BCM is the definitive solution to restore your vehicle’s electronic systems to perfect working order.
This isn’t just a part; it’s a complete, ready-to-install solution. We pre-program this module with the latest GM software updates, specifically flashed to your vehicle’s unique VIN. This critical step ensures seamless integration and functionality, saving you from expensive dealership programming fees and complex setup procedures. Simply provide your VIN during checkout, and we handle the rest, shipping you a part that is ready for installation right out of the box.

A faulty BCM can make your reliable truck feel unpredictable. Replacing it with our pre-programmed unit is the most effective way to solve these issues permanently. This module is a direct replacement for a wide range of GM trucks and vans, ensuring a perfect fit and restored performance.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior or exterior lights that flicker, stay on, or don’t work at all.
- ✔ A persistent anti-theft or security system light, potentially causing no-start conditions.
- ✔ Wipers or radio turning on and off by themselves.
- ✔ False warning messages on the driver information center (DIC).
- ✔ Inaccurate gauge readings on the instrument cluster.
- ✔ Diagnostic trouble codes related to communication errors with other modules.
Simple Installation and Post-Install Notes
Installation is straightforward for a DIY mechanic or any professional technician. The BCM is typically located under the steering column in trucks or in the center dash area in vans. While our VIN programming makes this a near plug-and-play repair, some vehicles may require a simple follow-up procedure:
- Airbag System Sync: If the airbag (SRS) light is illuminated after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ function. This syncs the new BCM with your vehicle’s existing airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be required to ensure correct brake light operation and stability control function.

Frequently Asked Questions
What is a Body Control Module (BCM)?
The BCM is a computer in your vehicle that controls and monitors various electronic accessories, such as power windows, locks, lights, wipers, and the security system. It’s the brain for your truck’s body electronics.
Why is VIN programming so important?
VIN programming loads your vehicle’s specific software and options into the BCM. Without it, the module won’t communicate correctly with other systems, leading to features not working or even a no-start condition. Our service saves you a trip to the dealer for this essential step.
How do I provide my VIN?
After you complete your purchase, you will be prompted to provide your 17-digit Vehicle Identification Number (VIN). We cannot program and ship your BCM without it.
Do I need to return my old BCM?
No. There is no core charge for this part. You can keep your original module.
Is this part difficult to install?
The physical replacement is typically straightforward, involving unplugging connectors and removing a few bolts. It’s located under the driver’s side dash in most trucks. The key is that our pre-programming eliminates the most difficult part of the job.
What if my airbag light comes on after installation?
This is a known possibility. It simply means the new BCM needs to be electronically ‘introduced’ to the airbag module. This requires a ‘Setup SDM Primary Key’ procedure with a bi-directional scan tool, which any competent repair shop can perform.
