Are you battling bizarre electrical gremlins in your GM truck or van? Flickering lights, malfunctioning power windows, a security light that won’t turn off, or a battery that drains overnight 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 frustrating and seemingly unrelated issues. This VIN-programmed BCM is the definitive solution to restore your vehicle’s functionality and peace of mind.
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We flash the module with the latest GM software updates and program it specifically to your vehicle’s VIN before it ships. This means no expensive trips to the dealership for programming. For most vehicles, installation is a straightforward plug-and-play process, getting you back on the road quickly.
Common Symptoms of a Failing BCM
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ Interior or exterior lights flickering, staying on, or not turning on.
- ✔ The security or anti-theft system light is illuminated, preventing the vehicle from starting.
- ✔ The horn honking unexpectedly or not working.
- ✔ Inaccurate or erratic gauge readings on the instrument cluster.
- ✔ Unexplained parasitic battery drain that kills your battery.

Important Post-Installation Information
While this BCM is designed for a simple installation, some vehicles may require additional steps to ensure all systems communicate correctly. After installation, if you see an airbag warning light, a professional scan tool will be needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. Additionally, a ‘Brake Pedal Position Relearn’ may be necessary on some models to ensure proper brake light and traction control operation. These procedures are straightforward for any qualified technician.
Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM acts as the brain for your vehicle’s electronic accessories. It controls functions like power windows, door locks, interior and exterior lighting, the security system, and the instrument panel gauges.
Is this BCM difficult to install?
For most DIYers with basic tools, the installation is manageable. The BCM is typically located under the steering column or in the center dash area. Since we pre-program it to your VIN, the most complex part of the job is already done for you.
How do I provide my VIN for programming?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot ship your order until we receive your VIN, as the programming is essential for the part to function in your vehicle.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module.
What if my airbag light is on after I install the new BCM?
This can happen occasionally. It means the new BCM needs to be synced with the airbag system’s Sensing and Diagnostic Module (SDM). A qualified mechanic with a professional diagnostic tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Does this part fit Crew Cab models?
No, as noted in the fitment information, this specific BCM is for models excluding the Crew Cab configuration. Please verify your vehicle’s options before ordering.
