Are you battling frustrating electrical issues in your GM truck or van? Flickering lights, malfunctioning power accessories, or a persistent security warning 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 functionality and peace of mind.
This isn’t just a replacement part; it’s a fully prepared solution. We program the module to your vehicle’s specific VIN before shipping, loading it with the latest software updates from GM. This critical step ensures compatibility and proper communication with your vehicle’s other electronic systems, simplifying the installation process. Simply provide your VIN after purchase, and we’ll handle the complex programming for you.
We had a 2005 Sierra come in with the strangest combination of symptoms: the radio would turn off randomly, the passenger window wouldn’t roll down, and the horn would chirp every time the driver’s door was opened. The owner had already replaced the window switch and checked fuses to no avail. After a quick scan, we saw multiple communication errors pointing back to one source. A new, properly programmed BCM resolved every single issue. It’s amazing how many unrelated problems a faulty BCM can cause.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Instrument cluster gauges or warning lights behaving strangely.
- ✔ Headlights, taillights, or interior lights not working correctly.
- ✔ The security system light stays on, or the vehicle won’t start.
- ✔ The horn honks unexpectedly or doesn’t work at all.
- ✔ Wipers operate intermittently or won’t turn off.

Please note that while our programming handles the majority of the setup, some vehicles may require minor post-installation procedures.
Post-Installation Information
After installing your new BCM, certain systems may need to be re-synced. If your airbag warning light is illuminated, a professional scan tool will be needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. Additionally, some models may require a ‘Brake Pedal Position Relearn’ to ensure correct brake light and traction control operation. Always consult a factory service manual or a qualified technician for vehicle-specific instructions.
Frequently Asked Questions
What exactly does the Body Control Module do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine-related electronic functions. This includes power windows, door locks, the security system, lighting, wipers, and various other comfort and convenience features.
Is this part truly plug-and-play?
Because we program the module to your VIN, it is as close to plug-and-play as possible. It eliminates the need for dealership programming. However, as noted, some vehicles may require simple relearn procedures for systems like the airbag or brake pedal position sensor after installation.
How do I provide my VIN?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship your order until we receive this information, as it is essential for the programming process.
What if my airbag light is on after I install the BCM?
This is a known possibility. It means the new BCM needs to be electronically ‘introduced’ to your vehicle’s airbag system (SDM). A qualified mechanic with a professional-grade scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Do I need to send my old BCM back?
No. There is no core charge for this part. You can keep your original module.
Will this fit models other than the Silverado?
Yes, this BCM is compatible with a wide range of GM vehicles, including the Sierra, Savana, Express, and SSR from various years. Please refer to the detailed fitment list on this page to confirm it matches your exact make, model, and year.
