Are you battling frustrating electrical problems in your Silverado, Sierra, Express, or Savana? Issues like flickering lights, unresponsive power windows and locks, or a security system that acts on its own are common signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics. When it fails, it can cause a cascade of confusing and unpredictable problems. This replacement BCM is the definitive solution, arriving pre-programmed to your vehicle’s specific VIN for a straightforward installation.

Important Post-Installation Steps
While this module is designed for a simple installation, some vehicles may require additional steps to ensure all systems communicate correctly:
- 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.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be necessary to ensure proper brake light and traction control operation.
Always consult a factory service manual or a qualified technician for vehicle-specific procedures.
Frequently Asked Questions
What exactly does the Body Control Module do?
The BCM acts as the brain for your vehicle’s body electronics. It controls functions not related to the engine, such as power windows, locks, lights, wipers, the security system, and the horn.
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 the module until we receive and program it with your VIN.
Is this BCM difficult to install?
On most Silverado and Sierra pickups, the BCM is located under the steering column and is accessible by removing the lower dash panel. On Express and Savana vans, it’s typically behind the center dash. Installation involves disconnecting the battery and swapping the modules.
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 comes on after I install this?
This is a known possibility. It means the new BCM needs to be electronically introduced to the airbag system. A technician with a professional-grade scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve it.
Does this fit Crew Cab models?
No, as noted in the fitment data, this specific BCM is for models excluding Crew Cab configurations. Please verify your truck’s cab style before ordering.
