Is Your GM Truck or SUV Plagued by Electrical Gremlins?
If you’re dealing with flickering lights, unresponsive power windows, a malfunctioning security system, or a climate control system with a mind of its own, the culprit is likely a failing Body Control Module (BCM). The BCM acts as the central command center for your vehicle’s body electronics, coordinating everything from your interior lights and door locks to your windshield wipers and HVAC blower. When it fails, it can cause a cascade of frustrating and seemingly unrelated issues in your Chevrolet Silverado, GMC Sierra, Tahoe, Yukon, or Cadillac Escalade.

We pre-program it to your vehicle’s specific VIN, ensuring it arrives ready for a true plug-and-play installation. No expensive trips to the dealership for programming are required. Restore full electrical functionality and reliability to your vehicle with a module designed to meet or exceed original equipment standards.

Installation & Post-Install Notes
The BCM is typically located under the driver’s side dashboard, near the steering column, making for a straightforward replacement that often takes less than 15 minutes. However, please be aware of potential post-installation procedures. If the airbag warning light is illuminated after installation, a professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ function to sync the systems. Additionally, some models may require a ‘Brake Pedal Position Relearn’ to ensure proper brake light and traction control operation. Always consult a factory service manual for your specific vehicle.
Frequently Asked Questions
What does this Body Control Module do?
The BCM is a computer that manages and controls your vehicle’s non-engine related electronic functions. This includes power windows, door locks, interior/exterior lighting, the security system, climate controls, and windshield wipers.
Is this module ready to install right out of the box?
Yes. We program the module to your vehicle’s VIN before shipping. This makes it a true plug-and-play part, requiring no additional programming from a dealership.
Why is my airbag light still on after installing the new BCM?
This is a common security feature. The new BCM needs to be electronically ‘introduced’ to the airbag’s Sensing and Diagnostic Module (SDM). This requires a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure, which syncs the modules and turns off the light.
Do I have to send my old part back?
No. There is no core charge or fee associated with this part. You can keep or dispose of your old module at your convenience.
How can I be sure this fits my vehicle?
This module fits a wide range of 2007-2013 GM trucks and SUVs, including the Silverado, Sierra, Tahoe, Suburban, Yukon, and Escalade. Please verify your part number against the interchange list or use our website’s fitment checker to confirm compatibility.
