Is Your GM Truck or SUV Plagued by Bizarre Electrical Problems?
If you’re dealing with a frustrating array of issues like flickering lights, unresponsive power windows, a dead HVAC system, or random warning lights, the culprit is very likely a failing Body Control Module (BCM). This component is the central nervous system for your vehicle’s body electronics, and when it malfunctions, it can make your dependable truck or SUV feel unreliable. Get back in command with this OEM-quality, VIN-programmed Body Control Module, designed to restore full functionality and peace of mind to your vehicle.

Frequently Asked Questions
What does “VIN Programmed” mean for me?
It means we handle all the complex software setup for you before the part is shipped. You provide your vehicle’s 17-digit VIN during checkout, and we flash the module with the correct software and vehicle-specific settings. This makes the installation a simple plug-and-play process, saving you a trip to the dealership and their programming fees.
Is this difficult to install myself?
For most DIYers with basic tools, the installation is straightforward. The BCM is typically located under the driver’s side dashboard, near the steering column. It’s held in by a few clips or bolts and has several electrical connectors. The physical swap can often be done in under 15 minutes.
My airbag light is on. Will this fix it?
This module will resolve airbag light issues caused by a faulty BCM (like DTC B1001). However, after installation, some vehicles require an “SDM Key Relearn” or “Setup SDM Primary Key in BCM” procedure using a professional-grade scan tool to sync the new BCM with the airbag system and turn off the light. This is a simple procedure for any qualified mechanic.
Do I need to send my old BCM back?
No. There is no core charge for this part. You can keep, discard, or recycle your old module without any obligation.
Will this fit vehicles other than a 2013 GMC Sierra 2500?
Yes, absolutely. This 2013 GMC Sierra 2500 Body Control Module is compatible with a wide range of 2007-2013 GM trucks and SUVs, including the Chevrolet Silverado, Tahoe, Suburban, GMC Yukon, and Cadillac Escalade. Please verify your part number or check the compatibility list to ensure it’s the correct fit for your specific vehicle.
