Are you battling frustrating electrical problems in your GM truck or van? Flickering lights, malfunctioning power windows, a security system that acts up, or random warning messages on your dash are common 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 confusing and intermittent issues. This module is the definitive solution to restore your vehicle’s electronic systems to perfect working order.
This is a direct-fit replacement Body Control Module for a wide range of 2003-2007 GM vehicles, including the Silverado, Sierra, Express, and Savana.

Is Your GM Vehicle Showing These Symptoms?
- ✔ Erratic or non-functional interior/exterior lights
- ✔ Power windows, locks, or mirrors not working correctly

Installing Your GM BCM Replacement
This module is engineered for a straightforward installation, typically located under the steering column or in the center dash area depending on your model. Once installed, it’s designed to be a plug-and-play solution. However, due to the complexity of modern vehicle systems, a couple of additional steps may be required. If your airbag light illuminates after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. Additionally, some models may require a ‘Brake Pedal Position Relearn’ to ensure proper brake light and traction control function. With no core charge, you can keep your old part, making the process even more convenient. This GM BCM Replacement is the most reliable and efficient way to solve your vehicle’s electrical issues.

Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that manages and controls various electronic accessories, such as power windows, locks, lights, wipers, and the security system. It acts as a central hub for these functions.
Why do you need my VIN?
We require your Vehicle Identification Number (VIN) to program the BCM with the correct software and vehicle-specific options from GM. This ensures the module works seamlessly with your truck or van right out of the box, saving you a trip to the dealer.
Is this part difficult to install?
For most DIY mechanics, the physical installation is straightforward. The BCM is usually accessible under the dashboard. The main benefit of our service is the pre-programming, which handles the most complex part of the job for you.
Will I need any special tools after installation?
In some cases, yes. If the airbag light comes on, a professional-grade scan tool is required to sync the airbag system (SDM) to the new BCM. A brake pedal position relearn may also be necessary. These are standard procedures for this type of repair.
Is there a core charge for this part?
No, there is no core charge. You are not required to send your old BCM back to us, which simplifies the process and saves you money on shipping.
