Restore Your Vehicle’s Electrical Systems and Drive with Confidence
Are you experiencing frustrating and unpredictable electrical issues in your GM vehicle? Flickering lights, malfunctioning power windows and locks, a security system that acts up, or strange warning messages on your dash are all 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 make driving a stressful experience. This Programmed GM Body Control Module 25826125 is the direct, reliable solution to restore your vehicle to its proper working order.
Common Symptoms & Your Solution
A faulty BCM can be difficult to diagnose, often presenting as a cluster of unrelated problems. If you’re dealing with any of the following, this module is likely the fix you need:
- Interior or exterior lights that don’t work, stay on, or flicker randomly.
- Power windows, door locks, or mirrors behaving erratically or not responding.
- The security system or keyless entry failing to work correctly.
- Warning lights (like the airbag light) illuminating without a clear cause.
- Diagnostic Trouble Codes (DTCs) related to communication errors (U-codes) or specific body functions.

Expert Insight: Why VIN Programming is Non-Negotiable
As a technician with over two decades of experience, I can’t stress this enough: a BCM is not a simple ‘plug-and-play’ part unless it’s programmed first. Your vehicle’s computersโthe Engine Control Module (ECM), Transmission Control Module (TCM), and BCMโall speak a unique digital language based on your VIN. Installing an unprogrammed module is like dropping a foreign-language speaker into a critical conversation; it leads to communication errors, non-functional features, and even no-start conditions. Our service of pre-programming this Programmed GM Body Control Module 25826125 handles this complex digital handshake for you, transforming a difficult repair into a simple component swap.
Frequently Asked Questions
Do I need to take this BCM to the dealer after installation?
No. The main benefit of our service is that we program the module to your vehicle’s VIN before we ship it. This eliminates the need for any additional programming by a dealer or mechanic, saving you significant time and money.
How do I provide my VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). You can typically add it as a note during checkout or reply to your order confirmation email. We cannot ship your part until we have your VIN to perform the programming.
What does the Body Control Module (BCM) actually do?
The BCM is a computer that acts as the central hub for your vehicle’s body electronics. It controls non-engine related functions like power windows, power locks, interior and exterior lighting, the security system, wipers, and more. When it fails, these systems can become unreliable.
What if my airbag light is on after installing the new BCM?
In some vehicles, the BCM and the airbag system (SDM) require a security sync. If the airbag light comes on, a procedure called ‘Setup SDM Primary Key in BCM’ will need to be performed with a professional-grade scan tool. This is a simple procedure for most repair shops.
Is this part difficult to install?
The BCM is typically located under the dashboard on the driver’s side. For most models, it’s a matter of disconnecting the battery, removing a few trim panels, and swapping the electrical connectors. While many DIY-ers can perform the swap, we always recommend consulting a service manual or a qualified technician if you are not comfortable with the process.
