Are you experiencing frustrating and unpredictable electrical problems in your GMC Acadia, Chevrolet Traverse, or other compatible GM vehicle? A faulty Body Control Module (BCM) is often the culprit. The BCM acts as the central nervous system for your vehicle’s electronic accessories, managing everything from your power windows and locks to the interior lighting and security system. When it fails, it can cause a cascade of issues that are difficult to diagnose.
This replacement Body Control Module, corresponding to part number 25934762, is the definitive solution to restore your vehicle’s full functionality. We take the guesswork and hassle out of the repair by pre-programming the module to your vehicle’s specific VIN before it ships. This means no expensive trips to the dealership for programming—it arrives ready for installation.
From the Diagnostic Bay
We had a 2011 Acadia come in with a classic case of ‘automotive poltergeist.’ The owner reported random dash lights, interior dome lights staying on (draining the battery overnight), and power door locks that worked intermittently. They had already replaced the battery and checked the alternator, with no success. After hooking up our diagnostic tool, we saw multiple communication errors pointing to the BCM. By installing a VIN-programmed 2007-2012 Acadia BCM, we resolved all the electrical gremlins in one go, saving the customer from further diagnostic headaches and unnecessary parts replacement.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that won’t turn on or off.
- ✔ The security system malfunctioning or preventing the vehicle from starting.
- ✔ Dashboard warning lights appearing randomly (e.g., ABS, Airbag, Traction Control).
- ✔ Communication errors with diagnostic scan tools.
- ✔ Intermittent no-start or crank-no-start conditions.
- ✔ Radio or climate control systems behaving unpredictably.
The Plug-and-Play Solution: A Pre-Programmed 2007-2012 Acadia BCM
Don’t let a complex repair intimidate you. Our process is designed for simplicity and success. When you place your order, simply provide us with your vehicle’s 17-digit VIN. Our technicians will then flash the module with the latest, most stable software directly from GM, ensuring it is perfectly matched to your vehicle’s specific options and configuration. This critical step ensures all systems communicate correctly upon installation, making the process as close to plug-and-play as possible.
Installation Note: On the 2007-2012 GMC Acadia, the BCM is typically located on the left-hand (driver’s) side of the dash. While installation is straightforward, please be aware of potential post-installation procedures. In some cases, an ‘Airbag System Sync’ or ‘Brake Pedal Position Relearn’ may be required using a professional diagnostic tool if related warning lights appear. Always consult a factory service manual for your specific model.

Frequently Asked Questions
Do I need to have this BCM programmed by a dealer?
No. We program the module to your vehicle’s VIN before we ship it to you. It arrives ready to be installed, saving you time and money.
How do I provide my VIN?
You can enter your 17-digit VIN during the checkout process or send it to us with your order number after your purchase is complete.
What does the Body Control Module do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine related electronic functions, such as power windows, locks, lights, wipers, and the security system.
Where is the BCM located on my 2010 GMC Acadia?
For the 2007-2012 GMC Acadia, the BCM is typically found behind the dashboard on the driver’s side, near the steering column.
What if my airbag light turns on after I install the new BCM?
If the airbag light is on, it means the new BCM needs to be synchronized with the airbag system (SDM). This requires a ‘Setup SDM Primary Key in BCM’ procedure, which can be performed by a technician with a professional-grade scan tool.
Is there a core charge for my old part?
No, there is no core charge. You can keep your original module.
