Restore Control and Reliability to Your Chevrolet Traverse
Are you dealing with baffling electrical issues in your 2009-2012 Chevrolet Traverse? Flickering dashboard lights, power windows with a mind of their own, or a security system that randomly prevents your SUV from starting can be incredibly frustrating. These aren’t just annoyances; they’re signs that your vehicle’s central nerve center, the Body Control Module (BCM), is failing. This isn’t a problem you have to live with. We offer the definitive, hassle-free solution to get your family’s vehicle back to being the reliable transport you depend on.
Common Symptoms & Your Solution
A failing BCM can turn your daily drive into a stressful guessing game. If you’re experiencing any of the following, it’s a strong indicator that your BCM needs replacement:
- Unresponsive power windows, door locks, or mirrors
- Interior or exterior lights that stay on, flicker, or don’t work at all
- The security or anti-theft light is illuminated on the dash
- Erratic behavior from the radio or climate control system
- The vehicle won’t start, and you hear a rapid clicking sound
- False warning messages appearing on the driver information center
Our Programmed 2009-2012 Traverse BCM is the perfect fix for these issues. We take a genuine OEM module and flash it with the latest GM-certified software, specifically matched to your vehicle’s unique VIN. This eliminates the need for an expensive trip to the dealership for programming, saving you time and money.

Expert Insight: Why VIN Programming is Non-Negotiable
Many people are tempted to buy a used BCM from a salvage yard to save money, but this is almost always a mistake. A BCM is not a simple part; it’s coded with the specific options and security information of its original vehicle. Installing a used, un-programmed module in your Traverse will, at best, cause more electrical chaos and, at worst, prevent the vehicle from starting entirely. Our VIN programming service isn’t just a convenienceโit’s the essential step that makes this repair possible outside of a dealership, ensuring all your vehicle’s features function exactly as the factory intended.
Frequently Asked Questions
What exactly does the Body Control Module 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, door locks, interior and exterior lighting, the security system, and the wipers. When it fails, these systems can become erratic or stop working completely.
Do I need to do any programming or flashing myself?
No. The main benefit of our service is that we do all the programming for you. After you purchase, you’ll provide us with your vehicle’s VIN, and we will flash the module before it ships. This makes the installation process much simpler.
How do I send you my VIN?
After you complete your purchase, you can send us a message with your 17-digit Vehicle Identification Number (VIN). You can find your VIN on your vehicle’s registration, insurance card, or on a plate on the driver’s side of the dashboard visible through the windshield.
What if my airbag light is on after I install the new BCM?
In some cases, the new BCM may need to be synced with the airbag system’s computer (SDM). If the airbag light appears after installation, a technician will need to perform a ‘Setup SDM Primary Key in BCM’ procedure with a professional scan tool. This is a simple sync procedure that resolves the light.
Is this part compatible with other GM vehicles besides the Traverse?
Yes, absolutely. This BCM, part number 20935349, is a compatible replacement for dozens of GM models from the late 2000s and early 2010s, including the GMC Acadia, Buick Enclave, Chevy Impala, Cadillac DTS, and many more. Please check the detailed fitment list on this page to confirm compatibility with your specific vehicle.
