Get Your Truck Back to Work Without the Hassle
Are you dealing with bizarre electrical issues in your Silverado, Sierra, or Express van? Flickering lights, power windows with a mind of their own, or a security system that won’t cooperate can bring your workday to a halt. These aren’t just annoyances; they’re symptoms of a failing Body Control Module (BCM), the central command for your truck’s body electronics. This isn’t a part you can ignore. We offer the definitive, straightforward solution: a replacement BCM, part number 15198115, that arrives at your door fully programmed to your vehicle’s specific VIN.
Common Symptoms & Your Solution
A faulty BCM can cause a cascade of frustrating problems. If you’re experiencing any of the following, it’s a strong sign that your module needs replacement:

- Power windows, door locks, or mirrors not responding correctly
- The security or anti-theft system preventing the truck from starting
- Inaccurate readings on the instrument cluster

Expert Insight: The BCM’s Critical Role
As a technician who’s spent years working on these GMT800-platform trucks, I can tell you the BCM is the unsung hero of the electrical system. It’s the traffic cop that directs signals for everything you interact with inside the cab. When it fails, the truck becomes unreliable. In the past, replacement meant towing it to a dealer, paying for the part, and then paying a hefty labor charge for programming. Our pre-programmed solution changes the game. It puts the power back in your hands, letting you complete a professional-level repair in your own garage or shop, drastically reducing downtime and cost. Getting a Programmed 15198115 Body Control Module is the smartest way to solve this common issue.
Frequently Asked Questions
What exactly does the Body Control Module do?
The BCM is a computer that supervises and controls many of your vehicle’s non-engine-related functions. This includes power windows, power mirrors, power door locks, the anti-theft system, interior and exterior lighting, and wipers. When it fails, any of these systems can become unreliable.
How do I know for sure that my BCM is the problem?
While the symptoms listed above are strong indicators, a definitive diagnosis often requires a professional scan tool that can check for communication codes (U-codes) from the BCM. However, if you are experiencing multiple, unrelated electrical issues simultaneously, the BCM is the most likely culprit.
Is this part difficult to install?
For most of the trucks and pickups listed, the BCM is located under the steering column and is accessible after removing a few trim panels. It’s typically held in with a few bolts or clips and has several electrical connectors. For someone with basic mechanical skills, it’s a very manageable job. On the vans, it’s located in the center dash. Since our Programmed 15198115 Body Control Module is pre-flashed, the hardest part of the job (the programming) is already done for you.
What happens after I place my order?
After you complete your purchase, you will need to provide us with your 17-digit Vehicle Identification Number (VIN). We cannot ship the module until we have this information. Once we receive your VIN, we will program the module with the correct software and ship it to you.
What if my airbag light comes on after installation?
In some cases, the new BCM may need to be synced with the airbag system’s computer (SDM). If the airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure will need to be performed by a qualified technician with a professional-grade scan tool.
Do I need to send my old BCM back to you?
No. This product has no core charge. You can keep, recycle, or dispose of your original module as you see fit.
