Is Your GM Truck Experiencing Strange Electrical Problems?
If your 2007-2011 GMC Sierra 3500, Chevrolet Silverado, or other compatible GM vehicle is plagued by frustrating electrical issues, a failing Body Control Module (BCM) is often the root cause. The BCM acts as the central command center for your truck’s body electronics, managing everything from your power windows and door locks to the HVAC system and security features. When it fails, it can create a cascade of problems that are difficult to diagnose and expensive to fix at a dealership.
This genuine OEM-quality BCM, part number 15284816 (interchangeable with 25844480 and others), is the definitive solution. We pre-program it to your vehicle’s specific VIN, ensuring it arrives ready for a straightforward, plug-and-play installation. This eliminates the need for a trip to the dealer for costly programming, getting you back on the road quickly and confidently.
Common Symptoms of a Failing BCM
- ✔ Unresponsive or erratic power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that won’t turn on or off.
- ✔ HVAC controls or blower motor not working correctly.
- ✔ Airbag warning light illuminated on the dash, often with DTC B1001.
- ✔ Vehicle security system malfunctions, causing no-start or stalling conditions.
- ✔ Intermittent warning messages or gauges on the instrument cluster.
- ✔ A variety of communication-related Diagnostic Trouble Codes (DTCs).

Frequently Asked Questions
What does ‘VIN Programmed’ mean for me?
It means the module arrives ready to install without any additional programming. We load your vehicle’s specific VIN and corresponding software onto the BCM before shipping, making it a true plug-and-play solution that saves you a trip to the dealership.
Do I need to return my old BCM?
No. There is no core charge for this part. You can keep your old module, which saves you the time and hassle of packaging and shipping it back.
My airbag light is on after installing the new BCM. What should I do?
This is a common security feature. You will need to have a qualified technician with a professional scan tool perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with your vehicle’s airbag system and will turn off the light.
Where is the BCM located on my truck?
The Body Control Module is typically located under the driver’s side of the dashboard, often near the steering column. It’s usually accessible after removing a lower dash panel.
Will this fix my intermittent stalling or misfire issues?
While a failing BCM can cause security system conflicts that lead to stalling, these symptoms can also be caused by other issues. A BCM replacement is a common fix for electrical-related stalling, but you should ensure your vehicle’s primary engine and fuel systems are in good working order.
