Is Your Truck’s Electrical System Acting Up?
If you’re dealing with baffling electrical problems in your 2007-2011 Chevrolet Silverado or GMC Sierra, the Body Control Module (BCM) is the most likely culprit. As the central command center for your vehicle’s body electronics, a failing BCM can cause a cascade of frustrating issues, from flickering lights and non-responsive windows to a dead HVAC system or even security-related starting problems. This isn’t just an inconvenience; it can compromise your vehicle’s safety and functionality. This genuine GM Body Control Module, interchangeable with part number 15263363, is the definitive solution to restore order and reliability to your truck’s essential systems.
From the Diagnostic Bay
We had a 2009 Silverado 1500 come into the shop with a laundry list of bizarre symptoms. The radio would turn on by itself, the driver’s side power window worked intermittently, and the dome light would stay on for minutes after the door was closed. The owner had already replaced the battery and checked fuses with no luck. After connecting our scanner, we saw multiple communication error codes pointing toward the BCM. Instead of a complex and costly wiring chase, we installed a VIN-programmed BCM. In under 10 minutes, every single one of the ghost-in-the-machine issues was gone. It’s a perfect example of how one component can create widespread, confusing problems, and how the right part makes for a simple, effective repair.
Is Your Silverado Suffering from These BCM Failure Symptoms?
- ✔️ Power windows, door locks, or mirrors work sporadically or not at all.
- ✔️ Interior or exterior lights (headlights, taillights, dome lights) behave erratically.
- ✔️ The HVAC system is unresponsive, or the blower motor won’t turn on.
- ✔️ Your vehicle’s security system malfunctions, causing false alarms or preventing the engine from starting.
- ✔️ The airbag warning light is illuminated, often with a DTC like B1001.
- ✔️ Wipers operate at the wrong speed or won’t turn off.
- ✔️ Diagnostic trouble codes (DTCs) related to body functions are present.

Installation and Post-Install Considerations
Installation is straightforward for the average DIY mechanic. The BCM is typically located under the driver’s side dashboard, near the steering column. The physical swap takes only a few minutes. However, please be aware of potential post-installation procedures:
- Airbag System Sync: If the airbag warning light remains on after installation, a procedure called “Setup SDM Primary Key in BCM” must be performed. This requires a professional-grade scan tool and syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor relearn to ensure proper brake light and traction control operation.

Frequently Asked Questions
What does the Body Control Module do on my Silverado?
The BCM acts as the central computer for your truck’s body electronics. It controls non-engine related functions like power windows, door locks, interior/exterior lights, the security system, wipers, and the HVAC climate control system.
Is this module ready to install out of the box?
Yes. We program the module to your vehicle’s specific VIN before shipping. This ensures it communicates correctly with your truck’s other systems for a true plug-and-play installation, with no dealership programming required.
What if my airbag light is on after I install the new BCM?
This is a common security feature. You will need a professional scan tool to perform the “Setup SDM Primary Key in BCM” function. This syncs the new BCM to your vehicle’s airbag module and will turn off the light.
Where is the BCM located on a 2007-2011 Silverado?
The BCM is typically found under the driver’s side dashboard, attached to or near the steering column. It’s usually accessible after removing the lower dash panel.
Do I need to send my old part back?
No, there is no core charge on this Body Control Module. You can keep or dispose of your old part without any additional fees or hassle.
