Restore Full Electrical Function to Your GM Truck or SUV
Is your Silverado, Sierra, or Tahoe plagued by frustrating electrical issues? Flickering lights, unresponsive power windows, a dead HVAC system, or a persistent airbag light are common signs of a failing Body Control Module (BCM). The BCM acts as the central nervous system for your vehicle’s body electronics, and when it malfunctions, it can create a cascade of seemingly unrelated problems. This genuine quality GM Body Control Module, interchangeable with part number 15263497, is the definitive solution, arriving pre-programmed to your vehicle’s VIN for a true plug-and-play installation.
From the Diagnostic Bay
We recently had a 2013 Silverado 2500 in the shop with a classic case of BCM failure. The owner had already replaced the blower motor resistor and the master window switch, trying to chase down intermittent HVAC and power window problems. After a quick scan, we found multiple communication codes pointing back to one source. By installing a VIN-programmed BCM, we solved all the issues in under 10 minutes, saving the customer from further costly and incorrect parts replacements. Don’t guess—diagnose the root cause.
Common Symptoms of a Failing BCM
- ✔ Unresponsive or erratic power windows, door locks, or interior/exterior lights.
- ✔ HVAC system failures, including an inoperative blower fan or inability to change temperature.
- ✔ Illuminated airbag warning light, often with DTC B1001 (Setup SDM Primary Key in BCM).
- ✔ Malfunctioning security system, leading to no-start conditions or random alarm activation.
- ✔ Wipers operating incorrectly or not at all.
- ✔ A variety of communication-related Diagnostic Trouble Codes (DTCs).
Solving Problems with a Programmed 2013 Silverado BCM
Replacing the BCM is often the only way to resolve these deep-seated electrical faults. Our service simplifies the process entirely. We take your vehicle’s VIN and program the module before it ships, loading it with the latest GM software updates. This eliminates the need for an expensive trip to the dealership for programming. The module arrives ready to install, syncing perfectly with your truck’s existing components. It’s a direct-fit replacement for a wide range of GM trucks and SUVs from 2007-2013, including the Silverado, Sierra, Suburban, Tahoe, Yukon, and Escalade.
Installation and Post-Install Considerations
The BCM is typically located under the driver’s side dashboard, near the steering column, making the physical swap quick and easy. In most cases, the process is plug-and-play. However, be aware of two potential post-installation procedures:
- Airbag System Sync: If the airbag warning light remains on after installation, a technician will need to perform the “Setup SDM Primary Key in BCM” procedure using a professional scan tool. This is a simple sync process that resolves the B1001 code.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration to ensure proper brake light and traction control operation.
This module comes with no core charge, allowing you to keep your old part without the hassle of returning it. Restore your vehicle’s reliability and functionality with this precision-programmed BCM.
Frequently Asked Questions
Do I need to program this 2013 Silverado BCM?
No. This Body Control Module comes pre-programmed to your vehicle’s specific VIN. Simply provide your VIN at checkout, and the module will arrive ready for plug-and-play installation.
Where is the BCM located on my truck?
The BCM is typically found under the driver’s side dashboard, attached to or near the steering column. Installation usually takes only a few minutes with basic tools.
What if my airbag light is on after I install the new BCM?
If the airbag light is on, it means the new BCM needs to be synced with the vehicle’s Sensing and Diagnostic Module (SDM). A technician with an advanced scan tool can perform the “Setup SDM Primary Key in BCM” function to turn off the light.
Is this BCM compatible with other part numbers?
Yes, this module is a direct replacement for numerous part numbers, including 25844480, 25835966, 15263363, 15878753, 20939137, 22860591, and more.
Will this fix my intermittent power windows and door locks?
Yes, a faulty BCM is one of the most common causes of erratic power window and door lock operation. Replacing it with this programmed unit is a reliable way to fix those issues.
Is there a core charge for this part?
No, there is no core charge. You can keep your original module without needing to send it back.
