Restore Full Electrical Function to Your GM Truck or SUV
Is your Chevrolet Silverado or GMC Sierra plagued by frustrating and unpredictable electrical problems? Do your power windows refuse to work, your door locks act on their own, or your HVAC system blow hot air on a summer day? These are classic signs of a failing Body Control Module (BCM), the central computer responsible for managing your vehicle’s body electronics. This genuine quality GM BCM, interchangeable with part number 15263363, is the definitive solution to restore your truck’s functionality and reliability. It arrives pre-programmed to your vehicle’s specific VIN, eliminating the need for expensive dealership visits and ensuring a seamless, plug-and-play installation.
Common Symptoms of a Failing BCM
A faulty BCM can manifest in numerous ways, often seeming like multiple unrelated issues. If you’re experiencing any of the following, your BCM is the likely culprit:
- ⚠ Intermittent or non-functional power windows, door locks, or interior/exterior lights.
- ⚠ HVAC controls not responding or the blower motor operating erratically.
- ⚠ The security system malfunctioning, causing no-start conditions or random alarm activation.
- ⚠ An illuminated airbag warning light, often accompanied by Diagnostic Trouble Code (DTC) B1001.
- ⚠ Unexplained battery drain while the vehicle is off.
- ⚠ Erratic wiper operation or failure to turn on/off.
From the Diagnostic Bay
We recently had a 2009 Silverado 2500 in the shop with a list of bizarre symptoms. The owner reported that his radio would sometimes stay on after he left the truck, his driver-side window worked only when it wanted to, and his remote start had stopped functioning. He had already replaced the battery and checked fuses with no luck. After connecting our scanner, we found multiple communication loss codes with various modules. This immediately pointed us to the network’s hub: the BCM. Instead of a costly diagnostic and programming session at the dealer, we installed one of our VIN-programmed modules. In under 10 minutes, every single one of his electrical gremlins was gone. It’s a perfect example of how a single component can cause widespread, confusing issues.

Installation & Post-Install Procedures
Installing your new Silverado 2500 Body Control Module is a quick process.

While the process is plug-and-play, some vehicles may require a simple relearn procedure.
Critical Warning
Critical Warning
Before installing your new BCM, inspect the main ground connections, especially the G218 ground pack located on the driver’s side A-pillar. Poor grounding is a common cause of BCM failure on these GM platforms. Failing to correct a bad ground can cause immediate damage to your new module, which is not covered under warranty.
Post-Installation Syncing: In some cases, particularly if your airbag light was on, you may need to perform a “Setup SDM Primary Key in BCM” procedure using a professional-grade scan tool. This re-establishes the security handshake between the new BCM and the airbag system. A brake pedal position relearn may also be required for proper brake light and traction control operation.
