Restore Full Electronic Function to Your GM Truck or SUV
Are you battling bizarre electrical issues in your Chevrolet Silverado, GMC Sierra, or Tahoe? Flickering lights, a dead HVAC system, or power windows with a mind of their own are classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can cause a cascade of frustrating and difficult-to-diagnose problems. This genuine OEM-quality GM Body Control Module, interchangeable with part number 15263363, is the definitive solution. It arrives pre-programmed to your vehicle’s specific VIN, eliminating the need for expensive dealership programming and ensuring a simple, plug-and-play installation.
From the Diagnostic Bay
We recently had a 2011 GMC Yukon Denali come into the shop with a strange combination of symptoms: the security light was on, the driver’s side power window wouldn’t work, and the A/C blower was intermittent. The owner had already replaced the window switch and blower motor resistor with no success. A quick scan revealed multiple communication loss codes with the BCM. Instead of hours of chasing wires, we installed a VIN-programmed module like this one. In under 15 minutes, every single issue was resolved. These modules are the nerve center of the vehicle, and replacing a faulty one is often the quickest path to a complete repair.
Symptoms of a Failing Body Control Module
A faulty BCM can manifest in numerous ways. If you’re experiencing any of the following, your BCM is the likely culprit:
- ⚠ Non-functional or erratic power windows, door locks, or interior/exterior lights.
- ⚠ HVAC system failure, including an inoperative blower motor or inability to change temperature settings.
- ⚠ Illuminated airbag warning light, often accompanied by Diagnostic Trouble Code (DTC) B1001.
- ⚠ Security system malfunctions, causing no-start conditions or random alarm activation.
- ⚠ Intermittent stalling, misfires, or other seemingly unrelated engine performance issues due to grounding problems within the BCM.
- ⚠ A dashboard that looks like a Christmas tree, with multiple warning lights on at once.

After installation, if your airbag warning light is illuminated, you must perform the “Setup SDM Primary Key in BCM” procedure. This requires a professional-grade diagnostic scan tool. It is not an optional step; the airbag system will remain inactive until this synchronization is completed. Additionally, a Brake Pedal Position Relearn may be necessary on some models.
