Tired of Chasing Electrical Gremlins in Your GM Truck?
If your Silverado, Sierra, or Tahoe is acting possessed—with flickering lights, a dead A/C, or random warning messages—a failing Body Control Module (BCM) is the likely culprit. As the central command for your vehicle’s comfort and convenience features, a faulty BCM can cause a cascade of frustrating issues. This GM 15263497 BCM is the definitive, plug-and-play solution, arriving expertly programmed to your vehicle’s VIN to restore full functionality and get you back on the road with confidence.
Forget about expensive dealership visits and programming fees. We handle the complex part for you. By programming the module with the latest GM software updates before it ships, we ensure it communicates flawlessly with your truck’s other systems right out of the box. This is the same reliable fix I’ve used in my shop for years to solve the most baffling electrical problems on these otherwise dependable trucks and SUVs.
A Technician’s Notebook: The 2009 Silverado with a Mind of Its Own
A customer brought in a ’09 Silverado 1500 with a laundry list of complaints: the radio would cut out, the driver’s side window wouldn’t roll down, and the airbag light was on. He’d already replaced the battery and checked fuses. My first step, after verifying a solid ground connection (always check grounds first on these GMT900s!), was to hook up my professional scan tool. It lit up with a slew of communication codes and a specific DTC B1001 for the airbag system. This pattern almost always points to one component: a failing BCM. Instead of hours of wiring diagnostics, we installed a VIN-programmed module. Within 15 minutes, the truck was fully functional, and after a quick SDM key sync, the airbag light was gone. This is a classic case where the right part saves hours of labor and frustration.
Is Your Truck Showing These Symptoms?
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, it’s time to consider a replacement:
- ✔ Your A/C or heater controls work sporadically, or the blower fan cuts in and out without reason.
- ✔ The airbag warning light is illuminated, often with a DTC B1001 stored in the system.
- ✔ Power windows, door locks, or interior/exterior lights operate intermittently or not at all.
- ✔ The anti-theft or security system acts up, sometimes preventing the vehicle from starting.
- ✔ You’re experiencing strange grounding issues, stalling, or misfires that can’t be traced to the engine.
- ✔ Your scan tool shows multiple communication-related Diagnostic Trouble Codes (DTCs).

A Straightforward Guide to Installation
For most DIYers, this is a quick and simple job. The BCM is typically located under the driver’s side dashboard, near the steering column.
- Safety First: Disconnect the negative terminal from your vehicle’s battery and wait a few minutes for the systems to discharge.
- Locate the BCM: On most GM trucks and SUVs, it’s a black box with multiple large connectors, mounted to a bracket under the dash.
- Disconnect and Remove: Carefully unplug the electrical connectors. They have locking tabs that need to be depressed. Once unplugged, unbolt or unclip the old module from its mounting location.
- Install the New Module: Mount your new, pre-programmed BCM in the same location and securely plug in all the electrical connectors.
- Reconnect and Test: Reconnect the negative battery terminal. Start the vehicle and test all functions: windows, locks, lights, wipers, and HVAC to ensure everything is working correctly.
- Post-Installation Checks: In some cases, an ‘Airbag System Sync’ (Setup SDM Primary Key in BCM) is needed if the airbag light remains on. This requires a professional scan tool. A ‘Brake Pedal Position Relearn’ may also be necessary on certain models.
