Restore Full Electrical Control to Your SUV
Are you dealing with baffling electrical issues in your Chevy Suburban? One day the power windows work, the next they don’t. Maybe your A/C blower motor has a mind of its own, or you’re facing a frustrating no-start condition with the security light flashing. These aren’t just random glitches; they’re classic signs of a failing Body Control Module (BCM). This essential component is the central command for your vehicle’s body electronics. When it fails, it can cause a cascade of problems that are frustrating to diagnose and expensive to fix at a dealership.
This replacement BCM, part number 10367690, is the definitive solution. We pre-program it to your vehicle’s exact VIN, ensuring it works perfectly right out of the box. You get to skip the costly trip to the dealer for programming. This isn’t just a part; it’s a permanent fix that restores the reliability and functionality you depend on from your truck.
From the Diagnostic Bay: The Case of the Haunted Suburban
I had a 2005 Suburban 1500 roll into my bay last month with a list of complaints from the owner that sounded like the truck was possessed. The radio would switch off, the dome lights would flicker while driving, and the HVAC controls were completely dead. The owner had already replaced the battery and checked fuses. After hooking up my scan tool, I saw a handful of communication codes and a specific BCM internal failure code. In my 20+ years of experience, I’ve seen this exact pattern on hundreds of these GM trucks. The BCM’s internal circuit board had failed. We installed one of our VIN-programmed modules, and in less than 10 minutes, every single issue was resolved. The customer drove away with a reliable truck and saved hundreds compared to the dealership quote.
Is Your Suburban Showing These Telltale Signs?
- âś” Intermittent or non-functional power windows, door locks, or mirrors.
- âś” HVAC and climate control systems not responding or blower motor cutting out.
- âś” The security or anti-theft system preventing the engine from starting.
- âś” An active airbag warning light, often with a diagnostic trouble code (DTC) like B1001.
- âś” Erratic behavior from interior or exterior lights (flickering, staying on, or not turning on).
- âś” Communication errors with other modules on the vehicle’s network.
Your 5-Minute Installation Guide
Getting your truck back to 100% is easier than you think. This installation requires basic hand tools and can typically be completed in under 5 minutes. The BCM is located under the driver’s side dashboard, near the steering column.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the BCM: On your Suburban, it’s typically mounted to a bracket just above the driver’s left foot, to the left of the steering column.
- Disconnect and Remove: Carefully unplug the electrical connectors. They have release tabs that need to be pressed. Once disconnected, unclip or unbolt the old module and remove it.
- Install the New Module: Seat the new, pre-programmed BCM into the mounting bracket and securely plug in all the electrical connectors. You’ll hear a click as they lock into place.
- Reconnect and Test: Reconnect the negative battery terminal. Start the vehicle and test all functions: windows, locks, lights, wipers, and HVAC to confirm the repair.
Post-Installation Note: In some cases, an airbag light may appear. This requires a professional scan tool to perform the “Setup SDM Primary Key in BCM” procedure to sync the modules. This is a simple step for any qualified technician.

Frequently Asked Questions
Frequently Asked Questions
What exactly does a Body Control Module do?
The BCM acts as the central computer for your vehicle’s comfort and security features. It reads inputs from switches (like your window or lock buttons) and sensors, and then sends commands to operate everything from your interior lights and wipers to your HVAC system and security alarm.
Is this part really plug-and-play?
Yes. By programming the module to your vehicle’s VIN before shipping, we handle the critical software setup. This allows you to install it directly without needing a trip to the dealership for expensive programming, saving you time and money.
What if my airbag light is on after I install it?
This can happen occasionally. It means the new BCM needs to be electronically ‘introduced’ to the airbag’s Sensing and Diagnostic Module (SDM). A mechanic with a bi-directional scan tool can perform the ‘Setup SDM Primary Key’ procedure in a few minutes to clear the light.
Do I need to return my old BCM? Is there a core charge?
No. We do not require you to send back your original part. There is absolutely no core charge, making the process simpler and hassle-free for you.
Will this BCM fix my intermittent no-start problem?
If your no-start issue is caused by the factory anti-theft system (Passlock/Passkey) being triggered by a faulty BCM, then yes, this will resolve the problem. Our programming ensures the security data matches your vehicle.
What tools do I need for the installation?
Typically, you’ll only need a basic socket set or a nut driver to remove the old module and a flathead screwdriver to help release the connector tabs. No specialized tools are required for the physical installation.
