Are you battling frustrating electrical problems in your GM truck or van? Issues like flickering lights, malfunctioning power windows and locks, or a security system that prevents your vehicle from starting are often traced back to a failing Body Control Module (BCM). The BCM acts as the central hub for your vehicle’s body electronics, and when it fails, it can cause a wide range of confusing symptoms. This replacement BCM, part number 15136224, is the definitive solution to restore full functionality and reliability to your vehicle.
We make the repair process simple. This isn’t just a part in a box; it’s a complete, ready-to-install solution. Upon purchase, simply provide us with your vehicle’s VIN. Our technicians will then program the module with the latest official GM software specific to your vehicle’s configuration. This ensures seamless integration and performance, eliminating the need for an expensive trip to the dealership for programming.
We had a 2005 Silverado 2500 come in on a tow truck. The owner was convinced the engine was shot because it would crank but never start, and the security light was flashing on the dash. He’d already replaced the battery and checked the fuel pump. After a quick scan, we saw communication errors with the BCM. Instead of a costly engine repair, the fix was a simple, pre-programmed BCM swap. Within 30 minutes of installation, the truck fired right up, and all the strange electrical gremlins were gone. It’s a perfect example of how this single component can mimic much more severe problems.
Common Symptoms of a Failing GM BCM
- ✔ Intermittent or non-working power windows, door locks, or interior lights.
- ✔ The security or anti-theft light stays on, preventing the engine from starting.
- ✔ Headlights or taillights acting erratically or not turning on/off correctly.
- ✔ The radio or instrument cluster loses power intermittently.
- ✔ False warning lights appearing on the dashboard.
- ✔ Inability to communicate with the module using a diagnostic scan tool.
Easy Installation for Your 2003-2007 Savana 2500 BCM
This module is designed for a straightforward installation. Once you receive your VIN-programmed BCM, you simply locate your old module (typically under the steering column or in the center dash area), disconnect the battery, swap the modules, and reconnect the battery. In most cases, the vehicle will start and run with all functions restored. However, depending on your specific model, a couple of simple relearn procedures may be necessary.
- Airbag System Sync: If your airbag warning light is on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system.
- 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 is a direct replacement for a wide range of part numbers, including: 15167329, 15194169, 15747545, 15136224, 15116065, 15198115, 15136876, and 10367689. It fits numerous GM trucks and vans from 2003-2007, such as the Chevrolet Silverado, Express, SSR, and the GMC Sierra and Savana. Please verify the fitment list to confirm compatibility with your exact model and options.
Frequently Asked Questions
Why do you need my VIN?
Your Vehicle Identification Number (VIN) allows us to program the BCM with the exact software and settings your vehicle had when it left the factory. This ensures all your specific options (like power windows, keyless entry, etc.) work correctly right out of the box.
Is this BCM difficult to install?
For most DIY mechanics, the physical installation is straightforward. It involves disconnecting the battery and swapping the module, which is usually located under the dashboard. The key is that our pre-programming service eliminates the most difficult step: the need for dealer-level software tools.
What does ‘No Core Charge’ mean?
It means you do not have to send your old, faulty BCM back to us. You can keep it, recycle it, or dispose of it as you see fit, with no extra fees or deposits required.
What if the airbag light comes on after I install it?
This is a known possibility. The new BCM needs to be electronically ‘introduced’ to the airbag’s computer (SDM). This is done via a ‘Setup SDM Primary Key in BCM’ procedure, which requires a professional-grade scan tool. Any local repair shop should be able to perform this quick procedure for you.
Will this fix my no-start problem?
If your no-start issue is caused by the factory anti-theft system (Passlock/VATS) being triggered by a faulty BCM, then yes, this VIN-programmed module will resolve that problem. A flashing security light is a strong indicator that the BCM is the culprit.
