Restore Full Electronic Functionality to Your GM Vehicle
Is your 2008-2012 Chevrolet Express 1500 or other compatible GM vehicle suffering from bizarre electrical problems? Flickering lights, malfunctioning power windows, or a security system that has a mind of its own are all common signs of a failing Body Control Module (BCM). The BCM acts as the central command center for your vehicle’s body electronics, and when it starts to fail, it can cause a cascade of frustrating and difficult-to-diagnose issues. This replacement Body Control Module, part number 15299986, is the definitive solution to restore your vehicle’s performance and reliability.
From the Diagnostic Bay
We had a 2011 Savana work van come into the shop with a complaint of an intermittent no-start and the radio turning on and off by itself. The owner had already replaced the battery and alternator, but the issues persisted. A scan showed multiple communication loss codes (U-codes) pointing to the BCM. After confirming power and ground to the module were good, we identified the internal BCM failure. Instead of a costly trip to the dealer, we installed one of our VIN-programmed modules. The van started reliably, all electronics functioned perfectly, and the customer was back on the road the same day, saving significant time and money.
Symptoms of a Failing Body Control Module
A faulty BCM can manifest in numerous ways, often mimicking other component failures. If you’re experiencing any of the following, your BCM is the likely culprit:
- ✔ Erratic power windows, door locks, or mirrors that work intermittently or not at all.
- ✔ Interior dome lights, headlights, or taillights staying on or not turning on.
- ✔ The security system engaging randomly, preventing the vehicle from starting (anti-theft light flashing).
- ✔ Dashboard gauges sweeping, flickering, or providing incorrect readings.
- ✔ Malfunctioning HVAC controls, with the fan or temperature settings not responding.
- ✔ Key fob not being recognized or having a very short range.
- ✔ Communication error codes stored in the vehicle’s computer system.
Why Our VIN-Programmed 2008-2012 Express 1500 BCM is the Superior Choice
Simply installing a used BCM from another vehicle won’t work. The module is programmed with a specific vehicle’s VIN and options. Our service eliminates the hassle and high cost of dealership programming. When you order from us, we take your vehicle’s VIN and flash this module with the latest, most stable software updates directly from GM. This ensures that the BCM is a true plug-and-play component, perfectly matched to your vehicle’s specific configuration. There is no core charge, so you can keep your original module.
Installation & Post-Install Procedures
On most Express and Savana vans, the BCM is located in the center dash area. While installation is straightforward for a knowledgeable technician, some post-install steps may be required to ensure all systems communicate correctly.
- Airbag System Sync: If the airbag warning light illuminates after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional scan tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: In some cases, a brake pedal position sensor recalibration may be needed to ensure proper function of the brake lights and traction control system.
Always consult a factory service manual or a qualified professional for vehicle-specific instructions.

Frequently Asked Questions
What exactly does the Body Control Module do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine related electronic systems. This includes power windows, locks, lights, security system, wipers, and interior climate controls. It’s the brain for passenger comfort and convenience features.
Is this BCM ready to install right out of the box?
Yes. Once we program it with your vehicle’s VIN, it is ready for installation. In some cases, minor post-installation procedures like an airbag sync or brake pedal relearn may be necessary, which require a professional diagnostic tool.
Where is the BCM located on my 2008-2012 Express 1500?
On the 2008-2012 Express and Savana vans, the Body Control Module is typically located behind the dashboard, in the center area, often accessible after removing some lower dash panels.
What happens if I forget to provide my VIN?
Providing your VIN is essential for the programming process. We cannot ship the module until we receive your VIN, as the part will not function correctly without being matched to your vehicle’s specific software and options.
Why is my airbag light on after installing the new BCM?
The new BCM needs to be electronically ‘introduced’ to the vehicle’s Sensing and Diagnostic Module (SDM), also known as the airbag module. This requires a ‘Setup SDM Primary Key in BCM’ procedure using a compatible high-end scan tool to sync the components and turn off the light.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module.
