Restore Full Functionality to Your GM Vehicle’s Electronics
Are you battling bizarre and frustrating electrical problems in your GM car, truck, or SUV? Issues like flickering lights, malfunctioning power windows and locks, a faulty security system, or random warning lights on your dash are often symptoms of 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 unpredictable problems. This replacement module, part number 10382479, is the definitive solution to restore your vehicle’s proper operation.
From the Diagnostic Bay
We once had a customer with a Chevy Impala who had spent hundreds of dollars replacing individual window switches and door lock actuators, convinced they were all failing at once. The issues were intermittent and maddening. After bringing it to our shop, a quick scan revealed communication faults with the BCM. We installed a VIN-programmed module, and instantly, every single electronic feature started working perfectly. It’s a classic case where the ‘brain’ was the problem, not the individual components.
Is Your GM Vehicle Experiencing These Issues?
- ✔ Power windows, mirrors, or door locks working intermittently or not at all.
- ✔ Interior or exterior lights flickering, staying on, or not turning on.
- ✔ The security system acting up, preventing the car from starting (Security light on).
- ✔ The horn honking randomly or the panic alarm going off unexpectedly.
- ✔ Inaccurate gauge readings or warning lights that have no apparent cause.
- ✔ Problems with the radio, climate control, or other interior accessories.
Why Choose Our Programmed GM Body Control Module?
Forget expensive dealership visits and the hassle of post-installation programming. We offer a simple, direct solution. When you purchase this BCM, you provide us with your vehicle’s VIN. Our technicians will then program the module with the latest GM software specific to your exact vehicle build. This means the part arrives at your door ready for installation. In most cases, it’s a true plug-and-play fix that gets you back on the road without needing specialized scan tools for setup.
Installation and Post-Install Considerations
Installation is typically straightforward, involving locating the old BCM (often under the dash), disconnecting the battery, swapping the modules, and reconnecting everything. While our programming handles the majority of the setup, some vehicles may require simple relearn procedures after installation:
- Airbag System Sync: If your airbag 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: On some models, a brake pedal position sensor relearn may be needed to ensure correct brake light and traction control operation.
This single module is a direct replacement for a wide array of part numbers, making it a versatile solution for many GM vehicles produced between 2006 and 2013. Please verify your part number or vehicle in the fitment list to ensure compatibility.
Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that manages and controls electronic accessories like power windows, locks, lights, wipers, security systems, and more. It’s the command center for non-engine related electronics.
How do I provide my VIN for programming?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship your order until we receive this information, as the programming is essential for the part to function.
Is this part difficult to install?
For someone with basic mechanical skills, the physical installation is generally not difficult. It involves removing a few dash panels to access the module. The main benefit of our service is that the complex software programming is already done for you.
Will this fix my ‘Service Security System’ message?
A failing BCM is a very common cause of security system faults and no-start conditions in GM vehicles. While other issues can cause this, replacing a faulty BCM often resolves these security-related problems.
Is there a core charge for my old part?
No, there is no core charge. You can keep your original module without needing to send it back to us.
