Restore Full Functionality to Your Vehicle’s Electronics
Are you battling strange and frustrating electrical issues in your GM vehicle? Flickering lights, malfunctioning power windows or locks, a security system that acts up, or warning lights that won’t go away are all classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can cause a wide range of perplexing problems. This replacement Body Control Module, part number 15299986, is the reliable, straightforward solution to get your car, truck, or SUV back in perfect working order.
Why Choose Our Programmed GM BCM?
The biggest hurdle in replacing a BCM is the need for expensive, dealer-specific programming. We eliminate that step entirely. When you purchase from us, you simply provide your vehicle’s VIN during checkout. Our technicians will then flash the module with the latest GM software specific to your vehicle’s configuration. This means the part arrives at your door ready for installation, saving you time, money, and the hassle of a dealership visit. This is not just a replacement part; it’s a complete, ready-to-install solution.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-working power windows, door locks, and mirrors.
- ✔ Erratic behavior from interior or exterior lights (flickering, staying on, or not turning on).
- ✔ Malfunctioning radio or infotainment system.
- ✔ Security system faults or anti-theft light illumination.
- ✔ Inaccurate gauge readings or dead gauges.
- ✔ Key fob not working correctly.
- ✔ Various warning lights on the dashboard, such as for the airbag or traction control system.
Installation and Post-Install Considerations
Physical installation is typically straightforward, as the BCM is often located under the dash. Once our pre-programmed module is installed, your vehicle should start and run. However, in some cases, additional synchronization procedures may be required. For example, if the airbag light is on, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. Similarly, a ‘Brake Pedal Position Relearn’ might be necessary. These are standard procedures for many modern vehicle repairs and can be performed by most qualified independent shops if needed.
Frequently Asked Questions
What exactly does a Body Control Module do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine-related functions. This includes power windows, locks, lights, wipers, the security system, and the climate control fans, among other things.
How do I provide my VIN for programming?
After you complete your purchase, we will contact you for your 17-digit Vehicle Identification Number (VIN). Our technicians use this to load the correct software and settings for your specific vehicle before we ship the part.
Is this a plug-and-play part?
For the most part, yes. Because we pre-program it, you avoid the most difficult step. The vehicle will start and run. However, as with any module replacement, some models may require minor relearn procedures for systems like the airbags or brake sensor, which may require a scan tool.
