Are you battling a storm of strange electrical issues in your GM vehicle? Flickering lights, malfunctioning power windows, a security system that has a mind of its own, or random warning messages on your dash 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 starts to fail, it can cause frustrating and unpredictable problems. This replacement BCM is the definitive solution to restore your vehicle’s functionality and your peace of mind.
This isn’t just a part in a box; it’s a complete, ready-to-install solution. Before we ship it, our experts program the module with the latest GM software, specifically matched to your vehicle’s VIN. This critical step ensures compatibility and bypasses the need for an expensive trip to the dealership for programming. You get a part that’s ready for installation right out of the box, saving you time and money.
Common Symptoms of a Failing GM BCM
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors not working correctly.
- ✔ The vehicle’s security system engaging randomly or preventing the car from starting.
- ✔ False warning lights on the instrument cluster (e.g., Airbag, ABS, Traction Control).
- ✔ Intermittent operation of the radio or climate controls.
- ✔ Communication loss with other vehicle modules, leading to multiple system failures.

Installation Notes
While this module is designed for a direct fit, some vehicles may require a simple post-installation procedure. If your airbag light is on after installation, a technician will need to perform an ‘SDM Key Relearn’ to sync the new BCM with the airbag system. Additionally, a ‘Brake Pedal Position Relearn’ might be necessary on some models to ensure proper brake light and traction control function. Always consult a service manual or a qualified technician for your specific vehicle.
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 various electronic accessories, such as power windows, locks, lights, wipers, and the security system. It acts as a hub for these functions.
How do I know if my BCM is the problem?
Common signs include multiple, unrelated electrical issues happening at once. For example, your power locks failing at the same time your dome light flickers. A professional scan tool can confirm communication faults with the BCM.
Is this part difficult to install?
The physical replacement is typically straightforward, often located under the dash. Since we pre-program the module to your VIN, you avoid the most complex part of the job. However, some vehicles may require post-install relearn procedures as noted in the description.
Do I need to send my old BCM back?
No. This part is sold with no core charge. You can keep your original module, which saves you the time and expense of return shipping.
What happens after I place my order?
After you purchase the BCM, you will need to provide us with your vehicle’s 17-digit VIN. We will then program the module with the latest GM software specific to your vehicle before we ship it to you.
