Restore Full Functionality to Your Vehicle’s Electronics
Are you battling bizarre and frustrating electrical problems in your GM vehicle? Intermittent power windows, flickering lights, a security system that acts on its own, or a car that refuses to start can all point to a single culprit: a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it malfunctions, it can cause a wide range of confusing issues. This replacement GM Body Control Module is the definitive solution to restore your vehicle’s proper operation and your peace of mind.
Is Your GM Body Control Module Failing?
A faulty BCM can manifest in numerous ways, often seeming unrelated. If you’re experiencing any of the following, it’s a strong indicator that your BCM needs replacement:
- ✔ Power windows, door locks, or mirrors operating erratically or not at all.
- ✔ Interior or exterior lights flickering, staying on, or not turning on.
- ✔ The security system or keyless entry malfunctioning.
- ✔ Warning lights on the dashboard (like Airbag or ABS) illuminating without a clear cause.
- ✔ The vehicle failing to start, even with a good battery and starter.
- ✔ Radio or climate control systems not working correctly.
- ✔ Inability for a scan tool to communicate with the module.

Important Installation Notes
While this module is designed for a straightforward installation, some vehicles may require additional steps after the new BCM is connected. Please be aware of the following potential procedures:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a procedure called ‘Setup SDM Primary Key in BCM’ must be performed with a professional-grade scan tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be necessary to ensure the brake lights and traction control system function as intended.
Always consult a factory service manual or a qualified technician for vehicle-specific instructions.

Frequently Asked Questions
What is a Body Control Module (BCM)?
The BCM is a computer in your vehicle that controls and monitors a wide variety of electronic accessories not related to the engine, such as power windows, locks, lights, wipers, security systems, and more.
Do I need to take this part to a dealer for programming?
No. We handle the programming for you before we ship the part. Simply provide your vehicle’s VIN at checkout, and we will flash the module with the correct software for your specific vehicle, saving you time and money.
How do I find my original BCM part number?
The part number is printed on a sticker on the case of your original BCM. The location varies by model but is often found under the dashboard on the driver’s side, in the center console, or behind the glove box.
What if my airbag light comes on after I install the new BCM?
This can happen on certain models. It means the new BCM needs to be electronically ‘introduced’ to the airbag system. A qualified mechanic with a high-level scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Is this a difficult part to replace myself?
For someone with moderate DIY mechanical skills, the physical replacement is typically straightforward. It involves locating the old module, disconnecting the battery, swapping the electrical connectors, and mounting the new one. However, always be prepared for potential post-installation procedures as mentioned.
