Are you battling frustrating electrical issues in your GM vehicle? Flickering lights, malfunctioning power windows, a haywire security system, or accessories that have a mind of their own 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 cascade of perplexing problems. This pre-programmed GM Body Control Module is the definitive solution to restore your vehicle’s functionality and your peace of mind.
Forget expensive dealership visits and the hassle of post-installation programming. We take care of the hard part for you. Simply provide your vehicle’s VIN during checkout, and our experts will program the module with the latest GM software specific to your car, truck, or SUV. This ensures a seamless installation process, getting you back on the road faster. This module is a direct replacement for a wide range of original equipment part numbers, making it a versatile and reliable fix.
Expert Pro Tip: Before installing your new BCM, take a moment to inspect the area around your old module. BCM failure is often caused by water intrusion from a leaky windshield seal, cowl drain, or sunroof drain. Correcting any leaks before installation will protect your new module and prevent a repeat failure down the road.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights
- ✔ Power windows, locks, or mirrors not working correctly
- ✔ Vehicle security system faults or false alarms
- ✔ Horn honking unexpectedly or not working at all
- ✔ Intermittent starting problems or no-start conditions
- ✔ Warning lights appearing on the dashboard without cause
- ✔ Wipers operating incorrectly or not turning off

Post-Installation Information
In most cases, this module is a plug-and-play installation. However, depending on your specific vehicle, a couple of simple relearn procedures may be required:
- Airbag System Sync: If the airbag warning 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: Some models may require a brake pedal position sensor recalibration to ensure proper function of the brake lights and traction control system.
Always consult a factory service manual or a qualified technician if you are unsure about any installation steps.
Frequently Asked Questions
What does the Body Control Module (BCM) do?
The BCM is a computer in your vehicle that controls and monitors a wide range of electronic accessories not related to the engine, such as power windows, locks, lights, wipers, security system, and more.
How do I know if this BCM will fit my vehicle?
Please review the detailed fitment list on this page. This module replaces many different part numbers. The most reliable way to ensure compatibility is to match your original part number to one in our cross-reference list. If you’re unsure, contact us with your VIN.
What does ‘programmed to my VIN’ mean?
It means we load the module with the specific software and settings for your vehicle’s exact configuration based on its Vehicle Identification Number (VIN). This eliminates the need for you to have it programmed at a dealership, saving you time and money.
Do I need special tools to install this?
For the physical installation, you will only need basic hand tools. However, as noted, some vehicles may require a professional diagnostic tool for post-installation procedures like the airbag system sync or brake pedal position relearn.
Why is my airbag light on after installing the new BCM?
This is a normal security measure. The new BCM needs to be electronically ‘introduced’ to the vehicle’s airbag system (SDM). A ‘Setup SDM Primary Key in BCM’ procedure must be performed with a compatible high-end scan tool to resolve this.
Is there a core charge?
No, there is no core charge for this part. You can keep your old module.
