Are you battling frustrating electrical problems in your GM vehicle? Issues like erratic power windows, flickering dash lights, or a security system that won’t cooperate are often signs of a failing Body Control Module (BCM). The BCM acts as the central command center for your vehicle’s body electronics, and when it malfunctions, it can cause a cascade of confusing and seemingly unrelated symptoms. This replacement Body Control Module is the reliable, straightforward solution to restore your vehicle’s full functionality.
This isn’t just a part; it’s a complete, ready-to-install solution. We pre-program this module to your vehicle’s specific VIN before it ships, loading it with the latest GM software updates. This critical step eliminates the need for an expensive trip to the dealership for programming, saving you time and money. Simply provide your VIN at checkout, and we’ll handle the rest, ensuring a seamless installation process.
Common Symptoms of a Failing BCM:
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ Instrument cluster lights flickering, dimming, or failing to illuminate.
- ✔ False security system alarms or a “Service Theft System” message.
- ✔ Interior dome lights or exterior lights staying on or not turning on at all.
- ✔ HVAC (Air Conditioning and Heat) controls not responding.
- ✔ Intermittent no-start conditions where the engine cranks but won’t fire.
- ✔ Communication loss with other vehicle modules.

Post-Installation Information
While our BCMs are designed for straightforward installation, some vehicles may require additional steps after the part is connected. If your airbag warning light appears, a simple ‘Setup SDM Primary Key in BCM’ procedure with a professional scan tool will be needed to sync the systems. Additionally, a ‘Brake Pedal Position Relearn’ may be necessary on some models to ensure proper brake light and traction control function. These are standard procedures that any qualified technician can perform.
Frequently Asked Questions
What does a Body Control Module do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine related functions, such as power windows, locks, lights, security system, wipers, and climate controls. It’s the brain behind your car’s creature comforts.
Is this BCM ready to install out of the box?
Yes! This module is pre-programmed to your vehicle’s VIN before we ship it. This means it’s ready for installation without needing a trip to the dealer for programming, though some minor relearn procedures may be required post-installation.
How do I find my original BCM part number?
Your BCM is typically located under the driver’s side dashboard, near the steering column. The part number is printed on a sticker on the module’s housing. Matching this number to our compatible list ensures you get the right part.
What if my airbag light is on after I install the new BCM?
This is a common security measure. A technician will need to use a professional diagnostic tool to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the airbag system with the new BCM and turn off the light.
Do I need to send my old part back?
No, there is no core charge for this part. You can keep your original module.
