Are you battling frustrating electrical gremlins in your GM truck or van? Flickering lights, malfunctioning power windows, or a security system that acts on its own are common 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 confusing and intermittent problems. This replacement BCM is the definitive solution to restore full functionality and reliability to your vehicle.
We make the repair process simple. Unlike a trip to the dealership, which involves high labor costs and programming fees, this module arrives at your door fully programmed to your vehicle’s specific VIN. We install the latest GM software updates, ensuring optimal performance and compatibility. Just provide your VIN after purchase, and we’ll handle the complex programming for you. This means a more straightforward installation, getting you back on the road with confidence.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-working interior/exterior lights
- ✔ Power windows, locks, or mirrors operating intermittently
- ✔ Malfunctioning radio or climate controls
- ✔ Security system faults or a vehicle that won’t start
- ✔ False warning messages on the instrument cluster (e.g., ‘Service 4WD’)

Post-Installation Information
While this module is designed for a simple installation, some vehicles may require additional steps. If the airbag light is on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. Additionally, a ‘Brake Pedal Position Relearn’ may be necessary on certain models to ensure correct brake light and traction control operation. Always consult a factory service manual or a qualified technician for vehicle-specific guidance.
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 functions not related to the engine, such as power windows, locks, lights, security system, and climate controls.
Do I need to have this BCM programmed?
No. We program the BCM for you before shipping. Simply provide us with your vehicle’s 17-digit VIN during or after checkout, and it will arrive ready to install.
Is this part difficult to install?
For most DIYers with basic tools, the physical installation is straightforward. The BCM is typically located under the steering column in trucks or in the center dash area in vans. The main benefit of our product is that the difficult programming step is already done for you.
Will this fix my specific electrical problem?
This module corrects issues directly caused by a faulty BCM. If you are experiencing multiple, seemingly unrelated electrical problems like the ones listed in the symptoms, a failing BCM is the most likely cause.
What does ‘no core charge’ mean?
It means you do not have to send your old, faulty BCM back to us. This saves you time and the cost of return shipping.
