Is your GM truck or van suffering from bizarre electrical problems?
If you’re dealing with flickering lights, malfunctioning power windows and locks, or a persistent security light, a failing Body Control Module (BCM) is the most likely culprit. The BCM acts as the central command center for your vehicle’s body electronics, and when it fails, it can cause a wide range of frustrating and unpredictable issues. Don’t let electrical gremlins keep your vehicle off the road. This direct-fit replacement BCM is your reliable, straightforward solution.
From the Diagnostic Bay
We had a 2005 Express 2500 work van come in with a classic BCM failure symptom: a dead battery every morning. The driver swore he was turning everything off. After a parasitic draw test, we traced the issue to the BCM, which wasn’t allowing the vehicle’s systems to go to ‘sleep’ after shutdown. It was constantly drawing power, draining the battery overnight. Swapping in a pre-programmed BCM like this one solved the problem immediately. The van was back in service the next day, saving the owner from lost work and a costly dealer diagnosis.
Common Symptoms of a Failing BCM
- ✔ Power windows, door locks, or mirrors operate intermittently or not at all.
- ✔ Interior or exterior lights flicker, stay on, or won’t turn on.
- ✔ The vehicle’s security system acts up, or the security light stays illuminated on the dash.
- ✔ The horn honks randomly or doesn’t work when pressed.
- ✔ Windshield wipers behave erratically or won’t park in the correct position.
- ✔ The radio or climate controls are non-responsive.
- ✔ You see a “Service Vehicle Soon” message on the instrument cluster.

Post-Installation Information
While our programming handles the majority of the setup, some vehicles may require a simple relearn procedure after installation. These can typically be performed with a high-end scan tool.
- Airbag System Sync: If the airbag warning light is on after installation, a technician will need to perform the “Setup SDM Primary Key in BCM” procedure to sync the modules.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be needed to ensure correct brake light and traction control operation.
There is no core charge for this part. You can keep your old module.
Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine related electronic functions, such as power windows, locks, lights, wipers, security system, and interior accessories.
Is this BCM truly plug-and-play?
Yes, for most vehicles. We program it to your VIN so it’s ready to install without needing a dealer visit for programming. In some cases, minor relearn procedures for systems like the airbag or brake sensor may be required, as noted in the description.
How do I provide my VIN?
After you complete your purchase, we will contact you for your vehicle’s 17-digit VIN. We cannot program and ship the module without it, so please provide it promptly to avoid delays.
What happens if my airbag light is on after I install the BCM?
This indicates the new BCM needs to be synced with the airbag’s Sensing and Diagnostic Module (SDM). A qualified technician with a professional scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Do I need to send my old BCM back?
No, there is no core charge on this part. You can keep your original module.
Will this BCM fit my Silverado or Sierra pickup?
Yes, this BCM fits a wide range of 2003-2007 GM trucks and vans. Please check the fitment list and verify that your original part number is listed to ensure compatibility.
