Is Your GM Truck or Van Experiencing Electrical Gremlins?
If you’re dealing with erratic power windows, flickering lights, a malfunctioning security system, or other strange electrical issues in your Chevy Silverado, Express, GMC Sierra, or Savana, a failing Body Control Module (BCM) is the most likely culprit. The BCM acts as the central computer for your vehicle’s body electronics, and when it fails, it can cause a wide range of frustrating and unpredictable problems. Don’t let a faulty module keep your vehicle off the road. This is your direct, reliable solution.
From the Diagnostic Bay
We had a 2005 Chevy Silverado 2500 in the shop that was driving the owner crazy. The dome lights and cargo light would stay on intermittently, draining the battery overnight. He had replaced the battery twice and checked all the door jamb switches. After connecting our scan tool, we saw multiple communication loss codes pointing to the BCM. We installed a VIN-programmed GM Body Control Module, and the problem was solved instantly. It’s a classic case of how a single faulty computer can create a phantom electrical drain that’s nearly impossible to trace with wiring diagrams alone.
Common Symptoms of a Failing BCM
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ Interior or exterior lights staying on, flickering, or not turning on.
- ✔ The horn honking randomly or not working when pressed.
- ✔ Vehicle security system engaging unexpectedly or preventing the engine from starting.
- ✔ Inaccurate readings on the instrument cluster gauges.
- ✔ “Service Electrical System” or similar warnings on the dash.
- ✔ No communication with the BCM when using a diagnostic scan tool.
The Plug-and-Play Solution for Your GM Body Control Module
Replacing a BCM typically requires a trip to the dealership for expensive programming. We eliminate that hassle. Simply provide us with your vehicle’s VIN during checkout, and we will program the module with the latest GM software updates specific to your truck or van. It arrives at your door ready for installation, saving you time and money. This is a direct replacement for multiple part numbers, ensuring a perfect fit and restored functionality.
Installation & Post-Install Notes
Physical installation is straightforward for most DIY mechanics. The BCM is typically located under the steering column on trucks or in the center dash area on vans. While our VIN programming handles the critical setup, some vehicles may require a simple relearn procedure after installation.
- Airbag System Sync: If your 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: On some models, a brake pedal position sensor recalibration may be needed to ensure correct brake light operation.
Always consult a factory service manual or a qualified technician for vehicle-specific instructions.

Frequently Asked Questions
Do I need to program this BCM?
No. We handle all the programming for you before we ship the part. Just provide your vehicle’s VIN at checkout, and it will arrive ready to install.
What does the Body Control Module do?
The BCM is a computer that manages your vehicle’s non-engine related electronic systems. This includes power windows, locks, interior and exterior lighting, the security system, wipers, and more.
Where is the BCM located on my vehicle?
On 2003-2007 GM trucks like the Silverado and Sierra, the BCM is typically found under the driver’s side dashboard, near the steering column. On Express and Savana vans, it’s usually located behind the center dash panel.
What if my airbag light turns on after I install this?
If the airbag light illuminates, it means the new BCM needs to be synced with the airbag’s computer (SDM). This requires a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure.
Is there a core charge?
No, there is no core charge for this part. You can keep your old module.
