Restore Full Electrical Function to Your GM Vehicle
Are you battling bizarre electrical gremlins in your 2008-2012 Chevy Express or GMC Savana van? Issues like flickering lights, malfunctioning power windows and locks, or a security system that prevents the engine from starting are common signs of a failing Body Control Module (BCM). The BCM acts as the central hub for your vehicle’s body electronics, and when it fails, it can cause a cascade of frustrating and seemingly unrelated problems. This replacement Body Control Module is the definitive solution to restore your vehicle’s systems to perfect working order.
From the Diagnostic Bay
We had a 2011 Express 2500 work van come in that was a complete mystery to the owner. The dome lights would stay on, the driver’s side power lock wouldn’t work, and intermittently, the van wouldn’t start, just showing a security light on the dash. After checking all the fuses and wiring, we connected our diagnostic tool and found multiple communication loss codes with the BCM. Instead of a complex wiring nightmare, the fix was a straightforward replacement. We installed a VIN-programmed BCM, and all the strange electrical issues vanished instantly. The van was back in service the same day.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Erratic behavior from interior or exterior lights (flickering, staying on, or not turning on).
- ✔ The security or anti-theft light is illuminated, often causing a no-start condition.
- ✔ Dashboard gauges behaving erratically or not working at all.
- ✔ Horn, radio, or climate control systems working intermittently.
- ✔ Diagnostic trouble codes (DTCs) related to communication loss with the BCM.
Solving Issues with Your Express 1500 Body Control Module
Don’t let a faulty module keep your vehicle off the road. This unit is a direct-fit replacement, designed to solve the issues caused by a defective original part. We take the guesswork and hassle out of the repair process. Simply provide us with your vehicle’s VIN during checkout, and our technicians will program the module with the latest GM software specific to your van’s configuration. This ensures a seamless installation process without the need for an expensive trip to the dealership for programming.
Plug & Play Installation & Post-Install Steps
Installation is straightforward for a DIY mechanic or any professional technician. Once installed, your vehicle will be back to normal. However, in some cases, additional steps may be needed:
- 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 relearn to ensure proper brake light and traction control operation.

Frequently Asked Questions
What is a Body Control Module (BCM)?
The BCM is a computer in your vehicle that controls and monitors many of its electronic accessories, such as power windows, locks, lights, security system, and wipers. It’s the command center for passenger comfort and convenience features.
Do I need to program this module?
No. We handle the programming for you before shipment. Just provide your vehicle’s 17-digit VIN when you order, and the module will arrive ready for installation with the latest software from GM.
Is this part difficult to install?
For most models, including the Express and Savana vans, the BCM is located in the center dash area and is accessible with basic hand tools. It’s a plug-and-play electrical component. However, always consult a service manual for your specific vehicle’s location and replacement procedure.
Will this fix my ‘Service Theft System’ light?
A faulty BCM is a very common cause of a ‘Service Theft System’ or security light being illuminated, which can prevent the vehicle from starting. Replacing it with our pre-programmed module is a highly effective solution for this specific problem.
What if my airbag light comes on after installation?
This is a known possibility. It means the new BCM needs to be electronically introduced to the airbag system’s computer (SDM). A procedure called ‘Setup SDM Primary Key in BCM’ must be performed with a professional-grade diagnostic tool to resolve this.
Is there a core charge for my old part?
No, there is no core charge. You can keep your original module without needing to send it back to us.
