Is your 2008-2012 Express 3500 Van experiencing bizarre electrical problems? Issues like flickering interior lights, malfunctioning power windows and locks, or a security system that acts up on its own are often signs of a failing Body Control Module (BCM). The BCM is the central computer for your vehicle’s body electronics, and when it fails, it can cause a wide range of frustrating and difficult-to-diagnose symptoms. This replacement BCM is the definitive solution to restore your van’s full functionality.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior or exterior lights staying on, flickering, or not working at all.
- ✔ The security system or alarm engaging randomly or preventing the vehicle from starting.
- ✔ Inconsistent or non-working dashboard gauges and warning lights.
- ✔ Problems with the heating and A/C blower motor controls.
- ✔ A persistent parasitic battery drain leading to a dead battery.

Post-Installation Procedures
While this module is designed for a direct fit, some vehicle systems may require a ‘handshake’ with the new BCM after installation. Be aware of the following potential procedures:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is necessary. This requires a professional-grade scan tool to sync the systems and clear the light.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be needed to ensure correct brake light operation and traction control function.

Frequently Asked Questions
What does the Body Control Module (BCM) do?
The BCM acts as the central computer for your vehicle’s body electronics. It controls non-engine related functions like power windows, locks, lights, wipers, security system, and climate controls.
Do I need to get this module programmed by a dealer?
No. We program the module to your vehicle’s specific VIN before we ship it. This saves you a costly trip to the dealership and makes the installation process much simpler.
Where is the BCM located on a 2008-2012 Express 3500 Van?
On the Express and Savana vans, the BCM is typically located in the center dash area. Always consult a service manual for the exact location and removal procedure for your specific vehicle.
What if my airbag light turns on after I install the new BCM?
This is a known possibility. The new BCM needs to be synced with the airbag’s Supplemental Inflatable Restraint (SIR) module. This requires a ‘Setup SDM Primary Key’ procedure using a professional scan tool.
Is there a core charge for this part?
No, there is no core charge. You can keep your old module without needing to send it back to us.
