Common Symptoms & Your Solution
A failing BCM is the central nervous system of your van’s electronics, and its failure can cause a wide range of frustrating issues. If you’re experiencing any of the following, this module is the reliable fix you need:
- Erratic or non-working interior and exterior lights
- Power windows, door locks, or mirrors failing intermittently
- HVAC and climate control blower motor issues
- An illuminated airbag warning light, often with DTC B1001
- Security system faults leading to a no-start condition
- A cluster of seemingly unrelated diagnostic trouble codes (DTCs)
Replacing your faulty unit with our pre-programmed 2004-2007 Express 3500 BCM 15194170 restores these critical systems to perfect working order without an expensive trip to the dealership.

From the Mechanic’s Bench: Why VIN Programming is Non-Negotiable
On these GMT800 platform vehicles, the BCM is the traffic cop for dozens of electronic systems. It constantly communicates with other modules like the Powertrain Control Module (PCM) and the Airbag/Sensing Diagnostic Module (SDM). Simply swapping a BCM from another vehicle won’t workโthe VIN mismatch will cause communication errors, trigger the security system, and can even disable the vehicle. Our VIN programming service writes your van’s unique identity directly to the module, ensuring it integrates seamlessly, just like the original part from the factory. This is the key to a successful, permanent repair.
Frequently Asked Questions
Do I need to have this BCM programmed by a dealer?
No. We pre-program the module to your vehicle’s VIN before shipping. This makes the installation plug-and-play, saving you the time and expense of a dealership visit.
Where is the BCM located on my Express van?
On the 2004-2007 Express and Savana vans, the Body Control Module is typically located in the center of the dashboard, often accessible by removing a lower dash panel.
My airbag light is on. Will this fix it?
A faulty BCM can cause the airbag light to illuminate. After installing this new module, the light should go off. If it remains on, a simple “Setup SDM Primary Key in BCM” procedure may need to be performed with a professional scan tool to re-sync the modules.
Is this a difficult part to install myself?
For someone with basic mechanical skills, the installation is straightforward and usually takes less than 30 minutes. The primary steps involve disconnecting the battery, accessing the module, swapping the electrical connectors, and securing the new unit. Our plug-and-play 2004-2007 Express 3500 BCM 15194170 makes the electronic side of the job simple.
What if this doesn’t solve my problem?
While this BCM resolves the most common electrical issues for these vans, we always recommend proper diagnostics. If the new module doesn’t fix your issue, the problem may lie in the wiring, a sensor, or another component. This part is covered by a one-year warranty for your protection.
