Is Your Chevy Express Van Plagued by Electrical Gremlins?
The Body Control Module (BCM) is the central command center for your 2004-2007 Chevrolet Express or GMC Savana van’s body electronics. When it begins to fail, it can cause a host of confusing and frustrating issues, from flickering lights and non-working power windows to intermittent HVAC operation and even no-start conditions. Don’t let a faulty BCM keep your workhorse off the road. This direct-fit, VIN-programmed Body Control Module, part number 10383536, is the definitive solution to restore your van’s electronic systems to perfect working order.
From the Diagnostic Bay
We had a 2006 Express 2500 work van come into the shop that was driving the owner crazy. One day the blower motor wouldn’t work, the next the power locks were acting up, and sometimes the security light would stay on, preventing it from starting. The owner had already replaced the battery and checked fuses. After hooking up our scanner, we saw multiple communication error codes pointing to the BCM. Instead of a complicated wiring chase, the fix was simple: we installed a VIN-programmed 2004-2007 Express BCM. In under 10 minutes, all the strange electrical issues were gone, and the van was back in service, making money for its owner.
Common Symptoms of BCM Failure
- ✔ Intermittent or non-functional power windows, door locks, or interior/exterior lights.
- ✔ HVAC blower motor or climate controls not working correctly.
- ✔ Airbag warning light illuminated on the dash, often with DTC B1001.
- ✔ Vehicle security system malfunctioning, leading to a no-start condition.
- ✔ Wipers operating erratically or not at all.
- ✔ A variety of seemingly unrelated diagnostic trouble codes (DTCs) stored in the system.

Installation Guide for Your 2004-2007 Express BCM
Installing your new BCM is a straightforward process. It is typically located in the center dash area. Always disconnect the vehicle’s battery before beginning the installation to prevent electrical damage and help reset system memory. After swapping the module, reconnect the battery. In most cases, the van will start and operate correctly immediately. However, some vehicles may require additional steps:
- Airbag System Sync: If the airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional scan tool.
- 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 does the BCM do on a 2004-2007 Chevy Express Van?
The Body Control Module acts as the main computer for your van’s non-engine related electronics. It controls functions like power windows, door locks, the security system, interior and exterior lighting, wipers, and the HVAC system.
Do I need to program this BCM at the dealership?
No. We pre-program the module to your vehicle’s VIN before shipping. This makes it a true plug-and-play solution, saving you a trip to the dealer and additional programming fees.
Is this part difficult to install?
Installation is generally simple for someone with basic mechanical skills and can often be completed in under 15 minutes. The BCM is usually located in the center dash. Disconnecting the battery first is the most critical step.
What if my airbag light comes on after I install it?
This can happen occasionally. It means the new BCM needs to be electronically ‘introduced’ to the airbag system’s computer (SDM). This requires a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure.
Is there a core charge for this part?
No, there is no core charge. You are not required to send your old, faulty module back to us.
