Is your Chevrolet Express or GMC Savana Van plagued by frustrating electrical issues?
If you’re dealing with intermittent power windows, a malfunctioning HVAC system, flickering lights, or a security system that won’t cooperate, a failing Body Control Module (BCM) is the most common culprit. This essential component acts as the central nervous system for your van’s body electronics. When it fails, it can cause a cascade of confusing and seemingly unrelated problems. This VIN-programmed BCM, part number 15064149, is the definitive solution to restore full functionality and reliability to your 2004-2007 Express 2500 Van and other compatible GM vehicles.
From the Diagnostic Bay
We had a 2006 Express 2500 work van come into the shop with a complaint of the blower motor only working on high speed. The owner had already replaced the blower motor and the resistor, but the problem persisted. A quick scan revealed communication DTCs pointing to the BCM. Instead of chasing phantom wiring issues, we installed a VIN-programmed BCM. Not only did it fix the HVAC controls, but it also resolved an intermittent door lock issue the owner hadn’t even mentioned. It’s a perfect example of how a single faulty module can create multiple headaches.

This module arrives ready for a quick, straightforward installation, making it the ideal choice for both professional technicians and DIY mechanics.
Built to strict OEM standards, this BCM guarantees the same performance and longevity as the original factory part. It directly interchanges with a wide range of part numbers, including 15116066, 15136225, 15198116, and more, making it a versatile fix for many GM trucks and vans from the era.
Installation and Post-Install Notes
Installation is typically a 5-10 minute job. On Express and Savana vans, the BCM is located in the center dash area. Simply disconnect the battery, remove the old module, plug in the new one, and reconnect the battery. There is no core charge, so you can keep your old part.
In some cases, post-installation procedures may be needed:
- Airbag System Sync: If the airbag light remains on, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional scan tool.
- Brake Pedal Position Relearn: Some models may require this recalibration for proper brake light and traction control function.
Restore your van’s electrical integrity and get back on the road with confidence. This programmed 2004-2007 Express BCM is your reliable, hassle-free fix.
Frequently Asked Questions
What does a Body Control Module do on a 2005 Chevy Express?
The BCM is a computer that manages and controls many of your van’s non-engine related electronic functions. This includes the power windows, door locks, interior and exterior lighting, security system, wipers, and the HVAC climate control system.
Is this BCM difficult to install?
No, the physical installation is very simple and usually takes less than 10 minutes. It’s typically located in the center dash and involves unplugging the old module and plugging in the new one. Since we pre-program it to your VIN, no further computer setup is required for most functions.
Do I need to go to the dealership after installing this part?
No. Our VIN programming service eliminates the need for a trip to the dealer for programming. It’s designed to be a plug-and-play solution, saving you time and money.
What if my airbag light is on after I install the new BCM?
If the airbag light is on, it means the new BCM needs to be synced with the vehicle’s airbag system (SDM). This requires a ‘Setup SDM Primary Key in BCM’ procedure, which can be done by a repair shop with an advanced diagnostic scan tool.
How do I know this is the correct part for my van?
This BCM fits 2004-2007 Chevrolet Express and GMC Savana vans with the commercial tradesman package (opt PRP). It also interchanges with many other part numbers. You can verify fitment by matching your old part number to the list on our page or by contacting us with your VIN.
