Tired of Unpredictable Electrical Problems in Your Chevy Express?
If you’re dealing with a 2004-2007 Chevrolet Express 1500 Van that seems to have a mind of its own—with flickering lights, a dead HVAC blower, or power locks that work one minute and not the next—you’ve likely met the common failure point: the Body Control Module (BCM). As the central command for your van’s body electronics, a failing BCM can cause a cascade of frustrating issues that are often difficult to diagnose. This isn’t just an inconvenience; it can affect your work, security, and safety. This replacement Body Control Module, part number 15064149, is the definitive, hassle-free solution.
We take the guesswork and high dealership costs out of the equation. Each module is expertly programmed to your van’s specific Vehicle Identification Number (VIN) before it ships. This means no expensive trips to the dealer for programming. It arrives ready for a true plug-and-play installation, restoring full function to your vehicle’s essential systems and getting your reliable workhorse back on the road.
A Technician’s Notebook
I recently had a 2006 Express 2500 work van in my bay with a classic BCM failure story. The owner, a plumber, complained his dome lights wouldn’t turn off, draining the battery overnight, and his power door locks were completely dead. He’d already replaced the battery and checked fuses. After a quick scan, I saw a handful of communication codes. Instead of chasing electrical gremlins for hours, we went straight for the BCM. A quick swap with a pre-programmed unit like this one solved every single issue in under 10 minutes. It’s a prime example of how a single component failure can mimic multiple unrelated problems, and why a quality, programmed 2004-2007 Express 1500 BCM is often the fastest and most reliable fix.
Is Your Express Van Showing These Signs?
- ✔️ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔️ HVAC system problems, such as a blower motor that won’t turn on or erratic temperature control.
- ✔️ An active airbag warning light, often accompanied by Diagnostic Trouble Code (DTC) B1001.
- ✔️ Security system malfunctions, including the vehicle not starting due to a perceived theft attempt (Passlock issues).
- ✔️ Exterior or interior lights behaving erratically—staying on, not turning on, or flickering.
- ✔️ A dashboard lit up with various warning lights and communication-related DTCs.
Plug-and-Play Installation: Get Your Van Working in Minutes
- ✔ Safety First: Before you begin, disconnect the negative terminal from your vehicle’s battery to prevent electrical shorts and help reset the system.
- ✔ Locate the BCM: In the Express and Savana vans, the BCM is typically found in the center of the dashboard, often behind a lower access panel. It’s a black plastic box with several large electrical connectors.
- ✔ Swap the Module: Carefully unplug the wiring harnesses from the old BCM. They have release tabs that need to be pressed. Once disconnected, remove the old module from its mounting bracket and install the new one.
- ✔ Reconnect and Power Up: Securely plug the wiring harnesses into your new, pre-programmed BCM. Reconnect the negative battery terminal.
- ✔ Final Checks: Start the van and test all functions: lights, wipers, locks, windows, and HVAC. In most cases, the repair is complete. For specific issues like a lingering airbag light, see our post-installation notes below.

Frequently Asked Questions
Frequently Asked Questions
Do I need to have this BCM programmed by a dealer?
No. We program the module to your vehicle’s VIN before shipping. It arrives ready to install, saving you time and the high cost of dealership programming.
Is there a core charge for my old part?
Absolutely not. There is no core charge on this BCM. You can keep your old part without any hassle or need to return it.
What if my airbag light stays on after installation?
This can happen occasionally. It means the new BCM needs to be synced with the airbag’s Sensing and Diagnostic Module (SDM). A professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ procedure to clear the light.
How difficult is the installation for a DIYer?
This is a great DIY-friendly repair. The module is typically easy to access in the center dash, and the swap itself takes only a few minutes with basic tools. Our installation guide above walks you through it.
Will this fix my van’s no-start problem?
If your no-start issue is caused by the security system (Passlock) being triggered by a faulty BCM, then yes, this new programmed module will resolve the problem.
What is the warranty on this 2004-2007 Express 1500 BCM?
This part is backed by our one-year warranty, giving you peace of mind and confidence in your repair.
