Restore Full Functionality to Your 2004-2007 Savana 1500 Van with a Programmed BCM
If you’re dealing with baffling electrical issues in your GMC Savana or Chevrolet Express van, you’re not alone. As the central command for your vehicle’s body electronics, a failing Body Control Module (BCM) can cause a cascade of problems that are frustrating for any owner, especially if you rely on your van for work. This OEM-quality BCM, part number 15064149, is the definitive solution, arriving pre-programmed to your van’s specific Vehicle Identification Number (VIN) for a true plug-and-play repair.
Over my 20+ years in automotive diagnostics, I’ve seen countless GM vans come into the shop with symptoms that seem unrelated—the radio works one minute and not the next, the power locks have a mind of their own, or the HVAC blower motor quits without warning. More often than not, the culprit is a faulty BCM. A replacement from the dealership involves high costs, a tow, and waiting for them to perform the programming. Our module eliminates that hassle. By programming it with the latest GM software before it ships, we ensure it communicates perfectly with your van’s other systems right out of the box, restoring the reliable performance you depend on.
Case Study: A Tricky Diagnosis
A local contractor brought in his ’06 Savana 2500, a workhorse with over 200,000 miles. His complaint was a classic “ghost in the machine” scenario: intermittent no-start, flickering interior lights, and the security light would stay on, preventing him from getting to job sites. He’d already replaced the battery and checked the grounds. After hooking up my scanner, I found several communication loss codes with the BCM. Instead of spending hours tracing wires for a potential short, we started with the most likely cause. We installed a VIN-programmed BCM, and within 10 minutes, every single issue was resolved. He was back on the road the same afternoon, saving him from losing a full day of work. This is the power of a reliable, correctly programmed module.
Is Your Savana Van Showing These Electrical Faults?
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, this module is your likely solution. This is especially true if you have a 2004-2007 Savana 1500 BCM that has never been replaced.
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ HVAC controls not working, or the blower motor only works on certain speeds or not at all.
- ✔ The security system light stays on, causing a no-start or crank-no-start condition.
- ✔ Headlights, taillights, or interior dome lights acting erratically.
- ✔ The airbag warning light is illuminated, often with a diagnostic trouble code (DTC) like B1001.
- ✔ False warnings on the instrument cluster or gauges behaving strangely.
A Straightforward Guide to Installation
For the handy van owner or professional mechanic, installing this BCM is a quick process. In most Savana and Express vans, the module is located behind a panel in the center of the dash, near the floor. No complex tools are needed.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work. This prevents shorts and helps reset the vehicle’s systems.
- Locate the BCM: On the 2004-2007 Savana/Express, find the BCM in the center dash area. You may need to remove a lower trim panel for access.
- Unplug and Unbolt: Carefully disconnect the electrical connectors. They have locking tabs, so be sure to press them before pulling. Then, remove the bolts or screws holding the old BCM in place.
- Install the New Module: Mount your new, pre-programmed BCM and securely reconnect all electrical harnesses. You’ll hear a click as they lock into place.
- Reconnect and Test: Reconnect the battery terminal. Turn the key to the ‘On’ position and test all functions: lights, locks, windows, wipers, and HVAC to confirm the repair.
Post-Installation Note: In some cases, an airbag light may remain on. This requires a professional scan tool to perform the “Setup SDM Primary Key in BCM” procedure to sync the modules. A brake pedal position relearn might also be necessary on certain models.

Frequently Asked Questions
Does this BCM need to be programmed by a dealer?
No. We pre-program the module to your vehicle’s VIN before shipping. It arrives ready for installation, with no extra programming required, saving you time and money.
Is this a difficult part for a DIYer to install?
Not at all. Installation typically takes less than 15 minutes with basic hand tools. The BCM is easily accessible in the center dash area of the Savana and Express vans.
What is a core charge?
There is no core charge for this part. You can keep your old module without needing to send it back to us, making the process hassle-free.
My airbag light is on after installing the new BCM. What should I do?
This can happen occasionally. The new BCM needs to be electronically ‘shaken hands’ with the airbag system’s computer (SDM). A professional mechanic with a bi-directional scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
What does this BCM control on my 2004-2007 Savana 1500 Van?
The BCM is the brain for most non-engine related electronics. It manages your interior and exterior lights, power locks and windows, security system, wipers, and the heating and A/C (HVAC) system.
