Solve Persistent Electrical Problems in Your GM Van or Truck
If your 2004-2007 Chevrolet Express 1500 Van is experiencing a host of bizarre, unrelated electrical issues, the Body Control Module (BCM) is the most likely culprit. As the central nervous system for your vehicle’s body electronics, a failing BCM can cause chaos—from flickering interior lights and a dead radio to a security system that prevents your van from starting. This isn’t just an annoyance; for a work vehicle, it’s downtime that costs you money. This replacement BCM, part number 15194170, is the definitive solution, restored to full functionality through our expert cloning service.
Unlike standard pre-programmed modules, our cloning service transfers the exact data from your original BCM to this replacement unit. This means all your vehicle-specific settings, security information, and options are perfectly mirrored. The result is a true plug-and-play component that eliminates the need for expensive dealership programming or complex relearn procedures. Get your workhorse back on the road with confidence and restore the reliable operation you depend on every day.
Case Study: The Contractor’s Intermittent No-Start
A local plumber brought in his ’06 Express 2500, a van identical in its electronics to the 1500. His complaint was maddening: some mornings the van wouldn’t start, the security light would flash, and the power locks would act erratically. He’d already replaced the battery and checked the ignition switch. In my shop, I’ve seen this exact scenario dozens of times. We pulled the BCM, and even a visual inspection of the board showed signs of corrosion on a few solder points—a common failure on these work vans. By providing a cloned 2004-2007 Express 1500 BCM, we had him back on the job the same afternoon, saving him a tow to the dealer and days of lost work.
A Straightforward Guide to BCM Installation
Replacing the BCM in your Express van is a job most DIYers or any professional can handle in minutes. The key is our cloning service, which makes the electronic side of the job seamless.
- Step 1: Locate Your Original BCM. In most Express and Savana vans, the BCM is located in the center of the dash, often behind a lower access panel.
- Step 2: Disconnect the Power. Before unplugging any electronics, always disconnect the negative terminal from your vehicle’s battery to prevent electrical shorts.
- Step 3: Remove the Old Module. Carefully unplug the electrical connectors from the BCM. They have locking tabs that need to be depressed. Once unplugged, unbolt or unclip the module from its mounting bracket.
- Step 4: Send Us Your Module. Package your original BCM securely and send it to us. We perform the cloning service and send both your original module and the ready-to-install replacement back to you.
- Step 5: Install the Cloned BCM. Simply mount the new module and plug in the connectors. Reconnect your battery. Your van should start and operate with all its original functions restored.
Common Symptoms of a Failing GM BCM
A faulty BCM can manifest in numerous ways. If your vehicle is showing these signs, it’s time to consider a replacement. This is especially true if you’ve already checked fuses and relays.
- ✔ Intermittent or non-functional HVAC controls, including a blower motor that won’t turn on or off.
- ✔ The dreaded airbag warning light, often accompanied by diagnostic trouble codes (DTCs) like B1001 (Option Configuration Error).
- ✔ Erratic power accessories: windows that don’t work, door locks cycling on their own, or interior/exterior lights staying on or not working at all.
- ✔ Security system faults, such as a flashing security light on the dash and a no-crank, no-start condition.
- ✔ Communication errors with other modules, leading to a dashboard full of warning lights.

Frequently Asked Questions
What exactly is a “Cloning Service”?
Cloning is a process where we transfer the complete software and vehicle-specific data (like VIN, mileage, and key information) from your original BCM to the replacement unit. This makes the new part an exact electronic copy of the old one, ensuring 100% compatibility without any additional programming.
Do I need to take my van to the dealer after installation?
No. Because we clone your original module’s data, you can skip the dealership entirely. This saves you time, towing fees, and expensive programming charges. It’s designed to be a true plug-and-play fix.
Will this fix my airbag light?
If the airbag light is caused by a BCM failure (like DTC B1001), this will resolve the root cause. In some cases, a post-installation procedure called “Setup SDM Primary Key in BCM” may be needed with a high-end scan tool to sync the modules and clear the light.
Is this part difficult to install myself?
For someone with basic mechanical skills, the installation is very straightforward. It involves removing a dash panel, unplugging a few connectors, and swapping the modules. The entire physical process typically takes less than 15 minutes.
What is your core policy?
We do not require a core deposit. Our cloning service requires your original module to transfer data. After the service is complete, we always return your original BCM along with the newly cloned, ready-to-install unit.
