Restore Full Electrical Function to Your GM Vehicle
If your 2008-2012 Savana 3500 Van is plagued by bizarre electrical problemsâlike flickering lights, malfunctioning power windows and locks, or a dashboard that lights up with random warningsâyou’re likely dealing with a failing Body Control Module (BCM). As the central command center for your vehicle’s body electronics, a faulty BCM can cause a cascade of frustrating and seemingly unrelated issues. This isn’t just an annoyance; it can impact vehicle security and safety systems.
Forget the expensive and time-consuming trip to the dealership. We offer a simple, reliable solution: a replacement BCM with a professional cloning service. By transferring the exact data from your original module to this replacement unit, we provide a true plug-and-play part. It arrives at your door ready for installation, with the latest GM software updates and programmed specifically to your vehicle’s VIN. This process ensures all your original settings and security information are preserved, eliminating the need for costly dealer-exclusive programming tools.
A Technician’s Notebook: The Work Van That Wouldn’t Cooperate
I remember a 2011 Express 3500 (which uses this exact BCM) that came into my shop with a list of complaints that made no sense together. The driver said the dome lights would stay on, the radio would randomly shut off, and sometimes the van wouldn’t start, but only on hot days. The battery and alternator tested fine. A basic scan tool showed a dozen ‘loss of communication’ codes (U-codes) with various modules. This is a classic sign of a BCM failure. The internal communication pathways start to break down, creating electronic chaos. Instead of a multi-day diagnostic nightmare and a huge bill from the dealer, we used a cloned BCM. We had the old one out, sent it for service, and installed the cloned replacement in under an hour of shop time once it arrived. The van was back on the road, fully functional, saving the business owner significant downtime and expense.
Is Your GM Vehicle Showing These Signs of BCM Failure?
A failing BCM can manifest in many ways. If you’re experiencing any of the following, this module is the likely solution:
- â Erratic or non-functional power windows, door locks, or mirrors.
- â Interior or exterior lights that stay on, flicker, or don’t work at all.
- â Intermittent no-start condition where the engine cranks but won’t fire up.
- â Malfunctioning security system or key fob.
- â Warning lights on the dash for ABS, Airbag, or Traction Control.
- â Communication error codes, often in the U-series (e.g., U0100, U0140).
A Straightforward Guide to BCM Installation
Installing your cloned BCM is a manageable job for a DIY enthusiast or any professional mechanic. Our service eliminates the most complex step: programming.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning any electrical work.
- Locate the BCM: On most Savana and Express vans, the BCM is located behind the center dash panel, often near the fuse box area. On other compatible models, it may be under the steering column or on the left-hand side of the dash. A quick search for your specific model will confirm the location.
- Remove the Old Module: Carefully unplug the electrical connectors. They have locking tabs that must be depressed to be released. Unbolt or unclip the module from its mounting bracket.
- Install the New Module: Seat the replacement BCM onto the mounting bracket and securely plug in all electrical connectors. You should hear a click as they lock into place.
- Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position and test all body functionsâlights, locks, windows, radio, etc.âto confirm proper operation.
Post-Installation Checks: What to Expect
In most cases, the vehicle will function perfectly after installation. However, due to the integration of various safety systems, some vehicles may require a simple relearn procedure if a warning light appears:
- Airbag System Sync: If the airbag (SRS) light is on, a ‘Setup SDM Primary Key in BCM’ procedure may be needed. This is a simple task for any shop with a professional-grade scan tool.
- Brake Pedal Position Relearn: On some models, a brake pedal position relearn might be necessary to ensure brake lights and stability control systems operate correctly.
Disclaimer: Always refer to a factory service manual for procedures specific to your vehicle.

Frequently Asked Questions
Frequently Asked Questions
What exactly is a BCM cloning service?
Our cloning service is a process where we transfer the complete software and vehicle-specific data (like VIN, mileage, and key information) from your original, failing BCM to this fully functional replacement unit. This makes the new module an exact electronic copy of your old one, ensuring it works seamlessly with your vehicle without any additional programming.
Will I need to go to the dealer after installing this part?
No. Because we clone your original module’s data, this part is 100% plug-and-play. You will not need to pay for or schedule a visit to the dealership for programming, saving you hundreds of dollars and significant time.
What happens to my original module? Do you keep it?
We always return your original module to you along with the programmed replacement unit. We do not keep customer cores, so you’ll have your original part back.
How do I find my BCM’s part number to ensure a match?
The part number is printed on a sticker directly on the Body Control Module itself. You will need to access the module in your vehicle to visually inspect it and confirm the number matches one from our compatible list.
What if my airbag light is on after installation?
This is uncommon, but if it happens, it means the BCM needs to be synced with the airbag’s Supplemental Deployment Module (SDM). Any professional repair shop with a modern diagnostic scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to resolve this.
Is this a difficult part to replace for a DIYer?
For someone with basic mechanical skills, this is a very manageable job. The main challenge is typically accessing the module, which may require removing a few dash panels. Since our cloning service handles the programming, the electrical part of the job is simply unplugging the old module and plugging in the new one.
