Restore Full Electrical Control to Your GM Vehicle
Are you battling bizarre and frustrating electrical gremlins in your Savana van or other GM vehicle? Intermittent power windows, flickering lights, a security system that acts on its own, or warning lights that have no clear cause? These aren’t just annoyances; they’re classic signs of a failing Body Control Module (BCM). The BCM is the central hub for your vehicle’s body electronics, and when it falters, it can make your vehicle feel unpredictable and unreliable. Get back in control with this direct-fit, VIN-programmed BCM.
This isn’t just a replacement part; it’s a complete solution. We utilize a professional Cloning Service to transfer the essential data from your original module to this replacement unit. By providing your Vehicle Identification Number (VIN) at checkout, you receive a BCM that is programmed with the latest GM software updates specific to your vehicle’s configuration. This eliminates the need for expensive dealership programming, saving you significant time and money and getting your work van or family vehicle back to full operational status quickly.
A Technician’s Notebook: The Case of the Haunted Work Van
I remember a 2011 Savana 3500 that came into my shop. The owner, a contractor, was at his wit’s end. One day the dome lights wouldn’t turn off, draining the battery. The next, the driver’s side power window and locks would stop working entirely. He’d already replaced the battery and checked fuses. After hooking up my scanner, I saw a slew of communication errors pointing to the BCM (multiple U-codes). Instead of sending him to the dealer for a new module and a hefty programming bill, we ordered a VIN-programmed unit like this one. The install took less than an hour, and because the critical data was already cloned, the van’s systems immediately recognized it. We performed a quick brake pedal position relearn, and he was back on the road, relieved. This is the exact kind of hassle-free fix we offer here.
Common Signs of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ The vehicle’s security system or keyless entry malfunctioning.
- ✔ Horn sounding unexpectedly or not working when pressed.
- ✔ Dashboard warning lights (like ABS or Airbag) illuminating without a related mechanical fault.
- ✔ Diagnostic trouble codes (DTCs) related to communication loss, such as U0140, U0155, or other U-series codes.
A Straightforward Guide to Installation
- ✔ Safety First: Before you begin, always disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- ✔ Locate the BCM: On most Savana and Express vans, the BCM is located behind the center dash panel, often near the fuse block. On other compatible models, it may be under the steering column or on the left-hand (driver’s) side of the dash. A quick search for your specific model will confirm its location.
- ✔ Disconnect and Remove: Unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket and remove it from the vehicle.
- ✔ Install the New BCM: Mount the new, pre-programmed BCM in the same location and reconnect all electrical connectors, ensuring they click securely into place.
- ✔ Post-Installation Steps: Reassemble your dash panels and reconnect the negative battery terminal. Start the vehicle and check for proper function of all accessories. Be aware that some vehicles may require the post-installation procedures noted below.
Important Post-Installation Information
While our cloning service handles the main programming, some vehicle systems may require a ‘handshake’ with the new BCM. This is normal. You may need a professional scan tool to perform the following:
- Airbag System Sync: If your airbag light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed to sync the systems. This is a safety-critical step.
- Brake Pedal Position Relearn: On some models, a recalibration of the brake pedal position sensor is necessary to ensure brake lights and stability control function correctly.
Disclaimer: Vehicle systems vary. We always recommend consulting a factory service manual or a certified technician if you are unsure about any step.

Frequently Asked Questions
Frequently Asked Questions
How does the VIN programming (Cloning Service) work?
After you purchase, you provide us with your vehicle’s 17-digit VIN. We use this to access the correct GM software and vehicle-specific options, then flash this data onto the module before shipping. This ensures it works with your existing keys and options.
Do I need to send my original BCM to you?
No, our service is a true cloning service where we use your VIN to program the replacement. However, we do return your original module to you along with the newly programmed unit. We do not keep your core part.
Is this a guaranteed fix for my electrical problems?
This module will fix issues directly caused by a faulty BCM. If your problems are due to bad wiring, faulty switches, or other components, those will still need to be addressed. A proper diagnosis is always recommended.
What tools are needed for the installation?
Basic hand tools like a socket set and a trim removal tool are usually all that’s required for the physical installation. A professional-grade scan tool may be needed for post-installation relearn procedures on certain models.
Will I need to get new keys made?
No. Because we program the module to your VIN, it is configured to work with your vehicle’s existing security system and keys, saving you a significant amount of money and hassle.
