Restore Your Vehicle’s Electrical System with a True Plug-and-Play Solution
Are you battling bizarre electrical problems in your GM vehicle? Flickering lights, unresponsive power windows, or a security system that has a mind of its own? These are classic signs of a failing Body Control Module (BCM). The BCM is the central command for your car’s body electronics, and when it falters, it can create a cascade of frustrating issues. Dealerships often quote a fortune for a replacement and the necessary programming. We offer a smarter, more affordable path forward.
This is a replacement BCM compatible with part number 15299986 and many others. The key to our service is the cloning process. You send us your original BCM, and we professionally transfer all of its critical data—including security information and vehicle-specific options—to this replacement unit. It arrives at your door ready for installation, with the latest GM software updates applied based on your VIN. No extra programming, no expensive trip to the dealer. It’s the most direct way to get your car back to 100%.
A Technician’s Notebook: The Case of the Haunted Impala
A 2009 Chevy Impala rolled into my bay last month with a list of symptoms that sounded like a ghost story. The radio would cut out, the power locks would cycle randomly while driving, and the dash lights would occasionally go dark. The owner had already replaced the battery and checked the main grounds. A scan showed a U0140 code—Lost Communication With Body Control Module. After confirming power and ground to the BCM were solid, it was clear the module itself was failing internally. Instead of a costly new unit from the dealer, we used our cloning service. We transferred the data from his old module to a replacement, and he installed it himself in under an hour. All the ghostly electrical problems vanished instantly. It’s a fix I’ve performed hundreds of times, and it works every time.
Is Your Vehicle Showing These Symptoms?
- ✔ Power windows, mirrors, or door locks working intermittently or not at all.
- ✔ Interior dome lights or exterior lights staying on or not turning on.
- ✔ The anti-theft or security system light is flashing, preventing the car from starting.
- ✔ False warnings on the instrument cluster (e.g., ‘Door Ajar’).
- ✔ Diagnostic trouble codes (DTCs) related to communication errors, such as U0140, U0155, or B1001.
- ✔ Wipers or radio functioning erratically.
A Straightforward Guide to Installation
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the BCM: The module’s location varies by model. It’s typically found under the driver’s or passenger’s side of the dashboard, sometimes behind the glove box or near the center console.
- Disconnect and Remove: Carefully unplug the electrical connectors. They have locking tabs that need to be pressed. Once disconnected, remove the bolts or nuts holding the BCM in its bracket.
- Install the New Module: Seat the replacement BCM into the bracket and secure it with the mounting hardware. Reconnect all electrical harnesses firmly until they click into place.
- Reconnect and Test: Reattach the negative battery terminal. Turn the key to the ‘On’ position and test all body functions—windows, locks, lights, wipers, and radio—to ensure everything is working correctly.
- Perform Relearns (If Needed): In some cases, you may need to perform additional procedures. If the airbag light is on, an ‘Airbag System Sync’ is required. A ‘Brake Pedal Position Relearn’ may also be necessary for proper brake light and traction control operation. These steps typically require a professional scan tool.

Frequently Asked Questions
How exactly does this cloning service work?
After you complete your purchase, we will provide instructions for shipping your original BCM to us. Our technicians will then extract the unique data from your module and flash it onto the replacement unit. This makes the new module an exact electronic copy of your old one, ensuring seamless compatibility. We then ship both your original module and the ready-to-install replacement back to you.
Why do you need my original BCM?
Your original BCM contains vital security information and vehicle-specific option configurations that are unique to your car’s VIN. By cloning this data, we eliminate the need for costly and complex reprogramming by a dealership, which is required for a brand new or junkyard module.
Do I still need to provide my VIN if you’re cloning my module?
Yes. We use your VIN to verify that we are providing the correct hardware and to check for any available GM factory software updates that can be applied during the programming process, ensuring your module has the most stable and reliable software available.
What do I do if my airbag light is on after installation?
This can happen occasionally. It means the new BCM needs to be electronically introduced to the airbag system’s computer (SDM). A professional mechanic with a high-level scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the modules and turn off the light.
Is this a guaranteed plug-and-play solution?
For over 95% of vehicles, yes. Because we are cloning your original data, the module should be plug-and-play. However, as mentioned, some vehicles may require a simple relearn procedure for the airbag or brake pedal position sensor, which requires a scan tool.
What happens if my original module is not communicating at all?
Even if your module is completely dead and won’t communicate with a scan tool, in most cases, our technicians can still directly access the memory chip on the circuit board to recover the necessary data. Please contact us if your module has severe water or fire damage.
