Tired of Unpredictable Electrical Gremlins?
Is your Cadillac, Chevy, or GMC acting possessed? One day the power windows refuse to work, the next the radio is on the fritz, and the dashboard is lit up with random warning lights. These frustrating and seemingly unrelated issues often point to one central culprit: a failing Body Control Module (BCM). The BCM is the nerve center for your vehicle’s comfort and convenience features, and when it starts to go, it can make driving a maddening experience. Dealerships will often quote a sky-high price for a new module plus mandatory programming fees, leaving you with a hefty bill.
We offer a smarter, more affordable solution. This is a fully tested replacement Body Control Module that comes ready for installation thanks to our professional cloning service. You simply send us your original BCM, and we transfer all of its critical data—including the VIN, key information, and specific options—to this replacement unit. The result? A true plug-and-play module that restores full functionality without any need for a trip to the dealer for expensive programming.
A Technician’s Notebook
I remember a 2015 Silverado that came into the shop with a laundry list of bizarre complaints. The owner said the turn signals worked intermittently, the dome light would stay on, and sometimes the truck wouldn’t recognize the key fob. He’d already replaced the battery and checked all the fuses. A quick scan showed a dozen communication codes (U-codes) pointing to the BCM. Instead of a costly new module and hours of programming, we used a cloned unit. The customer sent us his faulty BCM, we transferred the data, and sent the replacement back. He installed it in his driveway in under an hour, and every single issue was resolved. It’s a perfect example of how the right part and process can save hundreds of dollars and a massive headache.
Is Your Vehicle Exhibiting These BCM Failure Signs?
A faulty BCM can manifest in numerous ways. If you’re experiencing any of the following, this module is likely the solution you need. Look out for common diagnostic trouble codes (DTCs) like U0140, U0155, or B1001.
- âś” Power windows, locks, or mirrors operating erratically or not at all.
- âś” Interior or exterior lights flickering, staying on, or not turning on.
- âś” The security system engaging randomly or preventing the car from starting (anti-theft light on).
- âś” Key fob not being recognized or remote start failing.
- âś” Wipers or horn activating on their own.
- âś” Inaccurate gauge readings on the instrument cluster.
- âś” No communication with the BCM when using a diagnostic scan tool.
Your Straightforward BCM Swap Guide
Our cloning service makes the physical installation simple. Once you receive the programmed module from us, you can get your vehicle back on the road by following these general steps. The BCM location varies by model, so confirm its position in your specific vehicle (e.g., under the steering column, in the dash, or behind a pillar).
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on any electronic components.
- Locate the Original BCM: Find the old BCM in your vehicle. It’s a small black box with several large electrical connectors.
- Disconnect and Remove: Carefully unplug all the wiring harnesses from the module. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket and remove it.
- Install the New Module: Mount your new, pre-programmed BCM in the same location. Securely plug in all the wiring harnesses, ensuring each one clicks firmly into place.
- Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position and test all body functions—windows, locks, lights, wipers, etc.—to confirm the repair was successful.
Important Post-Installation Information
While our service eliminates the need for initial programming, some vehicle systems may require a ‘handshake’ with the new BCM. This is standard procedure and can sometimes be required.
- Airbag System Sync: If the airbag (SRS) warning light is on after installation, a simple ‘Setup SDM Primary Key in BCM’ relearn procedure will be needed. This requires a professional-grade scan tool and syncs the airbag system with the new BCM.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure perfect brake light and traction control operation.
Disclaimer: Vehicle systems vary. We always recommend consulting a factory service manual or a certified technician if you are unsure about any step. No core return is necessary; you can keep your original part.

Frequently Asked Questions
How does the programming service work?
After you place your order, we will provide you with instructions to ship your original BCM to us. Once we receive it, our technicians will extract the vehicle-specific data and flash it onto the replacement module. We then ship the plug-and-play replacement back to you.
Do I need to send my keys with the module?
No, you do not need to send your keys. All the necessary security information is stored within the BCM itself, which we transfer directly during the cloning process.
Is this a guaranteed fix for my vehicle’s problems?
This part is a solution for issues directly caused by a faulty BCM. While it resolves the vast majority of electrical problems listed, proper vehicle diagnosis is key. Ensure your issue isn’t caused by wiring, sensors, or other components.
How long does the whole process take?
We typically program and ship your replacement module within 1-2 business days of receiving your original unit. The total time will depend on shipping times to and from our facility.
Do I need to return my old BCM after installation?
No, there is no core charge for this item. You can keep your original module after you’ve installed the replacement.
