Tired of Bizarre Electrical Problems in Your GM Vehicle?
If you’re dealing with flickering lights, power windows with a mind of their own, a dead dashboard, or a car that refuses to start, you’re likely facing a failing Body Control Module (BCM). As a technician with over 20 years of experience, I’ve seen how a faulty BCM can turn a reliable car into a source of constant frustration. It’s the central hub for your vehicle’s comfort and convenience features, and when it goes bad, it can create a cascade of confusing symptoms. This isn’t just an inconvenience; it can affect vehicle security and safety systems.
Forget the expensive trip to the dealership that involves buying a new module, paying for towing, and then shelling out hundreds more for programming and key relearning. We offer a streamlined, cost-effective solution. This is a professionally programmed BCM, ready for installation in your vehicle. We use the data from your original module to configure this replacement unit, making it a true plug-and-play fix. All your vehicle’s specific options and security information are transferred, ensuring seamless integration. This service for your 2012 Regal BCM saves you time, money, and the headache of complex programming procedures.
From the Diagnostic Bay: The Case of the Intermittent Equinox
A customer brought in a 2012 Chevy Equinox (which uses this same BCM family) with a truly baffling issue. The radio would randomly turn off, the turn signals would stop working, and occasionally, the power locks wouldn’t respond. They had already replaced the battery and checked all the fuses. After connecting my scan tool, I noticed several U-codes (communication loss codes) pointing to the BCM. Instead of a hard failure, the module was failing intermittently due to internal circuit board corrosion—a common issue. By providing a cloned BCM, we had the vehicle fixed and back to the customer the next day, bypassing the week-long wait and high cost quoted by the local dealer.
Is Your Vehicle Showing These Electrical Gremlins?
- ✔ Power windows, door locks, or interior lights operating erratically or not at all.
- ✔ The security or anti-theft light is flashing, preventing the car from starting.
- ✔ Dashboard warning lights (like ABS or Airbag) are on for no apparent reason.
- ✔ The radio or climate control system is unresponsive.
- ✔ Communication error codes (like U0140, U0155) are stored in other modules.
- ✔ The vehicle won’t start, but the battery and starter are confirmed to be good.
Your Straightforward BCM Installation Guide
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- ✔ Locate Your BCM: The location varies by model (see our fitment list). Common spots include behind the driver’s or passenger’s side dash, in the kick panel, or under the center console.
- ✔ Remove the Original BCM: Carefully disconnect all electrical connectors. They have locking tabs, so be gentle. Then, unbolt or unclip the module from its mounting bracket.
- ✔ Ship Us Your Module: After purchase, we will contact you with simple instructions for shipping your original BCM to our facility. Please ensure your contact information is correct at checkout.
- ✔ Post-Installation Checks: Start the vehicle and test all functions (windows, locks, lights, radio). Refer to the post-installation procedures section if any warning lights appear.

Important Post-Installation Information
Because we are transferring your vehicle’s original data, most installations require no additional steps. However, in some cases, certain security systems may need to be re-synced. This is standard procedure for this type of repair.
- Airbag System Sync: If the airbag light is on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the airbag system with the new BCM.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be required to ensure correct brake light and traction control operation.
- No Core Charge: You can keep your old module. There is no core charge or need to return it after the cloning service is complete.
Disclaimer: Vehicle systems vary. We always recommend consulting a factory service manual or a qualified professional if you are unsure about any step of the process.
Your Questions Answered
Frequently Asked Questions
How does the cloning service work?
After you place your order, we will provide instructions to mail your original BCM to us. We extract the unique vehicle data from it and flash it onto the replacement BCM. This makes the new module a perfect match for your car, eliminating the need for dealership programming.
Do I need to send my keys with the BCM?
No, you do not need to send your keys. All the necessary security information is stored within the BCM itself, and we will transfer it directly during the cloning process.
How long does the service take?
We typically program and ship the replacement BCM back to you within 1-2 business days of receiving your original module. You will receive a tracking number as soon as it ships.
Will this fix my specific problem?
This service corrects issues caused by a faulty BCM. If your vehicle exhibits the symptoms listed (erratic lights, locks, no-start, etc.) and you’ve ruled out other causes like a bad battery or fuses, a failing BCM is the most likely culprit.
Is this a guaranteed plug-and-play solution?
Yes, for over 99% of installations. By cloning your original data, the replacement BCM is ready to install and function immediately. The only exceptions are rare cases where a post-install procedure, like an airbag sync, is needed, which requires a professional scan tool.
