Restore Your Vehicle’s Electrical System with a Reliable BCM
Are you battling bizarre electrical issues in your Buick, Chevy, GMC, or Cadillac? Flickering lights, malfunctioning power windows, a dead instrument cluster, or a car that refuses to start can all point to one culprit: a failing Body Control Module (BCM). As the central command center for your vehicle’s electronics, a faulty BCM can create a cascade of frustrating and hard-to-diagnose problems. This isn’t just an inconvenience; it can affect safety systems like your airbags and traction control. Stop chasing electrical gremlins and get a definitive solution.
We offer a straightforward and cost-effective repair with our professionally programmed BCM, compatible with part numbers like 13577850 and 13578420. Our unique cloning service eliminates the need for expensive dealership visits and complex programming tools. Simply send us your original BCM, and we’ll transfer all the critical vehicle-specific data—including VIN, mileage, and key information—to this replacement module. We ship it back to you ready for installation, making this the simplest way to get your car back to 100% functionality.
From the Diagnostic Bay: The Case of the Haunted Regal
A customer brought in a 2011 Buick Regal with a list of complaints that sounded like the car was possessed. The radio would turn on and off, the interior lights would flicker, and the “Service Airbag” message would pop up randomly. They had already replaced the battery and checked the alternator. In my 20+ years of experience, these scattered, unrelated electrical symptoms almost always point back to the BCM. After connecting my scan tool, I found multiple communication loss codes (U-codes) with various modules. We confirmed the BCM was failing internally. By providing a cloned 2011 Regal BCM, we solved all the issues in one shot, saving the customer hundreds compared to the dealership’s quote for a new module and programming.
Is Your Vehicle Showing These Symptoms?
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, this module is likely the solution you need:
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ Erratic instrument cluster behavior (gauges dropping, warning lights on).
- ✔ Malfunctioning interior or exterior lights (staying on or not turning on).
- ✔ Vehicle security system issues or a no-start condition.
- ✔ Communication error codes, such as U0140, U0155, or other U-series codes.
- ✔ False warnings for systems like ABS, Traction Control, or Airbags.
A Straightforward Guide to Your BCM Replacement
Our cloning service makes this a job that a confident DIYer or any professional mechanic can handle easily. Here’s the process:
- Purchase: Complete your order for this BCM. Please ensure your contact information is accurate.
- We Contact You: We will reach out with detailed instructions and the shipping address for you to send your original module to us.
- Ship Your Original BCM: Carefully package and ship your vehicle’s original BCM to our facility.
- Cloning Process: Upon receipt, our technicians will professionally transfer all necessary data from your old module to this replacement unit.
- Installation: We ship the plug-and-play replacement BCM back to you. Simply disconnect the battery, remove the old BCM (typically found in the driver’s side dash or kick panel), and install the new one. Reconnect the battery and start the vehicle.
Important Post-Installation Information
While our service ensures the BCM is programmed to your vehicle, certain security and safety systems may require a final handshake after installation. Please be aware of the following:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a simple “Setup SDM Primary Key in BCM” procedure is needed. This requires a professional-grade diagnostic tool to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be necessary to ensure brake lights and traction control function correctly. This also requires a capable scan tool.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
What is a BCM cloning service?
Our cloning service is a process where we transfer the exact software, VIN, and security information from your original, failing BCM to this replacement unit. This makes the new module plug-and-play, avoiding the need for expensive programming at a dealership.
Do I need to send my original part to you?
Yes, this service is dependent on you shipping your original BCM to us. We cannot program the replacement module without the data from your original part. We will contact you with shipping instructions after your purchase.
Is there a core charge for this part?
No, there is no core charge. You are not required to send your old part back after receiving the programmed replacement, but we do need it initially for the data transfer.
Will this fix my specific problem?
This part is a solution for failures within the BCM itself. While it resolves the most common electrical issues like those listed above, it’s crucial to ensure a proper diagnosis has been performed. This part will not fix issues related to wiring, sensors, or other modules.
What tools do I need for installation?
Basic hand tools for removing trim panels and accessing the BCM are typically all that’s required for the physical swap. However, as noted, a professional scan tool may be needed for post-installation procedures like the airbag system sync or brake pedal relearn if warning lights appear.
