Restore Your Vehicle’s Electrical System with a Plug-and-Play Solution
Are you battling frustrating electrical gremlins in your GM vehicle? Flickering lights, malfunctioning power windows or locks, a security system that acts up, or even a car that refuses to start can all point to one culprit: a failing Body Control Module (BCM). As a technician with over two decades of experience, I’ve seen how a faulty BCM can turn a reliable vehicle into a source of constant headaches. It’s the central command for your car’s comfort and convenience features, and when it fails, chaos ensues.
This isn’t just a replacement part; it’s a complete, hassle-free repair solution. We offer a professional Cloning Service for this genuine GM Body Control Module. Simply send us your vehicle’s original BCM, and we will expertly transfer all the critical data—including your Vehicle Identification Number (VIN) and specific security information—to this replacement unit. The result? A module that is 100% plug-and-play. You can skip the expensive trip to the dealership, avoid costly programming fees, and get your car back to perfect working order right in your own garage.
A Technician’s Notebook: The Express Van That Baffled a Shop
Just last month, a 2009 Chevy Express 3500 work van was towed to a local shop I consult for. The complaint was bizarre: the dome lights would flicker randomly, the radio would shut off, and occasionally the van wouldn’t crank. The shop had already replaced the battery and checked all the grounds. They were stumped. When I hooked up my pro-level scan tool, I noticed several U-codes (U0140, U0155) indicating a loss of communication with the BCM. Instead of just replacing it and sending the owner to the dealer for a $300+ programming fee, we recommended this cloning service. We cloned the original module, plugged the new one in, and every single issue vanished. The customer saved time, money, and the van was back on the road making money the next day. This is the power of a properly prepared module.
Is Your Vehicle Exhibiting These BCM Failure Signs?
A failing GM Body Control Module can cause a wide range of symptoms. If you’re noticing any of the following, it’s a strong indicator that your BCM needs attention:
- ✔ Erratic or non-functional interior/exterior lights.
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ The security system light stays on, or the alarm goes off randomly.
- ✔ Instrument cluster gauges behaving erratically or going dark.
- ✔ Your key fob is no longer recognized by the vehicle.
- ✔ Diagnostic trouble codes (DTCs) related to communication errors, such as U0140, U0151, or other B-series codes.
- ✔ A no-start or intermittent no-crank condition where the engine doesn’t even try to turn over.
Your Straightforward BCM Installation Guide
Installing your cloned BCM is a manageable task for a DIYer with basic tools. The location varies by model (see fitment list), but the general process is similar.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes to ensure all systems are powered down.
- Locate the BCM: On most listed vehicles, the BCM is located under the driver’s side or center of the dashboard. You may need to remove a lower dash panel for access.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that must be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- Install the New Module: Mount your new, cloned BCM in the same location and securely re-attach the electrical connectors. You should hear a ‘click’ as they lock into place.
- Reconnect and Test: Re-attach the negative battery terminal. Turn the key to the ‘On’ position and test all body functions: lights, locks, windows, radio, etc. Start the vehicle to ensure it runs correctly.
- Perform Relearns (If Needed): As noted in our procedures, you may need a scan tool to perform an Airbag System Sync or a Brake Pedal Position Relearn if related warning lights appear.

Frequently Asked Questions
What is a cloning service?
Cloning is the process of reading the essential software and security data from your original BCM and writing it onto the replacement module. This makes the new module an exact digital copy, allowing it to work in your vehicle without any additional programming.
Do I need to send my original BCM to you?
Yes. For the cloning service to be successful, we need your original (old) module to extract the vehicle-specific data. We will return your original module along with the newly programmed replacement.
What happens if I install it and the airbag light comes on?
This is a possibility on some models. It means the BCM and the airbag module (SDM) need to be electronically re-introduced. This requires a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure, which is a quick process for any qualified mechanic.
Will this fix my no-start problem?
If your no-start issue is caused by the BCM failing to recognize your key or manage the anti-theft system, then yes, this cloned module will resolve the problem. However, no-start conditions can also be caused by other components like the starter, battery, or fuel system.
Is this a difficult part to replace myself?
For most DIYers, this is a very manageable job. The BCM is typically located under the dash and held in by a few bolts or clips. The main challenge is accessing it, which may require removing a plastic trim panel. No special tools are usually required for the physical swap.
