Restore Your Vehicle’s Electrical System with a Plug-and-Play BCM
Are you chasing electrical gremlins in your Chevy Cruze, Equinox, or Terrain? Flickering lights, malfunctioning power windows, a security system that acts up, or 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 frustration. It’s the central hub for your car’s body electronics, and when it fails, chaos ensues. This isn’t just an inconvenience; it can be a serious safety issue.
We offer a straightforward and reliable solution. This listing is for a replacement BCM, pre-programmed with your vehicle’s exact data. By cloning the information from your original module, we eliminate the need for expensive dealership visits and complex programming procedures. You get a part that is truly plug-and-play, designed to get you back on the road quickly and affordably. Our service for this 2013 Cruze BCM and other compatible models is designed for both professional mechanics and determined DIYers.
A Technician’s Notebook: The Ghost in the Machine
I remember a 2013 Chevy Cruze that came into the shop with the most bizarre symptoms. The owner complained that the radio would switch stations on its own, the interior lights would pulse randomly, and occasionally, the car just wouldn’t start. He had already replaced the battery and checked the alternator. A scan showed a dozen intermittent communication codes (U-codes) pointing in every direction. This is a classic sign of a BCM failure. The module was creating network noise, confusing all the other computers. Instead of a costly diagnostic rabbit hole, we identified the BCM, cloned it to a replacement unit like this one, and had the car running perfectly in an afternoon. This simple swap saved the customer hundreds in diagnostic labor and programming fees.
Is Your GM Vehicle Showing These BCM Failure Signs?
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, your Body Control Module is the likely cause:
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ Interior or exterior lights staying on, flickering, or not turning on.
- ✔ The anti-theft or security system light is illuminated, preventing the car from starting.
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ Wipers activating on their own or not responding to the switch.
- ✔ A dashboard lit up with multiple, unrelated warning lights.
- ✔ Communication error codes, such as U0140, U0155, or other U-series codes, stored in the system.
Your Straightforward BCM Installation Guide
Replacing your BCM is a manageable job. Our cloning service makes the electronic side simple, so you can focus on the physical swap. Here are the general steps:
- Step 1: Safety First. Always disconnect the negative terminal from your vehicle’s battery before working on any electronic components.
- Step 2: Locate the BCM. In most of these vehicles, like the 2013 Cruze, the BCM is located in the driver’s side footwell, behind the kick panel or under the dash. Consult a service manual for the exact location on your model.
- Step 3: Disconnect and Remove. Carefully unplug the electrical connectors. They have locking tabs that need to be depressed. Once disconnected, unbolt the module from its mounting bracket.
- Step 4: Install the New Module. Mount the replacement BCM you received from us and securely reconnect all electrical connectors. Ensure they click into place.
- Step 5: Reconnect and Test. Reconnect the negative battery terminal. Start the vehicle and test all body functions—windows, locks, lights, wipers, etc.—to confirm the repair.
Important Post-Installation Information
While our goal is a 100% plug-and-play experience, some vehicle systems may require a ‘handshake’ with the new BCM. This is normal and easily addressed:
- Airbag System Sync: If the airbag warning 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 recalibration might be necessary to ensure correct brake light and traction control operation.
Disclaimer: Vehicle systems vary. Always have a factory service manual available for reference. If you are unsure about any step, consult a qualified professional.

Frequently Asked Questions
How does the programming service work?
It’s simple. After you purchase, we will contact you with instructions to ship your original BCM to us. Once we receive it, we transfer all the necessary vehicle-specific data to the replacement module. We then ship the plug-and-play replacement back to you, typically within one business day.
Do I need to send my original BCM? Is there a core charge?
Yes, you must send us your original BCM for the data cloning process. This is how we ensure the replacement is 100% plug-and-play for your vehicle. There is no core charge, and you can keep your original module after the service if you wish.
What if my original BCM is water damaged or won’t communicate?
In many cases, even with water damage or communication issues, we can still extract the necessary data. Please contact us before purchasing if your module has severe physical damage so we can assess the likelihood of a successful data transfer.
Will I need special tools to install this 2013 Cruze BCM?
For the physical installation, you’ll only need basic hand tools like a socket set and a trim removal tool. Because our module is pre-programmed, you will not need a dealership-level scan tool for programming. However, as noted, a relearn procedure for the airbag or brake sensor may be required in some cases.
Is this a permanent fix for my car’s electrical problems?
Yes, if the Body Control Module has been correctly diagnosed as the root cause of the issues, replacing it with our programmed unit will provide a lasting and reliable repair, restoring all related functions to normal operation.
