Is Your Chevy Cruze Experiencing Bizarre Electrical Problems?
If your 2013 Chevrolet Cruze is acting haunted—with flickering lights, malfunctioning power windows, a dead instrument cluster, or even a no-start condition—the culprit is often a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s body electronics, and when it fails, it can cause a cascade of frustrating and seemingly unrelated issues. Simply swapping it with a used one won’t work, as the BCM is programmed specifically to your vehicle’s VIN and options. Dealerships charge a premium for a new module and the subsequent programming. We offer a simpler, more cost-effective solution.
This listing is for a replacement BCM that is professionally programmed using the data from your original module. This cloning service makes the replacement unit a true plug-and-play component, restoring your vehicle’s functionality without the need for expensive dealership tools or programming. You simply send us your original BCM, and we handle the complex data transfer. We then ship you the ready-to-install replacement, getting you back on the road quickly and confidently.
From the Diagnostic Bay
We had a 2013 Cruze come into the shop that was driving the owner crazy. The radio would turn on and off by itself, the dome light would stay on, and occasionally, the car wouldn’t start, with no crank and no communication to the scan tool. The battery was new, and the alternator checked out fine. After chasing wires and checking grounds, we focused on the BCM. We noticed that wiggling the connectors at the BCM (located in the driver’s side kick panel) would sometimes make the problems appear or disappear. This pointed to an internal failure. Instead of a costly new module from the dealer, the owner opted for our cloning service. We sent his original module out, got the programmed replacement back a few days later, plugged it in, and every single electrical gremlin was gone. It’s a textbook example of how a failing 2013 Cruze BCM can mimic a dozen other problems.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Erratic interior or exterior lighting (lights staying on or not turning on).
- ✔ Instrument cluster gauges behaving erratically or not working at all.
- ✔ Security system faults or the anti-theft light staying illuminated.
- ✔ Key fob not working correctly.
- ✔ A no-start or no-crank condition where the battery is known to be good.
- ✔ False warning messages on the driver information center.
- ✔ Communication errors with a diagnostic scan tool.
How Our Simple Mail-In Programming Service Works
- ✔ Place Your Order: Complete your purchase through our secure checkout.
- ✔ Receive Instructions: We will contact you via email with detailed instructions on how to safely remove and ship your original BCM to our facility. Please ensure your contact information is accurate.
- ✔ We Program Your Module: Once we receive your original module, our technicians will extract the vehicle-specific data and flash it onto the replacement BCM. This process ensures 100% compatibility.
- ✔ Receive Your Ready-to-Install Part: We ship the fully programmed replacement BCM back to you. You will receive tracking information once it is on its way. Installation is as simple as plugging it in.
Post-Installation Procedures & Considerations
While our cloning service makes this a plug-and-play installation, some vehicle systems may require a recalibration or sync procedure after the BCM is reconnected. This is standard for many modern vehicles.
- Airbag System Sync: In some cases, the airbag warning light may illuminate after installation. This indicates the new BCM and the SDM (airbag module) need to be synced. A professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
- Brake Pedal Position Relearn: A brake pedal position sensor recalibration might be necessary to ensure proper operation of the brake lights and traction control system. This is also performed with a capable diagnostic tool.
Please consult a factory service manual or a qualified technician if you are unsure about these procedures.

Frequently Asked Questions
What exactly does the Body Control Module do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine related functions. This includes power windows, door locks, interior and exterior lighting, the security system, wipers, and the instrument cluster, among other things.
Why do I need to send my original BCM to you?
The BCM contains critical data unique to your vehicle, including the VIN, security information, and settings for its specific options. By cloning this data from your original module to the replacement, we ensure the new part works perfectly with your car’s existing systems without any additional programming.
Is this a difficult part to install myself?
For most DIY mechanics, the physical installation is straightforward. The BCM is typically located in the driver’s side kick panel area. It involves disconnecting the battery, removing a few trim pieces, and unplugging the electrical connectors. The main challenge is the potential need for post-installation relearn procedures, which may require a professional scan tool.
Will this fix my no-start problem?
If your no-start issue is caused by the BCM failing to recognize the key or communicate with other modules, then yes, a properly programmed replacement BCM will resolve the problem. However, no-start conditions can also be caused by other issues like a bad starter, battery, or ignition switch, so proper diagnosis is key.
What is your turnaround time?
Our programming service is typically completed within 1-2 business days after we receive your original module. Shipping times will vary based on your location and chosen shipping method. We will provide you with a tracking number as soon as your programmed module is shipped back to you.
