Restore Full Functionality to Your GM Vehicle
Is your 2014 Corvette, Sierra, Tahoe, or other compatible GM vehicle experiencing a host of frustrating electrical problems? Issues like flickering lights, malfunctioning power windows, a dead battery overnight, or a security system that won’t cooperate are often traced back to a single component: a failing Body Control Module (BCM). The BCM acts as the central command center for your vehicle’s body electronics. When it fails, it can create a cascade of seemingly unrelated problems, making diagnosis a nightmare. This listing offers a simple, effective, and permanent solution: a replacement GM Body Control Module, part number 13594692, that is professionally programmed with the data from your original unit.
Diagnosing a Faulty GM Body Control Module
A failing BCM doesn’t always present a clear check engine light. Instead, it manifests as a collection of electrical gremlins that can disrupt your driving experience. If your vehicle is exhibiting several of the symptoms below, a faulty BCM is the most likely culprit. Ignoring these signs can lead to further complications, including no-start conditions or complete loss of interior electronic functions.
From the Diagnostic Bay
We recently had a 2015 GMC Sierra 1500 in the shop that was driving the owner crazy. The horn would honk randomly, the interior dome lights would stay on, and the radio would shut off intermittently. The owner had already replaced the battery twice, thinking it was a power drain issue. After running diagnostics, we pinpointed the BCM. Instead of a costly and complex dealer replacement requiring multiple programming sessions, we performed our cloning service. We transferred the data from his failing BCM to one of our replacement units. After a quick 15-minute installation, every single electrical issue was gone. The truck was back to normal, and the customer was thrilled to have a reliable vehicle again.
Common Symptoms of BCM Failure
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ Interior or exterior lights staying on or not turning on at all.
- ✔ Erratic behavior from the dashboard gauges or warning lights (like the airbag or security light).
- ✔ The vehicle’s security system preventing the engine from starting.
- ✔ Unexplained battery drain that kills the battery overnight.
- ✔ Malfunctioning keyless entry or remote start features.
- ✔ Wipers or radio turning on and off by themselves.
How Our Plug-and-Play Programming Service Works
Dealerships will sell you a new module that requires expensive, vehicle-specific programming. Our solution bypasses this complexity. We perform a direct data transfer, or ‘cloning’, from your original BCM to the replacement unit. This process copies all the critical information, including the VIN, security keys, and specific options your vehicle came with from the factory. The result is a true plug-and-play module that requires no additional programming upon installation.

- We Program & Ship: Upon receipt, we will clone the data to the replacement GM Body Control Module and ship it back to you, typically within one business day. You’ll receive tracking information as soon as it’s on its way.
Important Post-Installation Information
While our goal is a seamless installation, some GM systems may require a quick sync procedure after the new BCM is installed. These are not programming steps but rather ‘handshakes’ between modules.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional scan tool. This syncs the airbag system with the new BCM.
- Brake Pedal Position Relearn: In some models, a brake pedal position sensor recalibration might be necessary to ensure correct brake light operation and traction control function.
Please consult a factory service manual or a qualified technician for detailed guidance specific to your vehicle.
Frequently Asked Questions
Why do I have to send in my original BCM?
Your original BCM contains the unique programming for your vehicle’s VIN, security system, and specific options. By cloning this data, we ensure the replacement module is a 100% plug-and-play match, avoiding costly dealer programming.
Is this part difficult to install?
The BCM is typically located under the driver’s side dashboard. Installation is generally straightforward, involving disconnecting the battery, removing a few trim panels, and unplugging the electrical connectors. Most DIY mechanics can complete the job in under an hour.
What is the turnaround time for the programming service?
We pride ourselves on a fast turnaround. Once we receive your original module, we typically program the replacement and ship it back out within 24-48 business hours.
Will this fix my specific electrical problem?
This programmed BCM will resolve any issue directly caused by a faulty BCM. If your vehicle exhibits multiple symptoms from the list above, it is highly likely that this is the solution you need.
Do I need to do any programming after I install it?
No. Our cloning service makes the module ready to install right out of the box. In some rare cases, a simple relearn procedure as mentioned in the description may be needed, but this is not the same as full programming.
