Restore Your Truck’s Electrical System with a Plug-and-Play Solution
Are you chasing electrical gremlins in your 2014 Chevy Silverado or other GM vehicle? Flickering lights, malfunctioning power windows, a temperamental security system, or even a no-start condition can often be traced back to one component: the Body Control Module (BCM). As the central hub for your vehicle’s body electronics, a failing BCM can cause a host of frustrating and unpredictable problems. Simply swapping it with a new or used unit won’t work, as it requires expensive and complex programming at a dealership to sync with your truck’s unique identity.
This is where our expert service comes in. We provide a fully tested BCM (part number 13594692) that is pre-programmed specifically for your vehicle using data from your original module. You simply send us your old BCM, we perform a professional data transfer to the replacement unit, and ship it back to you ready for installation. This process, often called ‘cloning’, makes the replacement 100% plug-and-play, saving you from tow bills, dealer appointments, and high programming fees.
Is Your Truck Showing These Symptoms?
A faulty BCM can manifest in many ways. If you’re experiencing any of the following, a failing BCM is a likely culprit. In my shop, I’ve seen these issues hundreds of times, often accompanied by communication error codes like U0140, U0155, or B1001.
- ✔ Intermittent or non-working power windows, door locks, or interior lights.
- ✔ Horn honking randomly or not working at all.
- ✔ The security or anti-theft light stays on, preventing the engine from starting.
- ✔ Dashboard warning lights appearing and disappearing without reason.
- ✔ Wipers or radio turning on and off by themselves.
- ✔ Inconsistent communication with diagnostic scan tools.
Case Study: A Tricky Diagnosis
A customer brought in his 2014 Sierra 1500, a truck nearly identical to the Silverado platform. He was at his wit’s end. His main complaint was a dead battery every morning. He had already replaced the battery and alternator twice. When we hooked up the scanner, we found intermittent ‘Lost Communication’ codes with half the modules on the truck. The key was that the codes were inconsistent. After checking for wiring issues, we monitored the BCM’s activity overnight. We found the BCM was failing to go into ‘sleep’ mode, keeping other modules awake and causing a constant parasitic draw. A cloned 2014 Silverado BCM from our stock solved the issue completely, saving him from needlessly replacing more parts.
A Straightforward Guide to Installation
Once you receive your programmed module from us, installation is simple. On most GM trucks like the Silverado and Sierra, the BCM is located under the driver’s side of the dashboard, near the steering column.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on any electronic components.
- Locate the BCM: Remove the lower dash panel below the steering wheel to gain access. The BCM is a black box with several large multi-pin connectors.
- Disconnect and Remove: Carefully unplug all electrical connectors. They have locking tabs that need to be depressed. Once unplugged, unbolt or unclip the old BCM from its mounting bracket.
- Install the New Module: Mount your new, pre-programmed BCM in the same location and securely plug in all the connectors. You should hear a ‘click’ as they lock into place.
- Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position and test all functions: lights, windows, locks, radio, etc., before starting the engine.
Important Post-Installation Information
While our cloning service makes this a plug-and-play repair, some vehicle systems may require a quick resync procedure after the battery has been disconnected and the BCM replaced.
- Airbag System Sync: If your airbag warning light is on after installation, a simple ‘Setup SDM Primary Key in BCM’ procedure may be needed. This requires a professional-grade scan tool and syncs the new BCM with the airbag system. This is only necessary if the light appears.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn might be required to ensure your brake lights and stability control systems function correctly. This is also performed with a capable scan tool.
- Disclaimer: Vehicle systems vary. We always recommend consulting a factory service manual or a certified technician if you are unsure about any step.

Frequently Asked Questions
What does your ‘cloning’ service mean?
Cloning is the process of transferring the critical vehicle-specific data (like VIN, mileage, and key information) from your original BCM to the replacement unit we provide. This makes the new module a perfect electronic match for your truck, eliminating the need for dealer programming.
Do I need to send my original part to you?
Yes. For the cloning service to work, we need your original BCM. After you place your order, we will contact you with simple instructions on how to ship it to our facility.
Is there a core charge or do I get my old part back?
There is absolutely no core charge. We only need your original module for the data transfer service. You can keep your original module once the service is complete if you wish.
Where is the BCM located on my 2014 Silverado?
The BCM is typically found under the driver’s side dashboard, to the left of the steering column. You will likely need to remove the plastic knee bolster panel to access it.
What if the airbag light comes on after I install it?
This is an uncommon but possible scenario. It simply means the BCM needs to be electronically ‘introduced’ to the airbag module. A technician with a professional scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to resolve this.
