Is Your 2014 Sierra 1500 Experiencing Bizarre Electrical Problems?
If your truck’s lights are flickering, the power windows are acting up, or you’re seeing strange warning messages on the dash, you’re likely dealing with a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s electronic accessories. It manages everything from the interior lights and power locks to the security system and instrument cluster. When it starts to fail, it can cause a cascade of frustrating and seemingly unrelated issues that can be difficult to diagnose.
From the Diagnostic Bay
We had a 2014 Sierra 1500 in the shop last month with a classic case of BCM failure that the owner had been chasing for weeks. The initial complaint was an intermittent ‘Service 4WD’ message, but then the radio would randomly shut off, and the dome lights would stay on, draining the battery. The owner had already replaced the battery and alternator, thinking it was a power supply issue. After a quick scan, we saw multiple communication codes pointing directly to the BCM. A failing BCM can mimic a bad battery or alternator by causing parasitic draws. Replacing it with a properly programmed unit solved all the electrical gremlins at once, saving the customer from further unnecessary parts replacements.
Symptoms of a Failing GM Body Control Module
- ✔ Intermittent or non-functional power windows, locks, or mirrors.
- ✔ Erratic behavior from the instrument cluster, such as flickering gauges or warning lights.
- ✔ Interior or exterior lights staying on or not turning on at all.
- ✔ The vehicle’s security system malfunctioning or preventing the engine from starting.
- ✔ Radio or infotainment system randomly turning off or on.
- ✔ False warning messages appearing on the driver information center (e.g., ‘Service StabiliTrak’, ‘Service 4WD’).
- ✔ A parasitic battery drain that kills the battery overnight.

Installation and Post-Install Notes
The BCM in your 2014 Sierra 1500 is typically located under the steering column on the driver’s side. While installation is straightforward, please note the following potential post-installation procedures:
- Airbag System Sync: In some cases, the airbag warning light may illuminate after installation. This requires a ‘Setup SDM Primary Key in BCM’ procedure using a professional scan tool to sync the modules.
- Brake Pedal Position Relearn: A brake pedal position sensor relearn might be necessary to ensure proper brake light and traction control operation.
Disclaimer: Specific procedures can vary. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
What exactly does the BCM do in my truck?
The Body Control Module (BCM) acts as a central computer for your truck’s body electronics. It controls non-engine related functions like power windows, locks, lights, wipers, the security system, and the instrument cluster.
Is this really a plug-and-play part?
Yes. Because we clone the data from your original BCM to the replacement unit, it will arrive ready to install without any additional programming. This saves you a costly trip to the dealership. Some minor relearn procedures, like for the brake pedal sensor, may be required after installation.
How long does the programming service take?
We typically program and ship your replacement module within 1-2 business days of receiving your original BCM. The total time depends on shipping transit times to and from our facility.
What if I can’t send my original BCM?
This service requires your original BCM to transfer the vehicle-specific data. Without it, we cannot program the replacement module to work with your truck’s unique configuration and security system.
My original part number is slightly different, but my vehicle is on the list. Will it work?
Please check the list of compatible part numbers provided: 13594692, 13594768, 13593214, 13580690, 13591519, 13594769. If your part number is on this list, this module is the correct replacement for your vehicle.
