Is Your GM Truck or SUV Plagued by Electrical Gremlins?
If you’re dealing with flickering lights, malfunctioning power windows, a haywire security system, or other bizarre electrical issues in your 2012-2014 GM vehicle, a failing Body Control Module (BCM) is the most likely culprit. The BCM is the central command center for your vehicle’s body electronics, and when it starts to fail, it can cause a cascade of frustrating and seemingly unrelated problems. This isn’t just an inconvenience; it can affect the safety and security of your vehicle.
From the Diagnostic Bay
We had a 2013 Silverado 2500 in the shop that was driving the owner crazy. The dome lights would randomly turn on while driving, the key fob would work one minute and not the next, and the radio display would flicker. The owner had already replaced the battery and checked fuses with no luck. After connecting our diagnostic tool, we saw multiple communication fault codes pointing to a network issue. Instead of chasing wires for hours, we went straight to the BCM. A quick swap with a pre-programmed module like this one resolved every single issue instantly. It’s a classic case of a failing central computer causing widespread electronic chaos.

This means it arrives ready for installation, with the latest GM software updates, ensuring seamless integration with your truck’s existing systems. You get a fully functional module without the need for expensive dealer-only programming tools.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-working power windows, door locks, and mirrors.
- ✔ Interior or exterior lights that won’t turn on or off.
- ✔ The security system or alarm randomly activating or not working at all.
- ✔ Intermittent windshield wiper operation.
- ✔ Instrument cluster warning lights illuminating incorrectly.
- ✔ Remote keyless entry (key fob) failure.
- ✔ Communication errors (U-codes) when scanned with a diagnostic tool.
Why Choose Our 2012-2014 GM Truck BCM?
This isn’t just a replacement part; it’s a complete solution. By providing us with your VIN at checkout, you ensure that the module you receive is a perfect match for your vehicle’s specific configuration and options. This critical programming step is what makes for a successful and straightforward repair, restoring your vehicle’s functions to factory specifications.
Installation and Post-Install Procedures
The BCM is typically located under the steering column on the driver’s side. Physical installation involves disconnecting the battery and carefully swapping the electrical connectors from the old module to the new one. While our programming handles the majority of the setup, some vehicles may require additional steps after installation:
- Airbag System Sync: If the airbag warning light is on after installation, a “Setup SDM Primary Key in BCM” procedure is needed. This requires a professional-grade scan tool to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: In some cases, a brake pedal position sensor recalibration may be necessary to ensure proper brake light and traction control operation.
We always recommend consulting a factory service manual or a qualified technician if you are unsure about any part of the installation process. This 2012-2014 GM Truck BCM is a direct replacement for part numbers 22846365, 22737275, and 22846364, and fits a wide range of Sierra, Silverado, Tahoe, Suburban, Yukon, and Escalade models.
