Is Your Sierra 1500 Plagued by Electrical Gremlins?
If your 2014 GMC Sierra 1500 is experiencing bizarre electrical issues like flickering lights, malfunctioning power windows, a dead battery for no reason, or warning lights that won’t go away, the culprit is often a failing Body Control Module (BCM). The BCM is the central command center for your truck’s body electronics, and when it starts to fail, it can create a cascade of frustrating and unpredictable problems. Don’t let a faulty module keep your truck off the road. This is a direct replacement solution, programmed specifically for your vehicle.
Common Symptoms of a Failing 2014 Sierra 1500 BCM
A failing Body Control Module can manifest in numerous ways. If you’re noticing any of the following, it’s a strong indicator that your BCM needs attention:
- ā Intermittent or non-working power windows, door locks, or mirrors.
- ā Interior or exterior lights that stay on, flicker, or don’t work at all.
- ā Erratic behavior from the dashboard gauges or instrument cluster.
- ā The security system acting up, preventing the truck from starting (anti-theft light flashing).
- ā Unexplained battery drain that leaves you with a dead battery.
- ā Horn honking unexpectedly or not working when needed.
- ā HVAC (heating and A/C) controls becoming unresponsive.

Post-Installation Procedures
While our goal is a seamless installation, some GM vehicles may require minor recalibration procedures after the BCM is installed. These are typically simple and can be performed with a capable diagnostic scan tool.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed to sync the airbag system with the new BCM. This is only required if the light is on.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be necessary to ensure proper brake light and traction control functionality.
Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.
Frequently Asked Questions
What does the BCM actually do on my Sierra?
The Body Control Module (BCM) acts as the central computer for your truck’s non-engine related functions. It controls the power windows, locks, lights, security system, horn, wipers, and more. When it fails, these systems can become unreliable.
Why is cloning my original BCM the best option?
Cloning transfers your truck’s unique VIN, key codes, and option settings to the replacement module. This makes the new part plug-and-play, avoiding the need for expensive and complex programming at a dealership, which is required for a brand new BCM.
How long does the cloning service take?
Once we receive your original module, the cloning and processing time is typically just 1-2 business days. We then ship the replacement module back to you promptly.
Is this part difficult to install?
The BCM is usually located under the steering column on the driver’s side. Installation involves disconnecting the battery, removing a few trim panels, and swapping the electrical connectors. It’s a manageable job for a DIYer with basic tools.
Will this BCM fit other vehicles?
Yes, this BCM, part number 13594692, is compatible with a wide range of GM vehicles including the Silverado, Tahoe, Suburban, Corvette, CTS, and Escalade from similar model years. Please verify your original part number against our compatibility list.
