Restore Your Truck’s Electrical System and Get Back to Work
Are you battling strange and frustrating electrical problems in your GM truck or van? Flickering lights, malfunctioning power windows and locks, a security system that acts up, or even a vehicle that refuses to start can all point to a failing Body Control Module (BCM). Don’t let these electrical gremlins keep your reliable vehicle off the road. This fully programmed BCM is the definitive, hassle-free solution to restore your truck’s proper function and your peace of mind.
Common Symptoms & Your Solution
A faulty BCM can create a cascade of confusing issues. If you’re experiencing any of the following, this module is your answer:
- Interior or exterior lights that stay on, flicker, or don’t work at all
- Power windows, door locks, or mirrors operating intermittently or not at all
- The security light is on, and the vehicle won’t start (Passlock issues)
- Erratic or non-functional instrument panel gauges
- Blower motor or climate control problems
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We handle the complex part by programming the module to your vehicle’s specific VIN before it ships.

From the Technician’s Bench: Why a Programmed Module Matters
As a technician, I’ve seen countless hours wasted trying to diagnose electrical chaos caused by a bad BCM. These modules are the central hub for your truck’s body electronics, and when they fail from heat, vibration, or age, the symptoms can be maddening. Simply swapping in a used BCM from a junkyard won’t work—it’s programmed for a different vehicle and will cause even more problems. Our service bridges that gap. By providing a quality, tested programmed GM 15136876 BCM, we give you a dealership-level fix at a fraction of the cost and time. You’re not just buying a part; you’re buying a reliable repair that gets the job done right the first time.
Simple Ordering Process
- Confirm this part fits your vehicle using the compatibility list.
- Complete your purchase.
- Reply to our follow-up email or add a note to your order with your vehicle’s VIN.
- We program the module and ship it directly to you, ready for installation.
Important Post-Installation Information
In some cases, your vehicle may require a simple relearn procedure after the new BCM is installed. These can typically be performed by a qualified technician with a professional scan tool:
- Airbag System Sync: If the airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed to sync the systems.
- Brake Pedal Position Relearn: This may be necessary to ensure proper brake light and traction control operation.
These potential requirements are a normal part of replacing a central computer module. Our programmed GM 15136876 BCM handles the most critical step, making the final process as smooth as possible.
Frequently Asked Questions
How does the programming process work?
After you place your order, you provide us with your 17-digit Vehicle Identification Number (VIN). We use this VIN to access the latest official GM software for your specific vehicle configuration. We then flash this software onto the BCM, making it a perfect electronic match for your truck before we ship it.
Do I need special tools to install this BCM?
The physical installation typically only requires basic hand tools to access the module (often located under the steering column or in the center dash). However, as noted, a professional scan tool may be required for post-installation procedures like the airbag system sync or brake pedal relearn if your vehicle requires them.
Will this fix my specific electrical problem?
This BCM is the direct solution for a wide range of common electrical failures. If you are experiencing multiple issues listed in the symptoms section (erratic lights, power accessory failure, etc.), a faulty BCM is the most likely cause. This module is designed to correct those root failures.
What is the difference between a BCM and an ECU/ECM?
The Body Control Module (BCM) manages the vehicle’s body electronics—things like power windows, locks, lights, and the security system. The Engine Control Unit (ECU) or Engine Control Module (ECM) manages engine-related functions like fuel injection, ignition timing, and emissions.
How do I find my VIN?
Your VIN is a 17-digit number located on a tag on the driver’s side of the dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
