Tired of Your Truck’s Electrical Gremlins?
Are you dealing with flickering dashboard lights, power windows that have a mind of their own, or a security system that randomly prevents your truck from starting? These aren’t just annoyances; they’re classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics. When it starts to fail, it can cause a cascade of frustrating and unpredictable problems. In my 20+ years of diagnostics, I’ve seen water intrusion from a leaky windshield or simple internal component fatigue turn a reliable workhorse into a source of daily headaches. This isn’t a problem you have to live with.
This is a direct-fit replacement Body Control Module, a solution for part number 15116065 and its interchanges. The best part? We handle the complicated part for you. Before we ship it, our technicians will program the module with the latest GM software, perfectly matched to your vehicle using your VIN. This eliminates the need for an expensive trip to the dealership for programming, saving you time and money. You get a component that’s ready to install right out of the box, restoring the function and reliability you depend on.
From the Diagnostic Bay: The Case of the Haunted Silverado
I remember a 2006 Silverado 2500 that came into my shop with the strangest collection of symptoms. The radio would turn on and off by itself, the dome light would flicker while driving, and the horn would chirp randomly when locking the doors with the fob. The owner was convinced his truck was possessed. After checking the main grounds and finding no issues, I connected my scan tool. It was showing multiple communication loss codes (U-codes) pointing to the BCM. A quick inspection under the dash revealed the culprit: a fine layer of corrosion on the BCM connectors from a previously spilled soda. We swapped in a pre-programmed BCM, and every single ghost in the machine vanished. It’s a perfect example of how one central module can create widespread chaos.
Is Your GM Vehicle Showing These Symptoms?
A faulty BCM can manifest in many ways. If you’re experiencing any of the following, this module is the likely solution:
- ✔ Power windows, mirrors, or door locks operating intermittently or not at all.
- ✔ Interior or exterior lights flickering, staying on, or not working.
- ✔ The security or anti-theft light is on, causing a no-start condition.
- ✔ The horn sounds at random or the panic alarm goes off unexpectedly.
- ✔ Instrument cluster gauges behaving erratically or warning lights appearing for no reason.
- ✔ Communication error codes stored, such as U0140, U0155, or U0164.
- ✔ The air conditioning compressor clutch won’t engage.
A Straightforward Guide to Your BCM Installation
Installing your new BCM is a manageable job for a confident DIYer. The location can vary between trucks and vans, so verify its position before you begin.
- Safety First: Disconnect the negative terminal from your vehicle’s battery and wait a few minutes to ensure all systems are powered down.
- Locate the BCM: On most Silverado and Sierra pickups, you’ll find it under the driver’s side of the dashboard, near the steering column. On Express and Savana vans, it’s typically located in the center dash area.
- Disconnect and Remove: Carefully unplug all electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- Install the New Module: Mount your new, pre-programmed BCM in the same position as the old one. Firmly reconnect all electrical connectors, ensuring each one clicks securely into place.
- Power Up: Reconnect the negative battery terminal. Your vehicle is now ready for the final steps.
Important Post-Installation Procedures
Because this module is central to many systems, a couple of quick relearn procedures may be needed after installation. This is normal and ensures all related components communicate correctly with the new BCM.
- Airbag System Sync: If your airbag warning light is illuminated after the swap, a simple ‘Setup SDM Primary Key in BCM’ procedure is required. This syncs the BCM with the airbag module and can be done with a bi-directional scan tool.
- Brake Pedal Position (BPP) Relearn: On some models, a BPP sensor relearn might be necessary to ensure brake lights and stability control systems function correctly. This is also performed with a capable diagnostic tool.
- No Core Charge: You can keep your old module, as there is no core charge or need to return it.
Disclaimer: Vehicle systems vary. Always refer to a factory service manual for procedures specific to your exact year, make, and model.

Frequently Asked Questions
How do I provide my VIN for programming?
After you complete your purchase, simply send us a message with your vehicle’s 17-digit VIN. We cannot ship your order until we receive this information, as the programming is essential for the module to function in your vehicle.
Do I absolutely need a scan tool after installation?
Not always, but it’s possible. Many vehicles will operate correctly immediately after installation. However, if the airbag light comes on or brake light functions are incorrect, a relearn procedure with a professional-grade scan tool will be necessary to resolve it.
What exactly does a Body Control Module do?
The BCM is a computer that manages the non-engine related electronic functions in your vehicle. This includes power windows, power locks, the security system, interior and exterior lighting, wipers, and even the A/C compressor clutch.
Is this a difficult part to replace myself?
For someone with basic mechanical skills, it’s very manageable. The main challenges are working in a tight space under the dashboard and carefully unplugging the connectors. Since we pre-program the unit, you skip the most difficult step which requires specialized computer equipment.
Why is your module a better choice than going to the dealer?
Our solution offers significant value. You receive a quality component that is pre-programmed with the latest software and shipped to your door. This saves you the cost of the dealer’s diagnostic and programming labor fees, as well as the hassle of getting your vehicle to a service center.
Is there a core charge for this part?
No. We do not require you to send your old BCM back. There is no core charge associated with this purchase.
