If you’re dealing with bizarre electrical issues in your GM truck or van, you’re not alone. Flickering lights, power windows with a mind of their own, or a security system that randomly prevents your engine from starting—these are classic signs of a failing Body Control Module (BCM). As the central command for your vehicle’s body electronics, a faulty BCM can turn your reliable workhorse into a source of constant frustration. This isn’t just an inconvenience; it can be a major diagnostic headache.
This is the definitive, hassle-free solution. We offer a replacement Programmed GM BCM, part number 15194169, that arrives at your door ready for installation. Simply provide your vehicle’s VIN during checkout, and our technicians will flash the module with the latest, most stable software direct from GM. This critical step ensures all your vehicle’s specific options are recognized, saving you a costly and time-consuming trip to the dealership for programming.
From the Diagnostic Bay
I remember a 2006 Silverado 2500 that came into my shop with a complaint of a dead battery every morning. The owner had already replaced the battery and alternator. After hours of chasing a parasitic draw, we traced it to the BCM. It wasn’t fully going to ‘sleep’ after the key was off, keeping other modules awake and slowly draining the battery. Swapping in a pre-programmed BCM like this one solved the issue instantly. These modules are notorious for internal circuit board failures that create these exact kinds of electrical ‘ghosts’.
Is Your GM Vehicle Showing These Symptoms?
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ Interior dome lights or exterior lamps staying on or not working at all.
- ✔ The security light is illuminated on the dash, possibly causing a no-start condition.
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ Intermittent instrument cluster functionality or warning lights.
- ✔ Diagnostic trouble codes (DTCs) related to communication errors, such as U0140 (Lost Communication With Body Control Module).
A Straightforward Guide to Your BCM Installation
- ✔ Safety First: Always 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 Silverado and Sierra pickups, the BCM is typically found under the driver’s side of the dashboard, near the steering column. On Express and Savana vans, it’s usually located behind the center dash panel.
- ✔ Disconnect and Remove: Carefully unplug the 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 Programmed GM BCM in the same location and securely reconnect all electrical connectors. You should hear a ‘click’ as they lock into place.
- ✔ Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position (without starting the engine) and test all body functions—windows, locks, lights, etc.
- ✔ Perform Relearn Procedures (If Needed): As noted below, some vehicles may require an airbag system sync or brake pedal position relearn if specific warning lights appear. This step often requires a professional-grade scan tool.
Important Post-Installation Information
While this module is delivered ready to install, GM vehicles have integrated safety systems. Please be aware of the following potential procedures:
- Airbag System Sync: If the airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is necessary. This syncs the new BCM with the airbag module and requires a compatible diagnostic tool.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be needed to ensure correct brake light and traction control operation.
- No Core Charge: We make it simple. There is no core charge on this part, so you don’t have to worry about the cost or hassle of sending your old module back.

Frequently Asked Questions
What exactly does a Body Control Module do?
The BCM acts as the brain for your vehicle’s comfort and convenience features. It controls power windows, locks, interior and exterior lights, the alarm system, and communicates with other modules in the vehicle.
Is this BCM really plug-and-play?
Because we program it to your VIN before shipping, it is a direct physical replacement. In most cases, it will function immediately. However, due to integrated vehicle systems, some models may require the additional relearn procedures mentioned if certain warning lights appear.
Why do you need my VIN?
Your Vehicle Identification Number (VIN) allows us to flash the BCM with the exact software and settings your truck or van was built with. This ensures all features work correctly and avoids compatibility issues.
What if my airbag light comes on after I install it?
This is a known possibility. It means the new BCM needs to be electronically ‘introduced’ to the airbag’s computer (SDM). A professional mechanic with a high-level scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Is there a core charge for this part?
No. We do not require you to return your old BCM. There is no core charge or extra hassle involved.
Will this fit my Crew Cab truck?
Based on the fitment data, this specific part number is listed for models excluding Crew Cabs. Please double-check your original part number to ensure compatibility.
