Restore Your Truck’s Electrical System with a Plug-and-Play BCM
Are you tired of chasing electrical gremlins in your GM truck or van? Intermittent power windows, locks that have a mind of their own, or a security light that won’t turn off are classic signs of a failing Body Control Module (BCM). As the nerve center for your vehicle’s body electronics, a faulty BCM can cause a host of frustrating and unpredictable problems. This isn’t just an inconvenience; it can affect your vehicle’s security and daily usability. We offer a reliable, straightforward solution: a replacement BCM, part number 15194169, that arrives at your door fully programmed to your vehicle’s VIN.
I remember a 2006 Silverado 2500 that came into my bay with a classic parasitic battery drain. The owner had replaced the battery twice, but it would still be dead every few mornings. After checking the alternator and running a draw test, I started pulling fuses. The draw disappeared when I pulled the BCM fuse. The internal circuits of the original module were failing to go to ‘sleep’ after the truck was shut off, slowly killing the battery. Installing a pre-programmed BCM like this one not only solved the battery drain but also fixed his intermittently working dome light—a problem he’d forgotten to even mention. These modules are central to so many functions, and a quality replacement is key to a lasting repair.
Is Your Truck Showing These Symptoms?
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, this module is likely the solution you need:
- ✔ Power windows, mirrors, or door locks not working or operating erratically.
- ✔ Interior or exterior lights flickering, staying on, or not turning on at all.
- ✔ The anti-theft or security light is illuminated on the dash, possibly causing a no-start condition.
- ✔ Unexplained battery drain that leaves you with a dead battery overnight.
- ✔ Horn honking randomly or not working when pressed.
- ✔ Communication error codes, such as U0140 (Lost Communication With Body Control Module), stored in the system.
Your Straightforward BCM Installation Guide
Installing your new 2003-2007 Sierra 2500 BCM is a manageable job for a confident DIYer. Since we program the module before shipping, you can skip the expensive trip to the dealership. Just follow these general steps:
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the BCM: On most trucks (Silverado/Sierra), the BCM is located under the driver’s side of the dashboard, near the steering column. On vans (Express/Savana), it’s typically found behind the center dash panel.
- Remove Trim Panels: Carefully remove any plastic trim or panels necessary to access the module.
- Disconnect and Remove: Unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the old module from its mounting bracket.
- Install the New BCM: Mount your new, pre-programmed BCM in the same location and reconnect all the electrical harnesses securely. Ensure they click into place.
- Reconnect and Test: Reinstall any trim panels you removed. Reconnect the negative battery terminal and test all functions—windows, locks, lights, etc.—to confirm the repair.
Post-Installation Note: In some cases, additional steps may be needed. If your airbag light is on, a professional scan tool is required to perform the ‘Setup SDM Primary Key’ procedure. A ‘Brake Pedal Position Relearn’ may also be necessary. Always consult a factory service manual for instructions specific to your vehicle.

Frequently Asked Questions
What exactly does a Body Control Module do?
The BCM acts as the central computer for your vehicle’s non-engine related electronic accessories. It controls functions like your power windows, door locks, interior and exterior lighting, security system, and horn.
Does this module need to be programmed by a dealer?
No! That’s the best part. We program the module to your vehicle’s specific VIN before we ship it to you. This makes the installation process much simpler and saves you a trip to the dealership.
How do I provide my VIN?
After you complete your purchase, you will need to send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot ship your order until we receive your VIN for programming.
What is a core charge, and do I have to pay one?
A core charge is a deposit you pay until you return your old part. We do not have a core charge on this item, so you can keep your original module without any extra fees or hassle.
My airbag light came on after installing the BCM. What should I do?
This can happen occasionally. The new BCM needs to be synced with the airbag system’s Sensing and Diagnostic Module (SDM). This requires a professional-grade scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure.
Will this fix my truck’s no-start problem?
If your no-start issue is caused by the factory anti-theft system being activated due to a faulty BCM, then yes, this module will resolve that problem.
