Restore Your Vehicle’s Electrical System with a Reliable, Programmed BCM
Are you chasing electrical gremlins in your GM truck or van? Flickering lights, power windows 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 central hub for your vehicle’s body electronics, a faulty BCM can cause a host of frustrating and seemingly unrelated issues. I’ve seen it hundreds of times in the shop: a perfectly good engine that won’t start or a dashboard that lights up like a Christmas tree, all because this one module has failed.
This isn’t just a replacement part; it’s a direct solution. We take the hassle and high cost of dealership visits out of the equation. Simply provide us with your vehicle’s VIN after purchase, and we will program this BCM with the latest GM software specifically for your truck or van. It arrives at your door ready for installation, saving you time, money, and the headache of coordinating a tow to a shop for programming. This is the smart, efficient way to get your vehicle back to 100% functionality.
A Technician’s Notebook
A 2005 Silverado 2500 came into the bay with a complaint that was all over the map. The owner said sometimes the radio wouldn’t work, the dome light would stay on, and occasionally the truck wouldn’t crank. He’d already replaced the battery and checked the alternator. A scan showed a handful of ‘U’ codes, specifically a U0140 (Lost Communication With Body Control Module). This is the smoking gun. Instead of shotgunning parts, we went straight to the BCM. After swapping in a new programmed module, every single one of the ghost-like electrical issues disappeared. This is a prime example of how a failing Programmed GM BCM 15167329 can mimic a dozen other problems.
Common Signs of a Failing BCM
- ✔ Erratic or non-functional interior/exterior lights (headlights, dome lights, dash lights).
- ✔ Power windows, door locks, or mirrors not working correctly.
- ✔ The security system light stays on, preventing the vehicle from starting.
- ✔ The horn sounds randomly or doesn’t work at all.
- ✔ Communication Diagnostic Trouble Codes (DTCs), such as U0140, are present.
- ✔ Wipers operate intermittently or get stuck in one position.
A Straightforward Guide to Installation
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning any electrical work.
- ✔ Locate the BCM: On most Silverado and Sierra pickups, you’ll find it under the steering column, behind the lower dash panel. For Express and Savana vans, it’s typically located in the center of the dash.
- ✔ Remove the Old Module: Carefully unplug the electrical connectors. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the old BCM from its mounting bracket.
- ✔ Install the New BCM: Mount your new, pre-programmed BCM in the same location. Securely plug in all the electrical connectors, ensuring they click into place.
- ✔ Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position and test all body functions—lights, locks, windows, radio, etc.
- ✔ Perform Relearn Procedures (If Needed): As noted below, some vehicles may require an Airbag System Sync or a Brake Pedal Position Relearn if specific warning lights appear. This often requires a professional scan tool.
Post-Installation Notes
This Programmed GM BCM 15167329 is designed for a simple installation. However, due to the complexity of modern vehicle systems, a couple of additional steps may be required:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a compatible diagnostic tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On certain models, the brake pedal position sensor may need to be recalibrated to ensure correct brake light and traction control operation.

Frequently Asked Questions
Do I need to do any programming myself?
No. This module arrives fully programmed to your vehicle’s VIN. You just need to provide the VIN at checkout, and we handle all the software flashing before it ships.
What is a core charge? Do I need to send my old part back?
There is absolutely no core charge. You can keep your old BCM, which saves you the time and expense of return shipping.
Is this a difficult part for a DIYer to install?
The physical replacement is straightforward for most DIY enthusiasts with basic tools. It involves removing a dash panel and unplugging connectors. The most important part is being aware that some models may require a relearn procedure with a scan tool for the airbag or brake systems after installation.
How do I know if this Programmed GM BCM 15167329 is the right part?
The best way is to match the part number from your original module to 15167329 or one of the interchangeable numbers listed. You can also use our detailed fitment list to confirm your vehicle’s year, make, and model.
Will this fix my ‘Service 4WD’ light?
While the BCM communicates with many systems, a ‘Service 4WD’ message is more commonly caused by the Transfer Case Control Module (TCCM) or the encoder motor/sensor. It’s best to get a diagnostic scan to confirm the source of the fault before ordering.
