Restore Control and End Electrical Frustrations in Your GM Vehicle
If you’re dealing with bizarre electrical issues in your Silverado, Sierra, Express, or Savana, you know how maddening it can be. One minute the power windows work, the next they don’t. The security light stays on, preventing your truck from starting. These aren’t just annoyances; they’re signs that the central command center for your vehicle’s body electronics—the Body Control Module (BCM)—is failing. This isn’t a problem you have to live with. We offer a reliable, direct-fit solution: a replacement GM BCM 15167329, professionally programmed and ready for installation.
Forget the hassle and expense of a dealership visit. We take the complexity out of the repair. Simply provide us with your vehicle’s VIN at checkout, and our technicians will program the module with the latest official GM software specific to your truck or van. This ensures all factory-intended functions operate correctly right out of the box, making the installation process as smooth as possible for both seasoned mechanics and first-time DIYers.
A Technician’s Notebook
I remember a 2005 Silverado 2500 that came into my bay with a classic case of BCM failure. The owner was at his wit’s end. The dome lights would flicker randomly, the radio would cut out, and sometimes the truck just wouldn’t crank, leaving him stranded. A quick scan showed a slew of communication codes (U-codes) pointing to the BCM. These modules, especially on work trucks that see a lot of vibration and temperature swings, often develop microscopic cracks in the internal solder joints. We swapped in a VIN-programmed BCM, and it was like the truck was new again. Every function was restored, and the customer drove away with a reliable vehicle. This is the exact fix we provide.
Is Your GM Vehicle Showing These Symptoms?
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that flicker, stay on, or don’t work at all.
- ✔ The security or anti-theft light is illuminated, causing a no-start condition.
- ✔ Gauges on the instrument cluster behaving erratically or not working.
- ✔ Horn sounding randomly or not working when pressed.
- ✔ Diagnostic trouble codes (DTCs) related to lost communication, such as U0140, U0155, or U0164.
- ✔ The radio or climate control system turns on and off by itself.
Your Straightforward BCM Installation Guide
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- ✔ Locate the BCM: On Silverado and Sierra pickups, the BCM is typically located under the driver’s side of the dashboard, near the steering column. For Express and Savana vans, it’s usually found behind the center dash panel.
- ✔ Disconnect and Remove: Carefully unplug the electrical connectors. They have locking tabs that need to be depressed. Once unplugged, remove any bolts or screws holding the old BCM in place and take it out.
- ✔ Install the New BCM: Mount your new, pre-programmed BCM in the same location and secure it with the original hardware. Firmly reconnect all electrical connectors, ensuring they click into place.
- ✔ Reconnect and Verify: Reconnect the negative battery terminal. Turn the key to the ‘ON’ position and test all body functions: lights, windows, locks, horn, and wipers to confirm the repair.
Important Post-Installation Information
While our GM BCM 15167329 is programmed for your VIN, some vehicle systems may require a ‘handshake’ with the new module. Please be aware of the following potential procedures:
- Airbag System Sync: If your airbag warning light is on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the airbag system with the new BCM.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be necessary to ensure correct brake light and traction control operation.
Please Note: Specific requirements can vary. We always recommend consulting a factory service manual or a qualified technician for guidance.

Your Vehicle Identification Number (VIN) allows us to program the BCM with the exact software and settings your specific vehicle requires. This ensures compatibility and proper function of all electronic features, saving you a trip to the dealer for programming.
For most functions, yes. Because it’s pre-programmed to your VIN, the core functions will work upon installation. However, as noted, some vehicles may require an additional relearn procedure for the airbag or brake systems, which requires a professional scan tool.
No. This product comes with no core charge. You can keep your old module, which is helpful if you ever need to reference its original part number.
An illuminated airbag light after installation is not a defect. It simply means the BCM needs to be electronically synced with the vehicle’s Sensing and Diagnostic Module (SDM). This requires a ‘Setup SDM Primary Key in BCM’ procedure, which can be performed by any professional shop with a compatible high-level scan tool.
While less common, a failing BCM can sometimes interfere with the communication network that the Transmission Control Module (TCM) uses, potentially causing communication-related shifting issues. However, erratic shifting is more commonly caused by the TCM itself, solenoids, or mechanical issues.
