Are you battling frustrating electrical problems in your GM truck or van? Issues like malfunctioning power windows, erratic door locks, flickering lights, or a persistent security warning are often caused by a failing Body Control Module (BCM). The BCM acts as the central hub for your vehicle’s body electronics, and when it goes bad, it can create a cascade of confusing symptoms. This replacement BCM, part number 15167329, is the definitive solution for a wide range of 2003-2007 GM vehicles, including the Silverado, Sierra, Express, and Savana.
We take the guesswork and hassle out of the repair process. Unlike a standard replacement that requires an expensive trip to the dealership for programming, this module arrives at your door fully programmed to your vehicle’s specific VIN. Simply provide us with your VIN after purchase, and our technicians will flash the module with the latest GM software updates. This ensures a seamless, plug-and-play installation, restoring full functionality to your vehicle’s comfort and convenience features.
From the Diagnostic Bay
We had a 2005 Silverado 2500 in the shop where the owner had already replaced the driver’s side window motor twice, but the window would still work intermittently. He was convinced he kept getting faulty motors. After a quick scan, we saw communication fault codes with the BCM. Instead of throwing more parts at it, we swapped in a VIN-programmed BCM. Instantly, the window, locks, and even the dome light that he hadn’t mentioned started working perfectly. It’s a classic case where the BCM was the true root of the problem, not the individual components it controls.
Common Symptoms of a Failing BCM
- ✔ Power windows, mirrors, or door locks operating erratically or not at all.
- ✔ Interior or exterior lights (headlights, dome lights) staying on or not turning on.
- ✔ The security or anti-theft system light is illuminated, and the vehicle may not start.
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ Dashboard gauges behaving erratically or providing false readings.
- ✔ Radio or climate control systems malfunctioning.

This module is a direct replacement for multiple part numbers, including 15167329, 15194169, 15747545, and more, ensuring broad compatibility. By ordering from us, you bypass the need for expensive diagnostic tools for programming. While the physical installation is straightforward for a DIYer or professional mechanic, please be aware of potential post-installation procedures. Depending on your vehicle’s specific configuration, an ‘Airbag System Sync’ or ‘Brake Pedal Position Relearn’ may be necessary if related warning lights appear. These procedures require a professional-grade scan tool to complete. There is no core charge for this part, so you can keep your original module.
Frequently Asked Questions
What does the Body Control Module (BCM) do?
The BCM is a computer in your vehicle that controls and monitors a wide range of electronic accessories not related to the engine, such as power windows, locks, lights, security system, wipers, and more.
Is this BCM difficult to install?
The physical installation is typically straightforward, involving unplugging the old module (usually located under the steering column or in the center dash) and plugging in the new one. The key benefit here is that our module comes pre-programmed, eliminating the most complex step of the process.
How does the VIN programming work?
After you place your order, you will need to provide us with your vehicle’s 17-digit VIN. Our technicians use this number to load the correct software and vehicle-specific settings onto the BCM before we ship it to you.
Do I need to send my old part back?
No. This product comes with no core charge, so you are not required to return your original BCM.
What if my airbag light is on after installation?
If the airbag light illuminates, it means the new BCM needs to be synced with the airbag system’s computer (SDM). This requires a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure.
