Are you battling frustrating electrical problems in your GM truck or van? A faulty Body Control Module (BCM) is often the culprit behind a host of issues that can make your vehicle feel unreliable. The BCM acts as the central hub for your vehicle’s body electronics, managing everything from your power windows and locks to your interior lighting and security system. When it fails, it can cause a cascade of confusing symptoms. This replacement BCM, part number 15167329, is the definitive solution to restore full functionality and peace of mind.
We make the repair process simple. This module is not just a replacement part; it’s a complete, ready-to-install solution. Upon purchase, you provide us with your vehicle’s VIN, and our experts will program the BCM with the latest GM software specific to your truck or van. This means no expensive trips to the dealership for programming. It arrives at your door ready for a plug-and-play installation.
We had a 2005 Sierra 2500 come in with the weirdest issue: the driver’s side power window wouldn’t work, the radio display would flicker randomly, and the dome light stayed on constantly. The owner had already replaced the window switch and motor with no luck. After a quick scan, we saw multiple communication codes pointing to the BCM. Instead of chasing individual components, we identified the central failure. A new, pre-programmed Silverado Body Control Module fixed all three problems in one shot, saving the customer hundreds in wasted parts and diagnostic time. It’s a classic case of the BCM being the hidden source of multiple electrical gremlins.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that won’t turn on or off.
- ✔ The security system or keyless entry malfunctioning.
- ✔ Warning lights on the dash, such as the airbag or brake light, without a clear cause.
- ✔ Intermittent operation of the radio or instrument cluster gauges.
- ✔ ‘No Communication’ errors when scanning with a diagnostic tool.
Why Choose Our Pre-Programmed Silverado Body Control Module?
This unit is a direct-fit replacement for a wide range of GM trucks and vans, including the Silverado, Sierra, Express, and Savana. It is a reliable and cost-effective alternative to a dealership repair. By programming the module to your VIN before shipping, we eliminate the most complex step of the replacement process. While the installation is straightforward, some vehicles may require a simple relearn procedure for specific systems after the new BCM is connected.
Post-Installation Procedures
Your new BCM is designed to be plug-and-play. However, depending on your vehicle’s specific configuration, you may need to perform one of the following simple relearn procedures with a suitable diagnostic tool:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed to sync the systems.
- Brake Pedal Position Relearn: In some cases, a brake pedal position sensor recalibration may be required to ensure correct brake light and traction control operation.
This BCM is a direct replacement for part numbers: 15167329, 15194169, 15747545, 15136224, 15116065, 15198115, 15136876, and 10367689. Plus, there is no core charge, so you can keep your original module.
Frequently Asked Questions
Do I need to get this BCM programmed by a dealer?
No. We handle all the programming for you before we ship the part. Simply provide your vehicle’s VIN during or after checkout, and it will arrive ready to install.
Where is the BCM located on my 2004 Silverado?
On most 2003-2007 Silverado and Sierra pickups, the BCM is located under the steering column, behind the lower dash panel. On Express and Savana vans, it is typically found in the center of the dash.
What if my airbag light comes on after I install it?
This is a known possibility. The new BCM needs to be synced with the airbag’s Sensing and Diagnostic Module (SDM). A professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Is this a new or used part?
This is a high-quality, tested, and verified used OEM part that has been programmed with the latest vehicle-specific software for reliable performance.
Is there a core charge for my old part?
No, there is no core charge. You are not required to send your old BCM back to us.
Will this fix my power window and lock problems?
If the BCM is the root cause of your electrical issues, then yes, replacing it with this programmed unit will resolve those problems. It is a common solution for erratic power windows, locks, and lighting.
