Is your GM truck or van suffering from bizarre electrical problems?
If you’re dealing with flickering lights, power windows and locks that have a mind of their own, a security system that won’t behave, or a mysterious battery drain, the culprit is often a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it starts to fail, it can cause a cascade of frustrating and seemingly unrelated issues. Don’t let electrical gremlins sideline your reliable workhorse. This direct-fit BCM is the solution to restore full functionality and peace of mind.
From the Diagnostic Bay
We had a 2005 Silverado 2500 in the shop that was driving the owner crazy. The dome lights would randomly turn on while driving, the radio would shut off, and sometimes the truck wouldn’t start, acting like the battery was dead. The owner had already replaced the battery and alternator twice! After running diagnostics, we traced the issue to a faulty BCM that was creating a parasitic draw and sending erratic signals. Replacing it with a VIN-programmed unit like this one solved every single problem instantly. It’s often the hidden computer, not the obvious part, causing the headache.
The Simple, Reliable Solution for Your 2003-2007 Savana BCM
Forget expensive dealership visits and complex programming procedures. We make the process easy. Simply provide your vehicle’s VIN during checkout, and our technicians will program this BCM with the latest GM software specific to your truck or van. It arrives at your door ready for installation, eliminating the need for special scan tools for the initial setup. This is the most efficient way to get your vehicle back on the road and working correctly. This module is a direct replacement for a wide range of part numbers, including 15167329, 15194169, 15747545, 15136224, 15116065, 15198115, 15136876, and 10367689.
Common Symptoms of a Failing BCM:
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ Erratic interior or exterior lights (flickering, staying on, or not turning on).
- ✔ Malfunctioning security system or horn honking randomly.
- ✔ A persistent parasitic battery drain that kills your battery overnight.
- ✔ Instrument cluster warning lights appearing without cause.
- ✔ Radio or climate control systems not functioning properly.
Installation and Post-Install Notes
While this module is programmed for plug-and-play installation, some vehicles may require a simple relearn procedure for specific systems after the BCM is installed. This is a normal part of the vehicle’s security and safety communications.
- 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 new BCM with your vehicle’s airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be needed to ensure correct brake light operation.
Always consult a factory service manual or a qualified technician for vehicle-specific procedures.
Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that manages and controls electronic accessories like power windows, locks, lights, wipers, the security system, and more. It acts as the central hub for these functions.
Is this BCM ready to install right out of the box?
Yes! Once you provide us with your vehicle’s 17-digit VIN, we program the module with the correct software for your specific vehicle. It will arrive ready to be installed without the need for initial dealer programming.
How do I provide my VIN?
You can add your VIN to the notes section during checkout. If you forget, don’t worry – we will contact you via email after your purchase to request the VIN before we program and ship the module.
What if my airbag light is on after I install the new BCM?
This is not uncommon. It means the new BCM needs to be electronically introduced to the airbag system (SDM). A procedure called ‘Setup SDM Primary Key in BCM’ must be performed with a professional-grade scan tool to clear the light.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module.
