Are you battling strange and frustrating electrical problems in your GM truck or van? Flickering lights, malfunctioning power windows, a security light that won’t turn off, or random warning messages are all classic signs of a failing Body Control Module (BCM). The BCM is the central computer for your vehicle’s body electronics, and when it fails, it can cause a wide range of confusing issues. This replacement BCM, part number 15194169, is the definitive solution to restore your vehicle’s full functionality.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-working power windows, door locks, and mirrors.
- ✔ Interior or exterior lights that stay on, flicker, or don’t work at all.
- ✔ The security or anti-theft light stays illuminated, potentially causing a no-start condition.
- ✔ False warning lights or messages appearing on the instrument cluster.
- ✔ Inconsistent operation of the HVAC climate control system.
- ✔ Horn or alarm system activating unexpectedly.

Installation & System Re-Sync
This BCM is designed for a straightforward installation, typically located under the steering column or in the center dash area. While it is programmed to your VIN, certain vehicle safety and comfort systems may require a re-synchronization procedure after installation. This is a normal part of replacing a major vehicle computer.
- Airbag System Sync: If the airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional-grade scan tool. This syncs the new BCM with the airbag system’s Sensing and Diagnostic Module (SDM).
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration to ensure correct brake light operation and to satisfy the traction control system.
Please note: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
Do I need to get this BCM programmed by a dealer?
No. We program the module to your vehicle’s specific VIN before we ship it to you. It arrives ready for installation, saving you a trip to the dealership.
What is a core charge?
A core charge is a deposit you pay until you return your old part. This part has no core charge, so you can keep your original module without any extra fees.
Why is my airbag light on after installing the new BCM?
The new BCM needs to be electronically ‘introduced’ to your vehicle’s airbag module (SDM). This requires a ‘Setup SDM Primary Key’ procedure using a professional scan tool to turn off the light.
Where is the BCM located on my 2005 Silverado?
On most 2003-2007 Silverado and Sierra pickups, the BCM is located under the driver’s side of the dashboard, near the steering column. On Express and Savana vans, it is typically behind the center dash panel.
Will this fix my power window and lock problems?
If the switches and motors are good, a failing BCM is the most common cause of erratic power window and lock operation. Replacing it often resolves these types of electrical issues.
