Restore Full Electrical Function to Your GM Truck or SUV
Are you battling bizarre electrical issues in your Hummer H2, Silverado, or Tahoe? Flickering lights, unresponsive power windows, a dead HVAC system, or a persistent airbag light are common signs of a failing Body Control Module (BCM). The BCM is the central command for your vehicle’s body electronics, and when it fails, it can cause a cascade of frustrating problems. This genuine GM 15116066 BCM is the definitive solution, pre-programmed to your vehicle’s VIN for a true plug-and-play repair.
Is Your Vehicle Showing Signs of a Bad BCM?
A faulty BCM can manifest in numerous ways. Look out for these common symptoms:
- ✔ Intermittent or non-working power windows, door locks, or interior lights.
- ✔ HVAC system malfunctions, such as a blower motor that won’t turn on or is stuck at one speed.
- ✔ An illuminated airbag warning light, often with a B1001 diagnostic trouble code.
- ✔ Security system errors, including no-start or crank-no-start conditions.
- ✔ Unpredictable behavior from windshield wipers or exterior lighting.
- ✔ A variety of communication DTCs stored in the vehicle’s computer system.
The Plug-and-Play Solution: A Pre-Programmed 2003-2007 HUMMER H2 BCM
Don’t waste time and money at the dealership. This module arrives at your door fully programmed with the latest GM software updates tailored to your specific Vehicle Identification Number (VIN). This critical step ensures that the BCM communicates flawlessly with your vehicle’s other electronic systems right out of the box. No need for expensive scan tools or additional programming fees. It’s built to strict OEM standards for lasting durability and performance, backed by a one-year warranty.
Simple Installation and Post-Install Notes
Installation is straightforward for the DIY mechanic. On the Hummer H2, the BCM is located on the left-hand side of the dash. For most other compatible GM trucks and SUVs, it’s found under the steering column. Simply disconnect the battery, swap the modules, and reconnect. While most functions will be restored immediately, please note:
- Airbag System: If your airbag light remains on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the systems.
- Brake System: Some models may require a ‘Brake Pedal Position Relearn’ to ensure correct brake light and traction control operation.
Best of all, there is no core charge. You can keep your old part without the hassle of returning it.
Frequently Asked Questions
What does the Body Control Module do on my Hummer H2?
The BCM acts as the central hub for your vehicle’s body electronics. It controls non-engine related functions like power windows, locks, lights, wipers, the security system, and the HVAC climate control system.
Is this BCM ready to install right out of the box?
Yes. We program the module to your vehicle’s VIN before shipping. This ensures it is ready for a plug-and-play installation without requiring a trip to the dealership for additional programming.
Where is the BCM located on a 2003-2007 Hummer H2?
On the Hummer H2, the BCM is typically located on the left-hand side of the dashboard, accessible from underneath. On most compatible Silverado, Sierra, and Tahoe models, it’s under the steering column.
What if the airbag light is on after I install the new BCM?
This is a normal security measure. The new BCM needs to be electronically ‘introduced’ to the airbag system. A technician with a professional scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Do I need to send my old part back?
No. There is no core charge or requirement to return your original module.
