Are you battling frustrating electrical gremlins in your Chevrolet Express Van, Silverado, or GMC Sierra? Flickering lights, malfunctioning power windows, a dead HVAC system, or a security light that prevents your vehicle from starting are all classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can cause a wide range of perplexing issues. This OEM-quality GM 15116066 BCM is the definitive solution, arriving pre-programmed to your vehicle’s specific VIN for a true plug-and-play repair.
Is Your GM Vehicle Showing Signs of BCM Failure?
A faulty BCM can manifest in numerous ways. If you’re experiencing any of the following symptoms, a replacement module is likely the solution you need:
- ✔ Intermittent or non-functional HVAC controls and blower motor.
- ✔ Power windows, door locks, or mirrors that work sporadically or not at all.
- ✔ An illuminated airbag warning light, often accompanied by DTC B1001.
- ✔ Erratic interior or exterior lights, including headlights and turn signals.
- ✔ Security system malfunctions, causing a no-start condition.
- ✔ A cluster of seemingly unrelated diagnostic trouble codes (DTCs).

Simply disconnect the vehicle’s battery, remove the old module, plug in the new one, and reconnect the battery.

Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM acts as the main computer for your vehicle’s non-engine related functions. It controls the power windows, locks, interior and exterior lights, wipers, HVAC system, and the anti-theft security system.
Is this BCM ready to install right out of the box?
Yes! We pre-program this module with your vehicle’s VIN before shipping. This ensures it’s plug-and-play, with no additional dealership programming required for most functions.
Where is the BCM located on a 2005 Chevy Express Van?
On the 2004-2007 Express and Savana vans, the BCM is typically found in the center of the dashboard, accessible from below. On most trucks and SUVs like the Silverado or Tahoe, it’s under the steering column.
Will this fix my airbag light with a B1001 code?
A faulty BCM is a common cause of this code. Replacing it often resolves the issue, but some vehicles may require a post-installation ‘SDM Key Setup’ with a professional scan tool to sync the new BCM with the airbag system and turn off the light.
Do I need to send my old part back?
No. We do not require a core return for this part. There is no core charge, so you can simply keep or dispose of your old module.
