Restore Your GM Truck’s Electrical System and Drive with Confidence
Are you dealing with a frustrating flurry of electrical problems in your Chevrolet, GMC, or Cadillac truck or SUV? Flickering lights, a dead A/C blower, power windows with a mind of their own, or a persistent airbag light can make your reliable vehicle feel unpredictable. These are classic signs of a failing Body Control Module (BCM). This genuine GM 15116066 BCM is the definitive, hassle-free solution. It arrives expertly programmed to your vehicle’s specific VIN, making installation a simple plug-and-play process that gets you back on the road without a costly trip to the dealership.
Common Symptoms & Your Solution
A failing BCM can cause a cascade of seemingly unrelated issues. If you’re experiencing any of the following, this module is your fix:
- Intermittent or completely non-functional HVAC controls and blower motor.
- An illuminated airbag warning light, often with Diagnostic Trouble Code (DTC) B1001.
- Erratic power windows, door locks, or interior/exterior lighting.
- Security system malfunctions that can lead to a no-start condition.
- Various communication errors or body-related DTCs stored in the vehicle’s computer.
Instead of chasing down individual electrical gremlins, replacing the central hub—the BCM—restores order to the entire system. This programmed 15116066 BCM is engineered to resolve these issues by restoring proper communication between all your vehicle’s essential electronic components.

Frequently Asked Questions
What does “VIN Programmed” actually mean?
It means we load your vehicle’s specific Vehicle Identification Number (VIN) and its corresponding factory software onto the BCM before we ship it. This ensures the module recognizes your vehicle’s security system and specific features (like power seats, sunroof, etc.), allowing it to work correctly right out of the box without any additional dealer programming.
Is this a difficult part to install myself?
For most of the compatible vehicles, the BCM is located under the driver’s side dashboard, near the steering column. It is held in by a few clips or bolts and has several electrical connectors. With basic hand tools, most DIYers can swap the module in under 15 minutes. We always recommend disconnecting the battery’s negative terminal before starting.
My airbag light is on. Will this fix it?
A faulty BCM is a very common cause for the airbag light and code B1001. Replacing it will often solve the problem. However, in some cases, a post-installation procedure called “Setup SDM Primary Key in BCM” must be performed 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 BCM back?
No. There is absolutely no core charge or need to return your original module. You can keep it or dispose of it at your convenience.
Will this BCM fit my 2005 GMC Sierra 2500?
Yes, this module fits a wide range of GM trucks and SUVs from 2002-2007, including the GMC Sierra 2500. Please refer to the detailed compatibility list on this page to confirm your specific model and year for a perfect fit.
