Restore Full Electrical Control to Your GM Truck or SUV
Are you battling bizarre electrical issues in your Cadillac Escalade, Chevy Silverado, or GMC Sierra? Flickering lights, unresponsive power windows, a dead HVAC system, or a frustrating no-start condition are all classic 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 make your truck feel possessed. This genuine OEM-quality BCM, part number 15064149 (interchangeable with 15116066 and others), is the definitive solution to restore order and reliability.
Is Your GM Vehicle Showing These Symptoms?
- ✔ Power windows, door locks, or mirrors work intermittently or not at all.
- ✔ The HVAC blower motor is inoperative or stuck on one speed.
- ✔ Your security system acts up, causing a no-start condition (security light on).
- ✔ The airbag warning light is illuminated, often with a B1001 diagnostic trouble code.
- ✔ Interior or exterior lights (headlights, taillights, dome light) behave erratically.
- ✔ The radio or instrument cluster loses power randomly.

Installation and Post-Install Notes
Installation is straightforward for any DIYer. The BCM is typically located under the driver’s side dashboard, near the steering column. The entire swap takes just a few minutes. Always disconnect the battery before you begin to prevent electrical shorts and help reset the vehicle’s systems. While the module is plug-and-play for most functions, please note the following potential procedures:
- Airbag System Sync: If your airbag light is on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the airbag system to the new BCM.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be required to ensure proper brake light and traction control operation.

Frequently Asked Questions
What does this BCM control on my 2005 Escalade?
The BCM acts as the brain for your vehicle’s body accessories. It manages the power windows, door locks, interior and exterior lighting, security system, wipers, and HVAC controls. When it fails, any of these systems can malfunction.
Is this part really plug-and-play?
Yes, because we program it to your vehicle’s VIN before shipping, it is ready for installation without needing a trip to the dealership for programming. In some cases, as noted above, a post-install procedure like an airbag sync may be needed if that specific warning light is on.
Do I need to return my old BCM?
No. There is no core charge for this part. You can keep your old module, which saves you the time and hassle of a return shipment.
What if my airbag light is still on after installing the new BCM?
This is a known possibility. It means the new BCM needs to be electronically introduced to the airbag system’s computer (SDM). A repair shop with a professional-grade scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to resolve this.
How can I be sure my BCM is the problem?
The most common indicators are multiple, unrelated electrical failures (e.g., windows and radio stop working at the same time) and specific diagnostic trouble codes (DTCs) like B1001. If you are experiencing several of the symptoms listed on this page, a faulty BCM is the most likely cause.
