Restore Your Escalade’s Flawless Performance
Are you dealing with baffling electrical issues in your Cadillac Escalade EXT? One moment the power windows work, the next they don’t. Maybe the security system is acting up, the HVAC controls are unresponsive, or you’re seeing persistent warning lights on the dash. These frustrating problems often point to a single culprit: a failing Body Control Module (BCM). This VIN-programmed BCM is the definitive, dealership-free solution to restore the seamless luxury and functionality you expect from your Cadillac.

Frequently Asked Questions
What does the BCM actually do on my Escalade?
The Body Control Module (BCM) acts as the central computer for your vehicle’s non-engine-related electronics. It manages functions like power windows, door locks, the security system, interior and exterior lighting, wipers, and the HVAC system, ensuring they all work together correctly.
Is this module truly plug-and-play?
Yes. We pre-program the module using the VIN you provide during checkout. This ensures it’s flashed with the correct software and calibrations for your specific Escalade EXT, allowing for direct installation without requiring a trip to the dealership for additional programming.
What if my airbag light is on after I install it?
In some cases, the new BCM may need to be synchronized with the airbag system’s computer (SDM). If the airbag light remains on, a technician will need to perform a ‘Setup SDM Primary Key in BCM’ procedure with a professional-grade scan tool. This is a simple sync procedure, not a full reprogramming.
Do I need to return my old BCM?
No. We do not require a core return for this part. You can keep your old module, which simplifies the process and saves you the hassle and expense of return shipping.
How can I be sure the BCM is my problem?
While professional diagnosis is always best, a failing BCM is a very common cause for multiple, seemingly unrelated electrical issues. If your power accessories, lights, and security system are all acting erratically, the BCM is the most likely culprit.
Will this fit models other than the Escalade EXT?
Yes, this BCM is compatible with a wide range of 2002-2007 GM trucks and SUVs, including the Silverado, Sierra, Tahoe, Yukon, Suburban, and Hummer H2. Please verify the part number and check the full compatibility list on our product page to ensure a perfect fit for your vehicle.
