Your Escalade EXT Body Control Module Solution
This isn’t just a replacement part; it’s a complete restoration of your vehicle’s core electronic functions. The Escalade EXT Body Control Module is essential for the proper operation of the features you use every day. Our VIN programming service ensures that the module integrates perfectly with your truck’s existing systems, like the powertrain and airbag modules, right out of the box. Installation is straightforward for any DIYer or professional technician. The BCM is typically located under the driver’s side dashboard near the steering column. Simply disconnect the battery, swap the modules, and reconnect. There is no core charge, so you can keep your old part without any hassle.

Frequently Asked Questions
What does a Body Control Module do on a 2003-2006 Cadillac Escalade?
The BCM acts as the main computer for your vehicle’s body electronics. It controls non-engine related functions like power windows, locks, lights, the security system, HVAC blower, and wipers.
Is this BCM difficult to install?
No, the physical installation is very simple. It’s typically located under the steering column and involves unplugging the old module and plugging in the new one. The entire process often takes less than 15 minutes.
Do I need to take my truck to the dealer after installing this part?
No. This module is delivered pre-programmed to your vehicle’s VIN. This eliminates the need for additional, costly programming at a dealership.
What if my airbag light is still on after installation?
If the airbag light remains on, it means the new BCM needs to be synchronized with the airbag system’s Sensing and Diagnostic Module (SDM). This requires a ‘Setup SDM Primary Key in BCM’ procedure with a professional scan tool.
Will this module fit other GM trucks besides the Escalade?
Yes, this BCM is compatible with a wide range of 2002-2007 GM trucks and SUVs, including the Chevrolet Silverado, Tahoe, Suburban, GMC Sierra, and Yukon. Always verify the part number for your specific vehicle.
