Frequently Asked Questions
What does a Body Control Module do on an Escalade EXT?
The BCM acts as the central computer for your truck’s body electronics. It manages non-engine related functions like power windows, door locks, interior and exterior lights, the security system, wipers, and the HVAC blower motor, ensuring all these comfort and convenience features work together seamlessly.
Is this BCM difficult to install?
Installation is straightforward for someone with basic mechanical skills. The BCM is typically located under the steering column. The process involves disconnecting the battery, removing a few trim panels, and swapping the electrical connectors from the old module to the new one. Most installations take less than 30 minutes.
Will I need to go to the dealership after installation?
No. Because this module is pre-programmed to your vehicle’s VIN number, it is ready for installation right out of the box. This allows you to bypass the need for expensive programming or calibration services from a dealership or specialized shop.
What if the airbag light comes on after I install it?
In some cases, the new BCM may need to be synced with the airbag system’s computer (SDM). If the airbag light appears, a technician will need to perform a “Setup SDM Primary Key in BCM” procedure using a professional-grade scan tool. This is a simple sync procedure, not a full reprogramming.
How do I know this is the right part for my truck?
This 2004 Cadillac Escalade EXT body control module is guaranteed to fit 2003-2006 models. It also replaces numerous original part numbers, including 15136877. You can confirm compatibility by matching your old part number to the list provided or by using our vehicle fitment tool.
