Is your 2003-2006 Cadillac Escalade suffering from bizarre electrical problems?
If you’re dealing with flickering lights, a malfunctioning climate control system, or power windows and locks that have a mind of their own, a failing Body Control Module (BCM) is the most likely cause. The BCM is the central command center for your vehicle’s body electronics. When it fails, it can create a cascade of confusing and frustrating issues. This OEM-quality replacement BCM, part number 15137393, is the definitive solution to restore full functionality and reliability to your luxury SUV.
Symptoms of a Failing Escalade BCM
- ✔ Unresponsive or erratic power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that won’t turn on or off, or that flicker intermittently.
- ✔ HVAC and climate control systems that blow air at the wrong temperature or not at all.
- ✔ An active security light on the dash, or a no-start condition where the engine cranks but won’t fire.
- ✔ The airbag warning light is illuminated, often with diagnostic trouble codes like B1001.
- ✔ Inconsistent windshield wiper operation.

This module is built to strict OEM standards for lasting performance and is a direct replacement for part numbers 15137393, 15116066, 15198116, and others listed in the fitment guide.
Installation and Post-Install Considerations
Installation is straightforward for the DIY mechanic. The BCM is typically located under the driver’s side dashboard, near the steering column. Simply disconnect the battery, remove the old module, and plug this new one in. While it’s designed for plug-and-play operation, some vehicles may require a ‘Setup SDM Primary Key in BCM’ procedure if the airbag light remains on. This requires a professional-grade scan tool to sync the new BCM with the airbag system. There is no core charge, so you can keep your old part without any hassle.
