2003-2006 Escalade ESV BCM Body Control Module 15137393

Restore Full Electronic Function to Your Cadillac

Are you experiencing a cascade of strange electrical issues in your 2003-2006 Cadillac Escalade ESV? From flickering lights and malfunctioning power windows to a dead HVAC system or a persistent airbag light, these problems often point to a single culprit: a failing Body Control Module (BCM). The BCM acts as the central nervous system for your vehicle’s body electronics, and when it fails, it can make your luxury SUV feel unpredictable and unreliable. This genuine OEM-quality BCM, part number 15137393, is the definitive solution to restore your vehicle’s functionality and peace of mind.

Symptoms of a Failing Body Control Module

A faulty BCM can manifest in numerous ways. If you’re noticing any of the following, it’s a strong indicator that your module needs replacement:

• ✔ Intermittent or non-working power windows, door locks, or interior/exterior lights.
• ✔ HVAC system failures, such as a blower motor that won’t turn on or erratic temperature control.
• ✔ An illuminated airbag warning light, often accompanied by diagnostic trouble codes like B1001.
• ✔ Security system malfunctions, including no-start conditions where the engine won’t crank.
• ✔ Erratic windshield wiper operation or failure to respond.
• ✔ A variety of communication-related DTCs stored in the vehicle’s memory.

The Direct-Fit Solution: Your 2003-2006 Escalade ESV BCM

Don’t let a faulty module compromise your vehicle’s safety and comfort. This replacement BCM is pre-programmed to your vehicle’s specific VIN before shipping. This critical step ensures seamless integration with your Escalade’s existing systems, eliminating the need for expensive and time-consuming dealership programming. It’s a true plug-and-play solution designed to get you back on the road quickly.

Installation & Post-Install Procedures

Physical 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 one in. However, please be aware of potential post-installation steps:

• Airbag System Sync: If the airbag light remains on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is required. This syncs the new BCM with the airbag system and must be performed with a professional-grade diagnostic scan tool.
• Brake Pedal Position Relearn: Some vehicles may require a brake pedal position sensor relearn to ensure proper brake light and traction control operation.
• No Core Charge: You are not required to return your old module. This saves you time and the hassle of a core return.
