2003 – 2006 Cadillac ESCALADE Body Control Module (BCM) 15064149 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com
Ever dealt with erratic power windows in your 2003-2006 Cadillac Escalade during a rainy drive, leaving you frustrated and soaked? Or maybe you’ve asked yourself, “Why is my Escalade’s interior lighting malfunctioning and triggering dashboard warnings?” These are classic signs of a failing Body Control Module (BCM), the central hub managing everything from door locks to lighting systems in GM vehicles. Our pre-programmed BCM, part number 15064149, arrives ready to install, flashed with the latest GM updates using your VIN for seamless compatibility. It replaces a range of OEM numbers including 10383536, 15116066, 15136225, and more, ensuring it fits models like the Escalade ESV, EXT, and even cross-compatible with Sierra pickups or Yukon XLs from similar years. This isn’t just a swap—it’s a reliable solution that clears DTC codes like U0140 or B1370, restores smooth electrical operations, and boosts overall vehicle reliability, especially for luxury SUV owners tackling urban commutes or long hauls.

Common Issues & How This Fixes Them
In my two decades fixing GM vehicles, I’ve seen countless 2003-2006 Escalade owners pull into the shop with BCM woes. One common headache is intermittent door lock failures—imagine trying to secure your luxury SUV at night, only for the locks to click erratically due to corroded BCM circuits from moisture exposure. This stems from aging modules losing calibration, often throwing DTC codes like B2960 that disrupt communication with other systems. Replacing with our pre-flashed BCM restores precise control, ensuring locks engage reliably and improving security features. Another frequent problem hits the lighting: headlights or dome lights flickering, especially after bumps, caused by voltage regulation faults in the module. This not only drains the battery but poses safety risks on highways. Our unit, updated to GM specs, stabilizes power distribution, clears those pesky codes, and enhances towing reliability by maintaining consistent trailer light functions. Then there’s the no-start scenario from anti-theft glitches—I’ve advised owners who thought it was a dead battery, but it was the BCM failing to recognize the key. A quick replacement often resolves it without full reprogramming. For Escalade drivers in harsh climates, these fixes prevent breakdowns, saving on tow fees and downtime. Expert tip: Scan for codes first with an OBD-II tool to confirm BCM involvement before diving in.
Easy Installation Guide
- Provide your VIN after purchase so we can program the BCM with the latest GM updates tailored to your 2003-2006 Escalade.
- Disconnect the battery to ensure safety and prevent electrical surges during the swap—locate the BCM under the steering column in most models.
- Remove the old module by unplugging connectors and unscrewing mounts; compare part numbers to verify compatibility.
- Install the new BCM, reconnecting all harnesses securely to avoid loose connections that could trigger new codes.
- Reconnect the battery and perform any necessary relearns: If a no-start occurs due to theft system issues, cycle the key from off to on (without starting) 3-5 times, waiting 10 minutes between cycles for the system to reset.
- Address post-install steps like resetting the airbag warning light via the ‘Setup SDM Primary Key in BCM’ procedure with a diagnostic tool, and check for brake pedal recalibration to maintain optimal braking safety—consult your manual or a pro if unsure.
