2003 – 2006 Chevrolet Tahoe Body Control Module (BCM) 15137394 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com

Ever dealt with frustrating electrical glitches in your 2003-2006 Chevrolet Tahoe, like doors that won’t lock properly during a rainy drive or headlights flickering unexpectedly on a night road trip? You’re not alone—I’ve seen countless Tahoe owners pull into the shop with these symptoms, often tracing back to a failing Body Control Module (BCM). Questions like “why won’t my 2003 Tahoe power windows work intermittently?” or “how to resolve BCM-related DTC codes in a 2006 Tahoe?” flood forums, and the fix often boils down to replacing this critical component. Our pre-programmed BCM, part number 15137394, is flashed with the latest GM updates using your VIN for a seamless match. It replaces numbers like 10383536, 15116066, and others, ensuring compatibility across models such as the Sierra 2500 Pickup or Yukon XL 1500. This isn’t just a swap—it’s a restoration of reliable performance, clearing error codes and boosting overall vehicle electronics stability for safer, smoother drives.

Common Issues & How This Fixes Them

In my two decades fixing GM vehicles, BCM failures in 2003-2006 Tahoes often show up as erratic power accessories—think windows that roll down but not up, or malfunctioning keyless entry that leaves you locked out in the cold. These stem from internal circuit degradation, exacerbated by moisture exposure or voltage spikes, leading to DTC codes like U0140 or B1370 that disrupt daily driving. Another common headache is intermittent dome lights or alarm systems going haywire, which I’ve diagnosed in Tahoes used for family hauls or work duties, causing safety concerns during low-visibility conditions. Replacing with our VIN-matched BCM resolves these by restoring proper signal processing, effectively clearing codes and preventing recurrence. For instance, a client with a 2005 Tahoe towing a boat reported improved electrical stability post-install, avoiding breakdowns on long trips. Don’t overlook subtle signs like a non-responsive radio or erratic wipers; early replacement can save on broader repairs. This module also addresses theft deterrent issues, ensuring your vehicle starts reliably without unnecessary no-start scenarios.

Easy Installation Guide

1. Provide your VIN after purchase so we can program the BCM with the latest GM updates before shipping—ensuring it’s ready to install.
2. Locate the BCM under the steering column in your Tahoe (or center dash in some van models); disconnect the battery to avoid electrical shorts.
3. Remove the old unit by unplugging connectors and unbolting it—note any corrosion on pins, which could indicate underlying wiring problems to inspect.
4. Install the new BCM, reconnect everything securely, and reconnect the battery.
5. Perform post-install procedures: Use a diagnostic tool for the ‘Setup SDM Primary Key in BCM’ to reset the airbag warning light, and check if brake pedal recalibration is needed for optimal safety.
6. If a no-start occurs due to theft system, do a simple relearn: Insert key, turn to ON for 10 minutes, off for 5 seconds, repeat three times—consult your manual or a tech if variances apply.
