2003 – 2006 Chevrolet Avalanche 1500 Body Control Module (BCM) 15064149 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com
Ever dealt with erratic power windows or dashboard lights flickering unexpectedly in your 2003-2006 Chevrolet Avalanche 1500? You’re not alone—I’ve seen countless owners face these frustrations, especially after electrical glitches from worn modules. What if your key fob suddenly stops responding during a rainy commute, leaving you locked out? These are classic signs of a failing Body Control Module (BCM), and replacing it with our pre-programmed unit, part number 15064149, can restore seamless operation. This BCM comes flashed with the latest GM updates tailored to your VIN, ensuring compatibility across models like the Sierra 3500 Pickup, Silverado 1500, Escalade, and more—covering part numbers such as 10383536, 15116066, and beyond. Beyond just fixing symptoms, it clears persistent DTC codes related to body electronics, enhancing overall vehicle reliability for daily drives or heavy towing. In my two decades of diagnostics, I’ve found that a properly matched BCM not only resolves intermittent failures but also prevents cascading issues like drained batteries from faulty relay controls.

Common Issues & How This Fixes Them
In my shop experience, a faulty BCM in a 2003-2006 Chevrolet Avalanche 1500 often manifests as unresponsive door locks or erratic interior lighting, stemming from internal corrosion or software glitches after years of exposure to moisture. For instance, one client with a Sierra 2500 Pickup reported constant security system false alarms, disrupting their work hauls—turns out, degraded circuits were misreading inputs, triggering DTCs like U0140. Our pre-programmed BCM resolves this by recalibrating communication networks, effectively clearing those codes and restoring normal function. Another frequent headache? Intermittent wiper failures during storms, caused by BCM relay malfunctions; replacing it with this unit, matched to your VIN, ensures precise control and prevents safety risks on wet roads. I’ve also diagnosed cases where the module causes random no-start conditions due to anti-theft mismatches—our flashed version bypasses that, often without needing full relearns. Plus, for vans like the Savana 2500 with commercial packages, it fixes accessory power inconsistencies that hamper tradesman tools. By addressing these root causes, this BCM not only fixes immediate problems but also boosts long-term dependability, potentially avoiding costly tow bills.
Easy Installation Guide
- Provide your VIN after purchase so we can program the BCM with the latest GM updates before shipping—essential for exact matching to your 2003-2006 Avalanche 1500.
- Disconnect the battery to ensure safety, then locate the BCM under the steering column (or center dash in some vans like Express models).
- Remove the old unit by unplugging connectors and unbolting it—note any corrosion on pins, as cleaning them can prevent future issues.
- Install the new BCM, reconnect everything securely, and reconnect the battery to power up the system.
- Perform a theft deterrent relearn if a no-start occurs: Insert key, turn to ON for 10 minutes, off for 5 seconds, repeat three times—simple key cycles often suffice for GM standards.
- After installation, reset the airbag warning light by running the ‘Setup SDM Primary Key in BCM’ procedure with a diagnostic tool; some vehicles may need brake pedal recalibration for optimal safety—consult your manual or a tech if unsure.
