2002 – 2005 GM – BCM (BCM) 15095334 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com

Ever dealt with that frustrating moment when your 2002 Chevy Silverado’s door locks start acting up randomly, or the interior lights flicker without reason during a rainy drive home? As a seasoned mechanic who’s seen countless GM owners battle these electrical gremlins, I know how a faulty Body Control Module (BCM) can turn a reliable truck into a headache. Questions like “why won’t my 2003 GMC Sierra’s power windows respond?” or “how to fix intermittent dashboard warnings in a 2004 Chevy Astro?” often point straight to a failing BCM. This pre-programmed replacement, featuring part number 15095334 and compatibles like 15063578, 15081796, 19208537, DKAK, and DPNU, arrives flashed with the latest GM updates tailored to your VIN. It restores seamless control over body functions, clears nagging DTC codes, and enhances overall vehicle reliability—think smoother operation for daily commutes or heavy towing in tough weather.

Key Features & Benefits

• Arrives fully programmed using your VIN for exact match to your GM vehicle, ensuring plug-and-play readiness without dealership visits.
• Backed by a solid one-year warranty, giving you peace of mind against defects in these 2002-2005 models prone to electrical wear from age or moisture exposure.
• No core charge means you keep your old part or dispose of it hassle-free, saving time and extra costs during repairs.
• Optimizes systems like anti-theft and lighting, improving safety and preventing issues like failed remote entry that could strand you on long hauls.
• Incorporates newest GM software flashes to address known vulnerabilities, boosting longevity and reducing future diagnostic trouble codes for better fuel efficiency in trucks like the Sierra 3500.

Common Issues & How This Fixes Them

In my years fixing GM vehicles, I’ve encountered owners frustrated by symptoms tied to a worn BCM. For instance, erratic power door locks or windows in a 2002 Yukon often stem from corroded internal circuits, exacerbated by winter salt or high mileage, leading to security system malfunctions that trigger constant alarms. This replacement BCM resolves that by providing fresh, updated electronics that stabilize voltage and communication, effectively clearing related DTC codes like B2960 or U1000.

Another frequent complaint? Dashboard lights flashing or failing in 2003-2005 Blazer models, usually due to BCM failure from heat buildup under the dash. It disrupts everything from headlights to wipers, compromising night driving safety. Installing this pre-flashed unit restores proper relay control, preventing those intermittent blackouts and enhancing visibility during foggy commutes.

Don’t overlook starting problems in vehicles like the 2002 Silverado 1500, where a bad BCM might interfere with the immobilizer, causing no-start conditions. Our VIN-specific programming ensures compatibility, often eliminating the need for extensive relearns unless theft systems act up post-install.

I’ve advised many on overlooked causes like water intrusion in Safari vans, which shorts the BCM and affects HVAC controls. This part’s robust design mitigates that, offering reliable performance and potentially improving towing reliability by maintaining stable electrical loads under stress.

Easy Installation Guide

1. Provide your VIN after purchase so we can program the BCM with the latest GM updates before shipping—ensuring it matches your exact vehicle specs.
2. Disconnect the battery to avoid electrical shocks, then locate the BCM (typically under the steering column or center dash, depending on your model like Yukon or Astro).
3. Remove the old unit by unplugging connectors and unbolting it carefully—note any ID labels for reference.
4. Install the new BCM in the same position, reconnecting all harnesses securely to prevent loose connections that could cause new DTCs.
5. Reconnect the battery and perform any necessary relearns: If no-start occurs, cycle the key from off to run (without starting) 3-4 times for theft system reset, waiting 10 minutes each cycle per GM standards.
6. Test all body functions like locks, lights, and windows to confirm operation.
