2004 – 2005 – BCM (BCM) 15065293 – 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 2004 Chevy Trailblazer? As a seasoned mechanic who’s fixed countless GM SUVs, I’ve seen how a failing Body Control Module (BCM) can turn a reliable ride into a headache. Questions like “why won’t my 2005 GMC Envoy start intermittently” or “how to fix BCM issues in 2004 Oldsmobile Bravada without security system” often point to this critical component. Our pre-programmed BCM, part number 15065293 (compatible with 15122670, 15114669, 15191621, 9352135), arrives ready for your vehicle after you provide your VIN. It fits models like 2002-2005 Chevrolet Trailblazer, GMC Envoy, Isuzu Ascender, Oldsmobile Bravada, Buick Rainier, and Saab 9-7X—specifically those without security systems, mounted front by the fuse box or rear floor panel. This setup ensures seamless integration, restoring functions like lighting control and door locks with the latest GM updates for peak performance.

Key Features & Benefits

• Arrives fully programmed using your VIN, eliminating complex setup hassles and ensuring exact match to your GM SUV’s specifications.
• Includes a robust one-year warranty, giving you peace of mind against defects in these 2004-2005 era modules prone to electrical glitches.
• No core charge means you keep your old part without extra fees, ideal for DIY repairs on vehicles like the Trailblazer EXT or Envoy XL.
• Supports multiple interchangeable part numbers, broadening compatibility for models without security features to avoid mismatched installations.
• Enhances vehicle reliability by addressing common BCM failures, drawing from GM’s updated software to prevent recurring issues like faulty signals.
• Expert-backed design helps in quick diagnostics, saving time and money compared to dealer visits for similar 2002-2005 Isuzu Ascender problems.

Common Issues & How This Fixes Them

In my shop, I’ve diagnosed BCM troubles in plenty of 2003-2004 GMC Envoys where owners report non-responsive power accessories. A common culprit? Corrosion or internal circuit failures in the module, often triggered by moisture ingress near the fuse box side. This leads to symptoms like intermittent wiper operation or unexplained battery drain in your 2005 Buick Rainier.

Another frequent headache is erratic interior lighting or door lock malfunctions in 2004 Trailblazer models without security. Causes include voltage spikes or age-related wear, disrupting the BCM’s role in managing body electronics. Replacing with our VIN-matched unit resolves this by restoring stable communication pathways.

For 2005 Saab 9-7X owners, dashboard warnings might persist due to faulty BCM integration with other systems. Our pre-flashed module fixes this by incorporating GM’s newest updates, preventing error codes like those related to fuse box signals.

Don’t overlook no-start conditions in 2002-2005 Envoy XLs; while rare, they stem from BCM anti-theft mismatches. A simple key cycle relearn—turning the ignition on for 10 minutes, off for 30 seconds, repeat three times—often clears it if issues arise post-install. Through years of hands-on work, I’ve found that addressing these early avoids cascading problems, like compromised safety features in rainy conditions.

Easy Installation Guide

1. Provide your VIN after purchase so we can program the BCM with the latest GM software tailored to your vehicle.
2. Disconnect the battery to ensure safety, then locate the BCM—typically front by the fuse box or on the rear floor panel in models like Envoy XUV.
3. Remove the old module by unplugging connectors and unbolting it carefully to avoid damaging surrounding wiring.
4. Install the new BCM in the same position, reconnect all plugs securely, and reattach the battery.
5. Perform any necessary relearns: If no-start occurs, do the theft deterrent relearn with key cycles as noted. Also, reset the airbag warning light via the ‘Setup SDM Primary Key in BCM’ procedure using a diagnostic tool.
6. Some vehicles may need brake pedal recalibration for optimal safety—consult your manual or a technician for model-specific steps.
