2002 – 2005 – Body Control Module 15114669 Programmed To Your VIN VIN BCM

2002 – 2005 – BCM (BCM) 15114669 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com

Ever dealt with flickering interior lights or doors that won’t lock properly in your 2002-2005 Chevrolet Trailblazer, leaving you frustrated during a rainy drive home? Or maybe you’ve asked yourself, “Why is my GMC Envoy’s power windows acting up without warning?” These glitches often trace back to a faulty Body Control Module (BCM), the central hub managing your SUV’s electrical systems. Our pre-programmed BCM, featuring part number 15114669, steps in as the reliable fix, compatible with alternatives like 15122670, 15065293, 15191621, and 9352135. Tailored specifically to GM vehicles from this era, it arrives flashed with the latest GM updates using your VIN for seamless integration. This isn’t just a replacement—it’s a restoration of smooth operation, preventing those nagging electrical gremlins that disrupt daily drives. Drawing from over two decades in auto diagnostics, I’ve seen how a failing BCM can mimic bigger issues like battery drain or intermittent no-starts, but swapping in a properly programmed unit resolves them efficiently, saving you diagnostic headaches and shop bills.

• Incorporates the newest GM software updates, enhancing reliability in systems like lighting, locks, and windows for 2002-2005 models.
• Backed by a one-year warranty, giving you peace of mind against defects in these critical electrical controllers.
• No core charge hassle—keep your old part or recycle it, focusing solely on getting your vehicle back on the road.
• Supports a wide range of GM SUVs, from Trailblazer to Envoy, optimizing performance in vehicles without factory security systems.
• Expertly tested for durability, drawing on real-world scenarios where moisture or age degrades original modules, preventing future failures.

Common Issues & How This Fixes Them

In my years fixing GM trucks and SUVs, I’ve encountered countless owners battling BCM failures in 2002-2005 models like the Oldsmobile Bravada or Isuzu Ascender. One common symptom? Erratic dashboard warnings, such as an airbag light that stays illuminated, often due to corrupted module data from voltage spikes or wear. This can compromise safety systems, leading to failed inspections or anxiety on the highway. Our pre-programmed BCM resets these protocols, restoring accurate sensor communication. Another frequent headache involves malfunctioning accessories—think power seats that won’t adjust or wipers that activate randomly. These stem from the BCM’s role in relaying signals; a degraded unit disrupts the flow, but replacing it with our VIN-matched version recalibrates everything precisely. For instance, in a Rainier 04, I’ve seen how heat cycles erode connections, causing intermittent door lock failures. This fix not only resolves the immediate problem but also prevents cascading issues like drained batteries from constant relay chatter. If you’re noticing a “no communication” error on your scan tool, that’s a telltale sign—our module bridges that gap effectively. Beyond basics, consider how environmental factors like road salt in northern climates accelerate corrosion; opting for this updated BCM adds a layer of resilience, informed by patterns I’ve analyzed in shop repairs.

Easy Installation Guide

1. Provide your VIN immediately after purchase so we can program the BCM with GM’s latest updates before shipping.
2. Disconnect the battery to ensure safety, then locate the BCM typically on the front fuse box side or rear floor panel in models like the Envoy XUV.
3. Remove the old module by unplugging connectors and unbolting it—note any specific positioning for your vehicle, such as fuse box front in Saab 9-7X.
4. Install the new BCM, reconnecting all harnesses securely to avoid loose connections that could trigger codes.
5. Reconnect the battery and perform necessary relearns: If a no-start occurs, initiate theft deterrent relearn by turning the key to ON for 10 minutes, off for 5 seconds, and repeat three times.
6. For full functionality, use a diagnostic tool to run the ‘Setup SDM Primary Key in BCM’ procedure to reset the airbag warning light, and recalibrate the brake pedal if your model requires it for optimal safety.
