2002 – 2005 GM Various BCM (BCM) 15081796 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com
Ever dealt with erratic dashboard lights flickering on your 2002 GMC Sierra 3500, or wondered why your power windows suddenly refuse to budge in a 2003 Chevy Blazer? These frustrating symptoms often point to a failing Body Control Module (BCM), the central hub managing everything from interior lighting to door locks in your GM vehicle. As a seasoned mechanic who’s swapped out hundreds of these units, I’ve seen how a faulty BCM can turn a reliable truck into a headache on wheels. The good news? Our pre-programmed BCM, featuring part number 15081796, arrives ready to install, flashed with the latest GM updates using your VIN for seamless compatibility. It matches equivalents like 15063578, 15095334, 19208537, DKAK, and DPNU, covering models from the Chevy Astro to the GMC Yukon. This direct replacement restores smooth operation, preventing those random electrical glitches that leave you stranded or dealing with safety concerns.

Common Issues & How This Fixes Them
In my years fixing GM trucks, BCM failures in 2002-2005 models like the Chevy Silverado or GMC Safari often stem from corrosion, voltage spikes, or age-related wear. Take a scenario where your Tahoe’s headlights dim unexpectedly or the security system triggers false alarms—these trace back to the BCM’s role in relaying signals between components. Without a proper fix, you might face escalating problems, like non-responsive key fobs or even airbag system errors that compromise safety. Our pre-flashed BCM resolves this by recalibrating communications, eliminating those pesky DTCs (diagnostic trouble codes) such as P1626 or U1000 common in these years. For instance, if your S10 pickup shows erratic wiper behavior, it’s likely a BCM glitch from water intrusion; replacing it with our unit restores precise control, preventing further electrical shorts. Another frequent headache? Door locks cycling on their own in a Yukon XL—caused by degraded internal circuits. This module’s updated firmware tackles that head-on, offering long-term stability. Beyond basics, consider how heat buildup under the dash accelerates failure in vans like the Astro; our solution includes robust builds to withstand such conditions, extending lifespan and cutting downtime.
Easy Installation Guide
- Provide your VIN immediately after purchase so we can program the BCM with the latest GM updates tailored to your vehicle.
- Disconnect the battery to ensure safety and prevent electrical surges during the process.
- Locate the BCM—typically under the steering column in pickups like the Sierra 3500 or in the center dash for vans like the Astro—and remove the old unit by unplugging connectors and unbolting mounts.
- Install the new BCM securely, reconnecting all harnesses carefully to avoid pinched wires.
- Reconnect the battery and perform any necessary relearns: If a no-start condition occurs, cycle the key from off to on 3-5 times for theft system adaptation per GM guidelines—no special tools needed unless issues persist.
- Reset the airbag warning light by running the ‘Setup SDM Primary Key in BCM’ procedure with a diagnostic tool; also, recalibrate the brake pedal if your model requires it for optimal safety and performance—check your manual or consult a tech for specifics.
