2007 – 2011 Chevrolet Avalanche 1500 Body Control Module (BCM) 15263497 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com
Ever dealt with your 2007-2011 Chevrolet Avalanche 1500 suddenly losing power to the windows or lights flickering erratically during a rainy drive? As a seasoned mechanic who’s seen countless GM trucks roll into the shop with these glitches, I know how frustrating it can beโespecially when you’re hauling gear for a weekend adventure. Questions like “why is my Avalanche’s HVAC blower acting up intermittently?” or “how to fix airbag warning light in 2007 Avalanche 1500 BCM” often lead owners here. The culprit? A failing body control module. Swap it out with this OEM-spec GM BCM, interchangeable with 15263497 and others like 25844480 or 25835966, pre-programmed to your VIN for seamless fit in models from Chevrolet Avalanche 1500 to GMC Sierra and Cadillac Escalade. This unit restores control over lights, locks, wipers, and more, clearing pesky DTCs and boosting overall electrical stability. Drawing from years of diagnostics, I’ve watched this fix transform unreliable rides into dependable daily drivers, even enhancing security features for safer towing in tough conditions.
Common Issues & How This Fixes Them
In my experience troubleshooting GM vehicles like the Avalanche 1500, a faulty BCM often shows up as erratic HVAC operationโthink blower motors that cut out mid-commute, leaving you sweating in summer heat. This stems from degraded internal circuits failing to relay signals properly, triggering DTCs like B1001 for airbag warnings. Another headache? Non-responsive power windows or door locks, caused by corrosion or voltage spikes that disrupt the module’s command over body electronics. Security system glitches can lead to unexpected stalling or misfires, especially in older 2007-2011 models exposed to harsh weather. Grounding problems exacerbate these, creating intermittent failures that mimic bigger issues. Replacing with this pre-programmed BCM resolves them by recalibrating communications, clearing diagnostic trouble codes without dealership visits, and preventing future breakdowns. For instance, one client with a 2009 Avalanche reported constant light malfunctions during towing; post-install, it handled heavy loads reliably, improving electrical consistency and reducing repair downtime.

Easy Installation Guide
- Provide your vehicle’s VIN during purchase to ensure precise pre-programming tailored to your 2007-2011 Avalanche 1500.
- Locate the BCM under the steering columnโdisconnect the battery first for safety, then remove the old unit by unplugging connectors carefully.
- Install the new module in the same spot, reconnecting all harnesses securely to avoid grounding issues that could cause recurring DTCs.
- Reconnect the battery and perform a quick test of functions like lights and locks; if no-start occurs, initiate theft relearn by cycling the key from off to run (engine off) three times, waiting 10 minutes each cycle.
- For persistent airbag lights (e.g., DTC B1001), use a diagnostic scanner to run the ‘Setup SDM Primary Key in BCM’ procedure under special functions.
- Check if brake pedal recalibration is neededโsome models require it post-replacement for optimal safety; consult your manual or a tech if unsure.
