2007 – 2011 Chevrolet Avalanche 1500 Body Control Module (BCM) 15943678 – 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 the HVAC blower acting up unpredictably? As a seasoned mechanic who’s fixed countless GM trucks, I’ve seen how a failing body control module can turn a reliable hauler into a frustrating puzzle. Questions like “why is my Avalanche’s airbag light on with DTC B1001?” or “how to fix intermittent door locks in a 2007 Avalanche 1500?” often point straight to the BCM. This pre-programmed GM BCM, interchangeable with 15943678 and others like 25844480 or 25835966, steps in as the straightforward solution. It restores control over lights, locks, wipers, security, and climate systems in your Avalanche, plus fits models like Silverado, Tahoe, Yukon, Sierra, Suburban, and Escalade from 2007-2013. With VIN-specific programming, it plugs right in, eliminating dealership visits and resolving those nagging electrical gremlins for smoother daily drives or off-road adventures.

Common Issues & How This Fixes Them

In my years diagnosing GM vehicles, BCM failures in the 2007-2011 Avalanche 1500 often stem from moisture ingress, voltage spikes, or worn internal circuits—common in trucks exposed to harsh weather or heavy towing. One frequent headache is erratic HVAC operation, where the blower cuts out mid-drive, leaving you sweating or freezing; this happens when the module loses communication with climate controls. Replacing with this VIN-programmed BCM reestablishes seamless signal flow, ensuring consistent airflow and temperature regulation. Another issue? The dreaded airbag warning light triggering DTC B1001, often tied to a mismatched or faulty module disrupting the supplemental restraint system. This fix clears those codes by syncing perfectly with your vehicle’s network, enhancing safety without ongoing scans. Electrical glitches like dead power windows or unresponsive door locks trace back to BCM relay failures, causing frustration during quick stops or loading gear. Security system woes, including false alarms or engine stalling from grounding faults, also resolve here, as the module’s robust design prevents misfires and improves anti-theft reliability. Beyond basics, consider how corrosion on connectors exacerbates these—always inspect during swaps to avoid repeats. In real scenarios, like a fleet owner with multiple Avalanches facing intermittent lights during night hauls, this BCM restored full functionality, cutting downtime and repair costs significantly.

4. After installation, if the airbag light stays on (like with DTC B1001), use a diagnostic tool to perform the ‘Setup SDM Primary Key in BCM’ procedure under the special functions menu.
5. Check for brake pedal recalibration needs—some models require this to maintain braking efficiency; consult your manual or a tech if unsure.
6. For theft relearn, only if a no-start issue arises: Insert key, turn to ON for 10 minutes, off for 5 seconds, repeat three times—simple key cycles often do the trick without tools.
