Common Issues & How This Fixes Them

Owners of the 2010 Chevrolet Avalanche 1500 often face BCM-related headaches that disrupt everyday use. For instance, erratic door locks or non-responsive power windows can point to internal module corrosion, especially after exposure to moisture during off-road adventures. This leads to frustrating scenarios where you can’t secure your truck or adjust windows on the fly. Another frequent problem is interior lights staying on or flickering, draining the battery overnight—often tied to faulty relay controls within the BCM. In my experience, these stem from voltage spikes or age-related wear, triggering DTCs like B1325 for battery voltage issues. Replacing with this programmed 25826125 module resolves them by recalibrating the system to factory specs. Consider a case where a client towed a trailer and lost trailer brake lights; a quick BCM swap fixed the communication loss, preventing safety hazards. Additionally, anti-theft system malfunctions might cause no-start conditions, but this unit’s updated firmware clears those efficiently. By addressing root causes like poor connections or software glitches, it not only fixes symptoms but prevents recurrences, saving you from repeated shop visits. Always check for loose harnesses during diagnosis to pinpoint if the BCM is indeed the culprit.

Easy Installation Guide

1. Provide your VIN after purchase so we can program the BCM with the latest GM updates tailored to your 2010 Avalanche 1500.
