2013 GMC SIERRA BCM (BCM) 15263497 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com
Ever dealt with your 2013 GMC Sierra’s power windows refusing to budge or the door locks acting up unpredictably, leaving you frustrated on a busy workday? What if your HVAC system suddenly quits, or an airbag light flashes with cryptic codes like DTC B1001, signaling deeper electrical woes? These headaches often trace back to a failing body control module, disrupting everything from lights to security features. Enter the GM 15263497 BCM, a precise replacement pre-programmed to your VIN for seamless fit in your Sierra 3500 or similar models. This OEM-spec unit restores control over interior/exterior lighting, wipers, power accessories, and more, covering 2007-2013 GM trucks like Chevrolet Silverado, Suburban, Tahoe, and GMC Yukon variants. Interchangeable with numbers like 25844480, 25835966, and others, it tackles those nagging issues head-on. As a seasoned mechanic who’s swapped dozens of these in heavy-duty pickups, I’ve seen how a quality BCM like this prevents cascading failures, saving you from costly tow bills and downtime.

Common Issues & How This Fixes Them
In my years diagnosing GM trucks, a faulty BCM in a 2013 GMC Sierra often shows up as erratic power window operation or non-responsive door locks, caused by internal corrosion or voltage spikes from worn wiring. This can escalate to security system glitches, where the vehicle stalls unexpectedly due to anti-theft miscommunications, stranding you mid-commute. Another red flag? Intermittent HVAC blower failures, stemming from the module’s inability to relay signals properly, especially in humid climates that accelerate component degradation. Airbag warnings with DTC B1001 frequently appear too, linked to communication breakdowns between the BCM and supplemental restraint systems. Replacing with the 15263497 unit fixes these by reestablishing stable electronic controls, preventing secondary issues like battery drain from constant short circuits. For instance, I once helped a Sierra owner whose wipers failed during a storm—turned out to be BCM grounding faults; a quick swap restored everything, highlighting how proactive replacement avoids bigger repairs. Always inspect harness connections first to rule out external causes.
Easy Installation Guide
- Provide your VIN during purchase to ensure pre-programming matches your 2013 GMC Sierra’s specs.
- Locate the BCM under the steering column—disconnect the battery first for safety to avoid electrical surges.
- Remove the old module by unplugging connectors and unbolting it; installation takes about 5 minutes with basic tools.
- After connecting the new 15263497 BCM, reconnect the battery and clear any initial codes using an OBD-II scanner.
- For persistent airbag lights (like DTC B1001), use a diagnostic tool to perform the ‘Setup SDM Primary Key in BCM’ procedure, resetting the warning effectively.
- Check for brake pedal recalibration if needed—some Sierras require this to optimize braking response; consult your manual or a tech if unsure, as steps vary by trim.
