2007 – 2010 GMC SIERRA DENALI Body Control Module (BCM) 15901388 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com

Ever dealt with your 2007-2010 GMC Sierra Denali suddenly losing power to the windows or the HVAC blower acting up unpredictably? It’s frustrating when you’re hauling gear on a long drive, and the door locks fail or the security system triggers false alarms, leaving you stranded. As a seasoned auto repair pro who’s fixed countless GM trucks, I’ve seen how a failing body control module disrupts everything from lights to wipers. Enter the solution: our OEM-spec GM 15901388 BCM, pre-programmed to your exact VIN for seamless integration. This interchangeable unit (also matching 25844480 and others like 25835966, 15263363) restores control over essential electronics in models including Chevrolet Silverado, Tahoe, Suburban, and GMC Yukon variants. What sets it apart? It eliminates dealership visits by handling DTCs upfront, ensuring your Sierra Denali runs smoothly without ongoing glitches. Dive deeper, and you’ll appreciate how this fix prevents cascading electrical failures, saving you time and headaches on the road.

Common Issues & How This Fixes Them

In my years diagnosing GM vehicles like the 2007-2010 Sierra Denali, a faulty BCM often shows up as intermittent HVAC issues, where the blower motor cuts out or refuses to respond—usually tied to poor internal relays or corrosion from moisture exposure. Another red flag? The airbag warning light illuminating with codes like DTC B1001, stemming from communication breakdowns between modules. Electrical gremlins, such as power windows that won’t budge or door locks that jam, point to degraded circuits, while security malfunctions can cause no-starts or erratic stalling due to grounding faults. I’ve encountered trucks where wipers fail mid-storm or interior lights flicker randomly, all linked to BCM degradation from age or voltage spikes. Replacing with our VIN-programmed 15901388 resolves these by recalibrating body functions, clearing codes, and enhancing signal reliability. For instance, in one shop case, a Denali owner fixed persistent misfires by addressing BCM-induced grounding problems—post-install, everything stabilized. This isn’t just a swap; it’s a targeted repair that tackles root causes, reducing future diagnostics and keeping your truck dependable for heavy-duty tasks.

Easy Installation Guide

1. Provide your vehicle’s VIN during purchase to ensure precise programming—our team handles it with the latest GM updates.
2. Locate the BCM under the steering column; disconnect the battery first for safety to avoid electrical shorts.
3. Remove the old module by unplugging connectors and unbolting it—typically a 5-minute job with basic tools.
4. Install the new 15901388 BCM, reconnect everything, and restore battery power.
5. Perform post-install checks: If no-start occurs, do a theft relearn by cycling the key from off to on (without starting) 3 times, waiting 10 minutes each cycle until the security light clears.
6. For lingering airbag lights (like DTC B1001), use a diagnostic scanner to run the ‘Setup SDM Primary Key in BCM’ procedure; some models may need brake pedal recalibration for safety—consult your manual or a tech if unsure.
