2004 – 2007 GMC SAVANA 2500 Body Control Module (BCM) 15198116 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com
Have you ever been stuck in your 2004-2007 GMC Savana 2500 van during a busy workday, only to find the door locks refusing to respond or the interior lights flickering erratically? These frustrating electrical glitches often stem from a failing body control module, disrupting everything from HVAC operation to security features in your reliable workhorse. As a seasoned mechanic who’s diagnosed countless vans like yours, I’ve seen how moisture from rainy deliveries or rough commercial use can corrode BCM connections, triggering DTCs and no-start headaches. The solution? Our OEM-spec GM 15198116 BCM, pre-programmed to your exact VIN for seamless integration. This plug-and-play unit restores smooth control over lights, windows, locks, wipers, and more, compatible with Savana 2500 models equipped with the commercial tradesman package (opt PRP). Interchangeable with numbers like 15198116, 15116066, and others, it clears persistent codes like B1001 without dealership visits. Beyond basic fixes, it enhances overall electrical stability, preventing cascading failures that could sideline your van during peak seasons.

Common Issues & How This Fixes Them
In my years working on GMC vans, I’ve encountered owners of 2004-2007 Savana 2500 models battling erratic HVAC blower speeds, especially in humid conditions that accelerate BCM wear. This often leads to loss of climate control, where the module fails to relay signals properly, causing intermittent operation or complete shutdowns—think sweating through a summer delivery without AC. Another frequent culprit is the airbag warning light illuminating with codes like B1001, triggered by faulty internal circuits that miscommunicate with the supplemental restraint system. Electrical gremlins, such as power windows that won’t budge or door locks that jam, usually point to degraded BCM relays from voltage spikes or age-related degradation. Security malfunctions can even result in no-start scenarios, where the anti-theft system locks out the engine due to communication breakdowns. Grounding issues exacerbate these, creating a web of DTCs that scanners flag relentlessly. Replacing with our pre-programmed 15198116 BCM addresses these root causes by recalibrating the network, clearing codes, and restoring reliable signal flow. For instance, one client with a tradesman-equipped Savana reported immediate resolution of wiper failures after install, avoiding costly downtime. This fix not only eliminates symptoms but also prevents escalation, like battery drain from constant short circuits, ensuring your van stays road-ready.
Easy Installation Guide
- Provide your vehicle’s VIN during purchase to ensure the BCM is pre-programmed accurately for your 2004-2007 Savana 2500.
- Disconnect the battery negative terminal to safely power down the system and reset any stored codes before starting.
- Locate the BCM in the center dash area, remove the old unit by unplugging connectors and mounting screws—usually a quick 5-minute process.
- Install the new module, reconnect everything, and reconnect the battery to initialize.
- If a no-start occurs post-install, perform a simple theft relearn: Insert key, turn to ON for 10 minutes, off for 30 seconds, repeat three times.
- Use a diagnostic scanner to perform the ‘Setup SDM Primary Key in BCM’ for airbag light reset and check for brake pedal recalibration if braking feels off—consult your manual for model specifics.
