2004 – 2007 GMC SAVANA 1500 BCM (BCM) 15116066 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com
Ever dealt with erratic power windows or dashboard lights flickering unpredictably in your 2004-2007 GMC Savana 1500 during a long delivery haul? These frustrations often stem from a failing Body Control Module (BCM), disrupting everything from interior lighting to security systems. As a seasoned mechanic who’s swapped out hundreds of these in GM vans, I’ve seen how a faulty BCM can turn a reliable workhorse into a headache, especially in rainy weather where moisture seeps in and shorts circuits. The good news? Our pre-programmed BCM, part number 15116066, arrives ready to install with the latest GM software updates tailored to your VIN. It matches a range of compatible numbers like 10383536, 15136225, and others, ensuring seamless fit for various GM models including Savana vans with the commercial tradesman package (opt PRP). This direct replacement clears persistent DTC codes, restores smooth electrical functions, and boosts overall vehicle reliability—think fewer no-start issues on cold mornings or improved towing stability for heavy loads.

Common Issues & How This Fixes Them
In my years fixing GM vehicles, BCM failures in the 2004-2007 GMC Savana 1500 often show up as mysterious electrical gremlins. For instance, you might notice the interior lights staying on indefinitely, draining the battery overnight—typically caused by corroded connectors or software glitches from age and exposure. This not only strands you but also risks safety during night shifts. Another common headache: malfunctioning power accessories, like windows that won’t roll down or locks that fail randomly, often linked to water intrusion in the center dash location. We’ve seen this escalate to DTC codes like U1000 or B1370, halting vehicle functions and triggering check engine lights. Replacing with our pre-programmed BCM resolves these by recalibrating the network, clearing those codes, and restoring communication between modules. Picture a fleet owner who swapped one in their Savana van; post-install, they reported smoother anti-theft responses and better fuel efficiency monitoring, cutting downtime significantly. If you’re asking, “Why does my Savana 1500 BCM cause no-start problems after rain?” it’s likely moisture-related shorts—our unit’s updated firmware prevents recurrence, enhancing towing reliability for heavy-duty use. For intermittent wiper failures, a fresh BCM ensures consistent control, vital for safe driving in variable weather.
Easy Installation Guide
- Gather your tools: You’ll need a socket set, trim removal tools, and your vehicle’s VIN—provide it to us post-purchase for precise programming before we ship.
- Disconnect the battery: Safety first—remove the negative terminal to avoid electrical shorts while accessing the BCM in the center dash area.
- Locate and remove the old BCM: It’s mounted in the center dash for Savana models with opt PRP; unplug connectors carefully and unbolt it from its position.
- Install the new BCM: Secure it in place, reconnect all wiring harnesses, and double-check for firm connections to prevent future issues.
- Reconnect the battery and perform relearns: Cycle the key 3-5 times (on for 10 seconds, off for 5) if a no-start occurs due to theft system—GM standards indicate this simple step often suffices without full reprogramming.
- Test systems: Start the engine, check lights, locks, and accessories; use a scan tool for any lingering codes.
