Is your GM truck or SUV suffering from frustrating electrical problems?
If you’re dealing with flickering lights, unresponsive power windows, a malfunctioning security system, or erratic HVAC controls, a failing Body Control Module (BCM) is the likely culprit. The BCM is the central computer for your vehicle’s body electronics, and when it fails, it can cause a wide range of confusing and intermittent issues. This OEM-quality replacement BCM, part number 15064149, is the definitive solution for restoring full electrical functionality to your 2002-2007 GM vehicle, including the Chevrolet Silverado, GMC Sierra, Tahoe, Suburban, and Cadillac Escalade.
From the Diagnostic Bay
We had a 2005 Silverado 2500 in the shop where the owner had already replaced the blower motor resistor and the main HVAC control head, but the fan would still cut out randomly. He was convinced it was a wiring issue. After a quick scan, we saw communication loss codes pointing to the BCM. Instead of hours chasing wires, we installed a VIN-programmed BCM. The HVAC system, along with a quirky power lock issue he hadn’t even mentioned, was fixed in under 10 minutes. It’s a classic case of the central brain failing, not the individual components.
Common Symptoms of BCM Failure
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ HVAC blower motor or climate controls operating erratically.
- ✔ The security light stays on, or the vehicle won’t start (No-Crank).
- ✔ Interior or exterior lights not working correctly.
- ✔ An active airbag warning light, often with a B1001 diagnostic trouble code (DTC).
- ✔ False warnings on the instrument cluster.
Restoring Functionality with a new Yukon XL Body Control Module
Don’t let a faulty module keep your truck off the road or full of annoying glitches. This replacement BCM is engineered to meet or exceed original equipment standards for reliability and performance. The most significant benefit is our pre-programming service. We flash the module with your vehicle’s specific VIN and the latest GM software updates before it ships. This means no expensive trips to the dealership for programming—it’s a true plug-and-play solution that gets you back on the road fast.
Installation and Post-Install Notes
Installation is simple for the average DIYer. The BCM is typically located under the driver’s side dash, near the steering column. Disconnecting the battery for a few minutes before swapping the modules is recommended. While the unit is plug-and-play, some vehicles may require a ‘Setup SDM Primary Key in BCM’ procedure with a professional scan tool if the airbag light appears after installation. Additionally, a Brake Pedal Position relearn may be needed on certain models. This part requires no core return, so you can keep your old module without any hassle.
