Restore Full Functionality to Your GM Truck with a Pre-Programmed BCM
If you’re dealing with bizarre electrical problems in your 2003-2006 GMC Yukon XL 2500—like windows that won’t roll down, a security light that won’t turn off, or an HVAC system with a mind of its own—you’re not alone. The Body Control Module (BCM) is the central command for these systems, and when it fails, it can cause a cascade of frustrating issues. This direct-fit BCM, part number 15064149, is the reliable, straightforward solution. We pre-program it to your vehicle’s specific VIN, so it arrives ready for a plug-and-play installation, eliminating the need for an expensive trip to the dealership for programming.
Case Study: A Tricky Diagnosis
I had a 2005 Sierra 2500 in the shop last month with a classic case of BCM failure. The customer had already replaced the battery, alternator, and checked all the grounds trying to solve a parasitic drain and flickering dash lights. The scan tool showed a dozen intermittent communication codes. After 20 years of wrenching on these trucks, I know these symptoms often point directly to a failing BCM. A failing internal processor was causing network noise. We swapped in one of our VIN-programmed modules, and within 10 minutes, every issue was resolved. This isn’t just a part replacement; it’s a permanent fix for those electrical gremlins.
Is Your Yukon Showing These Electrical Warning Signs?
A faulty BCM can manifest in numerous ways. If you’re experiencing any of the following, it’s a strong indicator that your module needs replacement. This 2003-2006 Yukon XL 2500 BCM is designed to resolve these exact problems.
- ✔ The security or anti-theft light stays on, causing a no-start condition.
- ✔ Power windows, door locks, or interior lights work intermittently or not at all.
- ✔ The HVAC blower motor is erratic, or the climate controls are unresponsive.
- ✔ Your scan tool shows communication DTCs, such as B1001, or codes related to body systems.
- ✔ The airbag warning light is illuminated on the dash.
- ✔ Headlights, tail lights, or wipers behave unpredictably.
A Straightforward Guide to BCM Installation
One of the best features of this module is its simple installation. You don’t need to be a master mechanic to get your truck back in order. Just follow these steps.
- Safety First: Always disconnect the negative terminal on your vehicle’s battery before starting any electrical work. This prevents short circuits and helps reset the vehicle’s systems.
- Locate the BCM: On your Yukon XL 2500, the BCM is typically located under the driver’s side of the dashboard, near the steering column. It’s a black plastic box with several large electrical connectors.
- Swap the Module: Carefully unplug the color-coded connectors from the old BCM. They have release tabs that you’ll need to press. Once unplugged, remove the old module (it’s usually held by a few clips or small bolts) and install the new one in its place.
- Reconnect and Test: Plug the connectors firmly into your new BCM. Reconnect the battery terminal. Start the vehicle and test all the functions that were previously malfunctioning—windows, locks, lights, and HVAC.
Important Post-Installation Notes
While this 2003-2006 Yukon XL 2500 BCM is designed for plug-and-play use, some vehicles may require an additional step. If the airbag light remains on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system. In some cases, a Brake Pedal Position relearn may also be needed. We also offer a hassle-free purchasing experience with no core charge—you can keep your old part.

Frequently Asked Questions
What does ‘VIN Programmed’ mean for me?
It means we load your vehicle’s specific Vehicle Identification Number (VIN) and all related factory settings onto the module before we ship it. This ensures it communicates perfectly with your truck’s other computers, making installation as simple as plugging it in without needing a dealer.
Do I have to send my old BCM back?
No. There is no core charge for this part. You can keep your old module, which saves you the time and expense of return shipping.
What if the airbag light is on after I install it?
This can happen occasionally. It means the new BCM needs to be electronically introduced to the airbag system (SDM). A repair shop with a professional-grade scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to resolve this.
Is this something I can install myself at home?
Absolutely. For most DIYers with basic tools, this is a very straightforward job that takes less than 15 minutes. It’s typically located under the driver’s side dashboard and just requires swapping electrical connectors.
