Solve Persistent Electrical Problems in Your GMC Yukon XL 2500
If you’re battling frustrating electrical issues in your 2003-2006 GMC Yukon XL 2500—like a dead HVAC system, malfunctioning power windows, or a security light that won’t turn off—you’ve likely pinpointed the culprit: a failing Body Control Module (BCM). As the central command for your truck’s body electronics, a faulty BCM can cause a cascade of problems that are difficult to diagnose. This replacement module, part number 10367690, is the definitive solution to restore full functionality and peace of mind.
We make this repair simple with our professional Cloning Service. Instead of paying for expensive dealership programming, you send us your original BCM. We expertly transfer all the critical vehicle-specific data to this replacement unit. When you receive it back, it’s a true plug-and-play installation, perfectly synced to your truck’s unique configuration. This process ensures all systems, including security and optional features, work correctly right out of the box.
A Technician’s Notebook
I remember a 2005 Yukon XL 2500 that came into the shop with a laundry list of bizarre symptoms. The radio would turn on and off by itself, the driver’s side window worked intermittently, and the A/C blower was completely dead. The owner had already replaced the blower motor resistor with no luck. After connecting my scanner, I saw a handful of communication codes pointing to the BCM. A failing BCM often creates these ‘ghost’ issues that seem unrelated. Once we installed a cloned replacement, every single problem vanished. It’s a testament to how critical this single component is to the vehicle’s entire network.
Is Your Yukon Exhibiting These Common BCM Failure Signs?
- ✔ The heating and air conditioning controls are unresponsive or the blower motor works sporadically.
- ✔ Power windows, door locks, or interior/exterior lights fail to operate correctly.
- ✔ The security or anti-theft system malfunctions, potentially causing a no-start condition.
- ✔ An airbag warning light is illuminated on the dash, often with a DTC like B1001.
- ✔ You’re experiencing strange electrical behavior, like the horn honking or wipers activating randomly.
- ✔ The instrument cluster displays erratic warnings or incorrect information.
Your Straightforward 5-Minute Installation Guide
Installing your cloned 2003-2006 Yukon XL 2500 BCM is a quick job for any DIYer or professional mechanic. No complex tools are needed.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery to prevent electrical shorts and allow the system to reset.
- Locate the BCM: On the Yukon XL 2500, the BCM is typically found under the driver’s side dashboard, near the steering column. It’s a small black box with several multi-pin connectors.
- Remove the Old Module: Carefully unplug the color-coded electrical connectors. They have release tabs that need to be pressed. Once unplugged, unclip or unbolt the module from its mounting bracket.
- Install the Cloned BCM: Mount the new module in the same location and securely plug in all the electrical connectors. You can’t mix them up, as they are keyed to fit only one way.
- Reconnect and Test: Reconnect the negative battery terminal. Start your vehicle and test all functions—lights, windows, locks, HVAC, and wipers—to confirm the repair was successful.
Post-Installation Note: In some cases, particularly if the airbag light was on, a professional scan tool may be needed to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the airbag system. A ‘Brake Pedal Position Relearn’ might also be required. These are simple procedures for any well-equipped shop. Our cloning service handles the security programming, which is the most critical part.

Frequently Asked Questions
Frequently Asked Questions
How does the cloning service work?
After you place your order, you’ll receive instructions to ship your original BCM to us. We then use specialized equipment to read the unique programming and security data from your module and write it directly onto the replacement unit. We ship both your original module and the ready-to-install replacement back to you.
What happens if I just install it without cloning?
The vehicle will not start. The BCM is a critical part of the vehicle’s anti-theft system (Passlock/Passkey). Without the correct data from your original module, it will not recognize your keys, and other features specific to your VIN will not work.
Where is the BCM located on my 2004 Yukon XL 2500?
The BCM is located under the driver’s side of the dashboard, usually attached to a bracket near the steering column. It’s a black plastic module with three or four large electrical connectors.
Will I need a scan tool after installation?
Typically, no special tools are needed as our cloning service handles all the programming. However, if your airbag light remains on, a ‘Setup SDM Primary Key’ procedure may be needed by a technician with a compatible scan tool. This is a simple sync procedure.
Is there a core charge or do I get my old part back?
There is absolutely no core charge. We require your original module for the cloning process, and it will always be returned to you along with your newly programmed replacement part.
