Restore Full Control Over Your Vehicle’s Electronics
Are you battling frustrating electrical problems in your 2003-2006 GMC Yukon XL 1500? A failing Body Control Module (BCM) is often the culprit behind a cascade of issues, from malfunctioning power windows and door locks to a dead HVAC system or even a no-start condition. This replacement BCM, corresponding to part number 10367690, is the definitive solution to restore your vehicle’s electronic systems to perfect working order. As the central command center for your truck’s body functions, a healthy BCM is crucial for everyday convenience and safety.
We make the repair process simple with our professional Cloning Service. Instead of sending you a generic module that requires expensive dealership programming, we transfer the essential data from your original BCM to this replacement unit. The result is a true plug-and-play component that is ready for installation right out of the box, preserving all your vehicle’s original settings and features. This service eliminates the need for costly diagnostic tools or a visit to the service center, saving you both time and money.
From the Diagnostic Bay: The Case of the Haunted Yukon
A customer brought in his ’05 Yukon XL, convinced it was possessed. The dome lights would flicker randomly, the radio would cut out, and the security light stayed on, occasionally preventing it from starting. He’d already replaced the battery and checked the main grounds. After hooking up my scanner, I saw a handful of communication loss codes (U-codes) pointing to the BCM. In my 20+ years of experience, I’ve seen hundreds of these GMT800 platform vehicles where the BCM’s internal circuit board develops micro-fractures, causing these exact intermittent, maddening symptoms. A new, properly cloned 2003-2006 Yukon XL BCM solved every single issue in under 10 minutes.
Is Your Yukon XL Showing These Common BCM Failure Signs?
- ✔ The security or anti-theft system acts up, causing intermittent no-start conditions.
- ✔ Power windows, door locks, or mirrors work sporadically or not at all.
- ✔ Interior or exterior lights flicker, stay on, or fail to turn on.
- ✔ The HVAC and climate control system is unresponsive, or the blower motor is stuck on one speed.
- ✔ The airbag light is illuminated on the dash, often with a DTC like B1001 (Option Configuration Error).
- ✔ Your scan tool shows various communication or body-related Diagnostic Trouble Codes (DTCs).
A Straightforward Guide to BCM Installation
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning any electrical work.
- ✔ Locate the BCM: On most 2003-2006 Yukon XL models, the BCM is located under the driver’s side of the dashboard, near the steering column. It’s a black plastic box with several large electrical connectors.
- ✔ Remove the Old Module: Carefully unplug the color-coded wiring harnesses. They have locking tabs that need to be depressed. Once unplugged, unclip or unbolt the module from its mounting bracket.
- ✔ Install the New Module: Seat your cloned replacement BCM into the mounting bracket and securely plug in all the wiring harnesses. You can’t mix them up, as they are uniquely shaped.
- ✔ Reconnect and Test: Reconnect the negative battery terminal. Start the vehicle and test all functions: lights, locks, windows, wipers, and HVAC to confirm the repair was successful.
Post-Installation Checks
While our cloning service makes this a plug-and-play repair, some GM vehicles may require a simple relearn procedure. If your airbag light remains on, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ function. In some cases, a Brake Pedal Position Relearn might also be necessary. We always include your original module with the return shipment, and there is never a core charge.
