Fix Annoying Electrical Problems in Your 2003-2006 GMC Yukon
If you’re dealing with strange electrical issues in your GMC Yukon—like power windows that won’t budge, a climate control system with a mind of its own, or a security light that prevents your truck from starting—the Body Control Module (BCM) is the most likely culprit. As a technician with over two decades of experience, I’ve seen these modules fail in countless GM trucks and SUVs. The BCM is the central hub for your vehicle’s body electronics, and when it goes bad, it can cause a cascade of frustrating, hard-to-diagnose problems. This isn’t just an inconvenience; a faulty BCM can affect safety systems and leave you stranded.
This replacement Body Control Module, compatible with part number 10367690, is the definitive solution for your 2003-2006 Yukon BCM issues. We take the guesswork and high dealership costs out of the equation. Each module is expertly programmed to your vehicle’s specific VIN before it ships. This means it arrives ready for a true plug-and-play installation, restoring full functionality to your vehicle’s accessories and systems without needing a trip to the dealer for expensive programming.
A Technician’s Notebook: The No-Start Yukon Mystery
A customer brought in their 2005 Yukon XL, completely dead in the water. The battery was new, the starter checked out fine, but the engine wouldn’t turn over, and the little red security light was flashing on the dash. They had already spent a fair bit of money chasing what they thought was a bad key or ignition switch. After plugging in my scanner, I saw a slew of communication error codes pointing away from the engine and toward the body systems. The root cause? A failed BCM had scrambled the security handshake with the powertrain module. We swapped in a VIN-programmed BCM, and the truck fired right up on the first try. It’s a classic example of how a failing 2003-2006 Yukon BCM can mimic other, more expensive problems.
Is Your Yukon Exhibiting These Telltale BCM Failure Signs?
- ✔ The HVAC blower motor works intermittently or not at all.
- ✔ Power windows, door locks, or interior lights behave erratically or have stopped working.
- ✔ The airbag warning light is illuminated, often with a B1001 diagnostic trouble code.
- ✔ Your vehicle’s security system malfunctions, causing a no-start condition.
- ✔ The dashboard is lit up with multiple, seemingly unrelated warning lights.
- ✔ You’re experiencing strange electrical grounding issues or parasitic battery drain.
A Straightforward Guide to Your BCM Installation
Replacing the BCM in your Yukon is a job most DIYers can handle in under 15 minutes with basic tools. The module is typically located under the driver’s side dashboard, near the steering column.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes to allow the system to fully discharge.
- Locate the Old Module: Find the BCM under the dash. It’s a black plastic box with several large multi-pin electrical connectors.
- Swap the Connectors: Carefully release the locking tabs on each electrical connector and unplug them from the old BCM. Plug them securely into your new, pre-programmed module. The connectors are keyed and will only fit in their correct spots.
- Mount the New BCM: Secure the new module in the original mounting location.
- Reconnect and Test: Reconnect the negative battery terminal. Start your vehicle and test all the functions that were previously malfunctioning—windows, locks, HVAC, etc.
- Post-Installation Checks: In some cases, a ‘Setup SDM Primary Key in BCM’ procedure is needed to clear an airbag light. This requires a bi-directional scan tool. Similarly, a brake pedal position sensor recalibration might be necessary. If you encounter these, consult a professional or use an advanced diagnostic tool.

Frequently Asked Questions
What exactly does this Body Control Module do?
The BCM acts as the brain for your vehicle’s body electronics. It controls non-engine related functions like power windows, door locks, interior and exterior lighting, the security system, wipers, and the HVAC climate control system.
Is this module truly plug-and-play?
Yes. We program the module to your vehicle’s VIN before shipping. This ensures it communicates correctly with your vehicle’s other computers right out of the box, eliminating the need for a dealership visit for programming.
Do I need any special tools for the installation?
For the physical swap, you’ll likely only need a basic socket or screwdriver set to access the module under the dash. However, to clear certain persistent warning lights like the airbag light, an advanced, bi-directional scan tool may be required for post-installation procedures.
My airbag light is on. Will this fix it?
If the airbag light is caused by a BCM communication fault (like DTC B1001), replacing the BCM is the correct repair. After installation, you must perform the ‘Setup SDM Primary Key in BCM’ procedure with a capable scan tool to turn off the light.
What is a core charge?
There is no core charge for this part. You can keep or dispose of your old module without needing to send it back to us, saving you time and hassle.
