Experiencing Bizarre Electrical Problems in Your GMC Yukon XL?
If your 2003-2006 GMC Yukon XL 1500 is suffering from frustrating electrical issues like flickering lights, malfunctioning power windows, or a dead HVAC system, a failing Body Control Module (BCM) is the most likely culprit. The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can cause a cascade of confusing and seemingly unrelated problems. This VIN-programmed BCM, part number 15137395, is the definitive solution to restore your truck’s full functionality and get you back on the road with confidence.
Diagnosing a Faulty 2003-2006 Yukon XL 1500 BCM
A bad BCM can manifest in numerous ways, often making diagnosis a challenge. It acts as the brain for many of the features you use every day. If you’re noticing any of the following, it’s a strong indicator that your BCM needs replacement.
Common Symptoms of BCM Failure:
- ✔ Power windows or door locks operating intermittently or not at all.
- ✔ HVAC and climate control functions are unresponsive or behave erratically.
- ✔ The security system malfunctions, causing no-start conditions or false alarms.
- ✔ Interior dome lights or exterior lights (headlights, taillights) stay on or won’t turn on.
- ✔ The airbag warning light is illuminated on the dash, often with a B1001 diagnostic trouble code (DTC).
- ✔ Wipers won’t function correctly or activate randomly.

Installation and Post-Install Considerations
Installation is a straightforward process for the average DIYer. The BCM is typically located under the driver’s side dashboard, near the steering column. Simply disconnect the old module’s electrical connectors and swap in the new one. While our VIN programming handles the majority of the setup, some vehicles may require a couple of simple relearn procedures:
- Airbag System Sync: If the airbag light remains on after installation, a technician will need to use a professional scan tool to perform the “Setup SDM Primary Key in BCM” procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: In some cases, a brake pedal position sensor relearn may be needed to ensure proper brake light and traction control operation.
Best of all, there is no core charge. You can keep your old part without the hassle of shipping it back.
Frequently Asked Questions
What does a BCM do on a 2003-2006 Yukon XL 1500?
The Body Control Module (BCM) is a computer that manages and controls your vehicle’s non-engine-related electronics. This includes power windows, door locks, the security system, interior and exterior lighting, wipers, and the HVAC system.
Do I need to program this BCM?
No. This BCM comes pre-programmed to your vehicle’s VIN. Simply provide your VIN at checkout, and the module will arrive ready for a plug-and-play installation, with no dealership programming required.
Where is the BCM located on my Yukon?
On the 2003-2006 GMC Yukon XL 1500, the BCM is typically found under the driver’s side of the dashboard, attached to or near the steering column.
My airbag light is on after installing the new BCM. What should I do?
This is a common occurrence. The new BCM needs to be electronically introduced to the airbag system (SDM). A mechanic with a professional-grade scan tool will need to perform the “Setup SDM Primary Key in BCM” procedure to resolve this.
Is there a core charge for my old part?
No, there is absolutely no core charge. You can keep your old module, which saves you the time and expense of a return shipment.
Will this part fix my intermittent power window and HVAC issues?
Yes. Intermittent or total failure of the power windows, door locks, and HVAC controls are classic symptoms of a failing BCM. Replacing it with this quality part is the correct fix for these issues.
