Restore Full Electrical Function to Your GM Truck or SUV
Are you battling strange and frustrating electrical issues in your 2003-2006 GMC Yukon XL 1500? A failing Body Control Module (BCM) is often the culprit behind problems like flickering lights, unresponsive power windows and locks, or a malfunctioning security system. This genuine OEM-quality BCM, part number 15137394, is the definitive solution. It arrives expertly pre-programmed to your vehicle’s specific VIN, eliminating the need for expensive dealership visits and ensuring a seamless, plug-and-play installation.
From the Diagnostic Bay
We had a 2005 Silverado in the shop with a laundry list of bizarre symptoms: the dome light wouldn’t turn off, the driver’s side window worked intermittently, and the radio would randomly shut down. The owner had already replaced the battery and checked all the fuses. After connecting our scanner, we saw multiple communication loss codes pointing to the BCM. Instead of a complex wiring chase, we installed a VIN-programmed BCM like this one. In under 15 minutes, every single electrical gremlin was gone. It’s a common failure on these GM platforms, and a pre-programmed module is the fastest, most reliable fix.
Is Your Yukon XL Showing Signs of BCM Failure?
The BCM is the central command for your vehicle’s body electronics. When it fails, it can cause a wide range of problems. Look out for these common symptoms:
- ✔ Power windows, door locks, or mirrors not working correctly.
- ✔ Interior or exterior lights behaving erratically or not functioning at all.
- ✔ HVAC and climate control systems failing or blowing air incorrectly.
- ✔ An active airbag warning light, often with a B1001 diagnostic trouble code.
- ✔ Vehicle security system issues, including no-start or random alarm activation.
- ✔ Intermittent or complete loss of radio and instrument cluster functions.

Post-Installation Information
While installation is straightforward, some vehicles may require a simple follow-up procedure. If your airbag warning light remains on after installing the new 2003-2006 Yukon XL BCM, a technician will need to perform the “Setup SDM Primary Key in BCM” procedure with a compatible scan tool. This syncs the airbag system to the new module. In some cases, a Brake Pedal Position relearn may also be needed. Always consult a service manual for vehicle-specific instructions.
Frequently Asked Questions
What does this Body Control Module do?
The BCM acts as the central computer for your vehicle’s body electronics. It controls non-engine related functions like power windows, locks, lights, wipers, HVAC, and the security system.
Is this module ready to install out of the box?
Yes! This BCM is fully pre-programmed to your vehicle’s VIN before shipping. This makes it a true plug-and-play solution, requiring no further programming at a dealership.
What if my airbag light is on after installation?
This is a normal possibility. It means the new BCM needs to be electronically introduced to the airbag system (SDM). A technician can perform a quick “Setup SDM Primary Key” procedure with a professional scan tool to resolve this.
Do I need to return my old BCM?
No. There is no core charge or requirement to send your old part back to us. You can keep it or dispose of it at your convenience.
