Experiencing Bizarre Electrical Issues in Your GMC Yukon?
If your 2003-2006 GMC Yukon is suffering from strange and frustrating electrical problems, a failing Body Control Module (BCM) is the most likely cause. The BCM acts as the central command center for your vehicle’s body electronics. When it begins to fail, it can create a cascade of issues that are difficult to diagnose, from flickering lights to a vehicle that won’t start. This OEM-quality replacement BCM, part number 15194170, is the definitive solution to restore your truck’s proper function and reliability.
Why Choose Our Pre-Programmed 2003-2006 Yukon BCM?

We pre-program this BCM to your vehicle’s specific VIN before shipping, ensuring it works correctly right out of the box. This plug-and-play solution saves you time, money, and the headache of scheduling a service appointment. Simply install it, and you’re back on the road.
Common Symptoms of a Failing BCM:
- ✔ Power windows, door locks, or mirrors not working or acting erratically.
- ✔ Interior or exterior lights staying on, flickering, or not turning on at all.
- ✔ HVAC and climate control functions failing or operating intermittently.
- ✔ Airbag warning light illuminated on the dash, often with a B1001 code.
- ✔ Vehicle security system malfunctioning, leading to a no-start condition.
- ✔ Inaccurate fuel gauge readings or other instrument cluster glitches.
Installation and Post-Install Considerations
Installation is straightforward for the average DIYer. The BCM is typically located under the driver’s side dashboard, near the steering column. Disconnecting the battery before you begin is recommended. While our programming handles the primary functions, some vehicles may require a ‘Setup SDM Primary Key in BCM’ procedure with a professional scan tool if the airbag light remains on after installation. This syncs the new BCM with the airbag system. This genuine replacement 2003-2006 Yukon BCM is your direct path to resolving persistent electrical faults.
