Is your GMC Yukon XL 1500 suffering from strange electrical issues?
The Body Control Module, or BCM, is the central command center for your vehicle’s body electronics. When it begins to fail, it can cause a cascade of frustrating and seemingly unrelated problems, from malfunctioning lights and power windows to security system errors and even a no-start condition. If your Yukon is acting possessed, a faulty BCM is a likely culprit. This OEM-quality Body Control Module, part number 15137393, is the definitive solution to restore your vehicle’s full functionality.

Before condemning your BCM, take a moment to inspect your vehicle’s main battery terminals and primary chassis grounds. A loose, corroded, or weak ground connection can cause voltage drops that mimic the symptoms of a failing BCM. Verifying these connections first can save you time and money.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-functional HVAC controls and blower motor.
- ✔ Power windows, door locks, or interior lights stop working or behave erratically.
- ✔ The airbag warning light is illuminated on the dash, often with a B1001 diagnostic trouble code.
- ✔ Vehicle security system malfunctions, leading to alarm issues or a no-start situation.
- ✔ A variety of communication or body-related DTCs are stored in the vehicle’s computer.
- ✔ Wipers or exterior lights operate incorrectly or not at all.

Installation and Post-Install Considerations
Installation is straightforward for the DIY mechanic. The BCM is typically located under the driver’s side dashboard, near the steering column. Disconnecting the battery before you begin is recommended. While the module is plug-and-play for most 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. Additionally, a Brake Pedal Position Relearn may be needed on certain models. This unit is a direct replacement for multiple part numbers, including 15116066, 15136225, 15198116, and more, ensuring wide compatibility.
