Restore Full Control Over Your Vehicle’s Electronics
If your 2003-2006 GMC Yukon XL 1500 is plagued by bizarre electrical issues—like malfunctioning power windows, flickering lights, or a dead HVAC system—a failing Body Control Module (BCM) is the most likely culprit. The BCM acts as the central nervous system for your vehicle’s body accessories, and when it fails, it can cause a cascade of frustrating problems. This OEM-quality replacement BCM, part number 15194170, is the definitive solution to restore your truck’s functionality and peace of mind.
Is Your Yukon XL 1500 BCM Failing?
A faulty BCM can manifest in numerous ways. Look for these common indicators that it’s time for a replacement:
- ✔ Unresponsive or erratic power windows, door locks, or interior lights.
- ✔ HVAC controls that don’t work or a blower motor that’s stuck on or off.
- ✔ The security system acting up, causing no-start or intermittent starting conditions.
- ✔ An airbag warning light on the dash, often accompanied by diagnostic trouble code B1001.
- ✔ Wipers that won’t turn on, off, or operate correctly.
- ✔ Multiple unrelated warning lights and communication error codes stored in the system.
The Plug-and-Play Solution for Your 2003-2006 Yukon XL 1500 BCM
The biggest hurdle in replacing a BCM is typically the need for expensive programming at a dealership. Our modules eliminate that step entirely. We pre-program this BCM to your vehicle’s specific VIN before shipping it to you. This ensures complete compatibility with all your vehicle’s existing options and systems. The result is a simple, plug-and-play installation that you can perform in your own driveway in minutes. No special tools, no dealer appointments, and no hidden fees.
Installation and Post-Install Notes
Installation is straightforward. The BCM is typically located under the driver’s side dashboard, near the steering column. Simply disconnect the negative battery terminal, unplug the electrical connectors from the old module, remove it, and install the new one. Reconnect the battery and you’re done. There is no core charge, so you don’t have to worry about the hassle of returning your old part.
In some cases, a post-installation procedure may be needed. If your airbag light remains on, a technician with a capable scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure. A brake pedal position sensor relearn may also be required on certain models to ensure proper brake light operation.
