Restore Full Electrical Function to Your GM Truck or SUV
Are you battling frustrating electrical issues in your 2003-2006 GMC Yukon, Chevrolet Tahoe, or Silverado? Flickering lights, unresponsive power windows, a dead HVAC system, or a vehicle that refuses to start are all classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can cause a cascade of confusing problems. This OEM-quality BCM, part number 15137394, is the definitive solution, arriving pre-programmed to your vehicle’s VIN for a hassle-free, plug-and-play installation.
From the Diagnostic Bay
We had a 2005 Yukon XL come in with a laundry list of complaints: the radio would cut out, the driver’s side power window worked intermittently, and the security light was on, causing a no-start condition every few days. The owner had already replaced the battery and checked the grounds. After hooking up our scanner, we saw multiple communication loss codes with the BCM. Instead of a costly and time-consuming diagnostic rabbit hole, we installed a VIN-programmed BCM. In under 10 minutes, every single issue was resolved. The customer was thrilled to have their reliable family hauler back without a trip to the dealership.
Is Your GM Vehicle Showing These Symptoms?
- ✔ Power windows, door locks, or mirrors not working correctly.
- ✔ HVAC controls are unresponsive, or the blower motor operates erratically.
- ✔ The security system malfunctions, leading to a no-start condition.
- ✔ Interior or exterior lights flicker, stay on, or won’t turn on at all.
- ✔ The airbag warning light is illuminated, often with DTC B1001.
- ✔ A variety of seemingly unrelated diagnostic trouble codes (DTCs) are present.

Installation and Post-Install Notes
Installation is straightforward for the average DIYer. The BCM is typically located under the driver’s side dashboard, near the steering column. Simply disconnect the vehicle’s battery, remove the old module, plug in your new pre-programmed BCM, and reconnect the battery. No core charge means you can keep your old part without any hassle.
Important: In some cases, post-installation procedures may be necessary. If your airbag light remains on, a technician with a professional scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure. Additionally, a ‘Brake Pedal Position Relearn’ might be required on certain models to ensure proper brake light and traction control operation. Always consult a factory service manual for vehicle-specific instructions.
