Are you dealing with baffling electrical issues in your Chevrolet Express Van, Silverado, or GMC Sierra? When power windows, door locks, interior lights, or the HVAC system start acting erratically, the culprit is often a failing Body Control Module (BCM). This module is the central nervous system for your vehicle’s body electronics. This OEM-quality BCM, part number 15136225, is the definitive solution, arriving expertly programmed to your vehicle’s VIN for a true plug-and-play repair.

Common Symptoms of a Failing BCM:

- ✔ HVAC blower motor or climate controls not working correctly.
- ✔ Airbag warning light illuminated on the dash, often with a B1001 DTC.
- ✔ Erratic behavior from interior or exterior lights (flickering, staying on, or not turning on).
- ✔ Security system malfunctions, causing no-start or key recognition problems.
- ✔ False warnings on the driver information center (DIC).
Installation and Post-Install Considerations for your 2004-2007 Express 3500 BCM
Installation is straightforward for the DIYer or professional technician. The BCM is typically located under the steering column or behind the center dash panel. Disconnecting the battery before starting is recommended. Once installed, most vehicles will be fully functional. However, in some cases, additional steps may be needed:
- Airbag System Sync: If the airbag light remains on, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional scan tool to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration to ensure correct brake light and traction control operation.
This part is a direct replacement for multiple part numbers, including 15116066, 15136225, 10383536, 15198116, and others. It fits a wide range of vehicles like the Chevrolet Avalanche, Suburban, Tahoe; GMC Yukon, Sierra, Savana; Cadillac Escalade; and Hummer H2. Best of all, there is no core charge, so you can keep your old part.
Frequently Asked Questions
Will this BCM be programmed for my specific vehicle?
Yes. We require your vehicle’s VIN at checkout to program the module with the correct software and settings for your specific model and options, ensuring a plug-and-play installation.
What does a Body Control Module do?
The BCM is a computer that controls and monitors many of your vehicle’s non-engine related functions, such as power windows, locks, lights, wipers, HVAC system, and the security system.
Where is the BCM located on my 2005 Express Van?
On the 2004-2007 Express and Savana vans, the BCM is typically found in the center of the dash, often accessible by removing a lower dash panel. On most compatible trucks and SUVs, it is located under the steering column.
What if the airbag light is on after I install this 2004-2007 Express 3500 BCM?
If the airbag light is on, it means the new BCM needs to be synchronized with the vehicle’s Sensing and Diagnostic Module (SDM). This requires a ‘Setup SDM Primary Key in BCM’ procedure, which must be done with a professional-grade diagnostic tool.
Is there a core charge for this part?
No, there is no core charge. You are not required to send your old, faulty module back to us, saving you time and money on return shipping.
