Restore Full Electrical Function to Your GM Vehicle
Are you battling frustrating electrical problems in your Cadillac Escalade, Chevy Silverado, or GMC Sierra? Flickering lights, unresponsive power windows, a malfunctioning HVAC system, or a persistent airbag light are common signs of a failing Body Control Module (BCM). The BCM acts as the central nervous system for your vehicle’s body electronics, and when it fails, it can cause a wide range of confusing and disruptive issues. This OEM-quality replacement BCM, part number 15878753 (interchangeable with 25844480 and others), is the definitive solution to restore your vehicle’s performance and reliability.
Symptoms of a Failing BCM
- ✔ Unresponsive or erratic power windows, door locks, or interior lights.
- ✔ HVAC blower motor or climate controls not working correctly.
- ✔ Illuminated airbag warning light, often with Diagnostic Trouble Code (DTC) B1001.
- ✔ Vehicle security system faults, leading to no-start or stalling conditions.
- ✔ Wipers behaving erratically or not working at all.
- ✔ A variety of communication codes stored in the vehicle’s diagnostic system.
Your Pre-Programmed Escalade Body Control Module Solution
Forget expensive dealership visits and programming fees. We provide a hassle-free solution by programming this Escalade Body Control Module to your vehicle’s specific Vehicle Identification Number (VIN) before it ships. This ensures that the module is loaded with the latest GM software updates for your exact model, making installation a true plug-and-play process. It arrives ready to be installed, immediately integrating with your vehicle’s existing systems to restore functionality and clear common fault codes right out of the box.
Installation and Post-Install Considerations
Located under the driver’s side dashboard, the BCM is typically straightforward to access and replace, often taking just a few minutes. However, please be aware of a few model-specific procedures that may be necessary after installation:
- Airbag System Sync: If the airbag warning light remains on after installation, a technician will need to perform the “Setup SDM Primary Key in BCM” procedure using a professional-grade scan tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration to ensure proper operation of the brake lights and traction control system.
This part requires no core charge, so you can keep your old module without any hassle. By addressing the root cause of your vehicle’s electrical issues with a reliable, pre-programmed BCM, you can drive with confidence knowing your lights, locks, and safety systems are working as the factory intended.
Frequently Asked Questions
What does a Body Control Module do in my Escalade?
The BCM is a computer that controls a wide range of non-engine related functions in your vehicle. This includes the power windows, power mirrors, air conditioning, interior and exterior lighting, power locks, and the security system.
Is this BCM really plug-and-play?
Yes, it is. We program the module to your vehicle’s VIN before shipping. This means it arrives ready for installation without the need for additional programming from a dealership, saving you time and money.
Why is my airbag light still on after installing the new BCM?
This is typically due to the new BCM needing to be electronically introduced to the vehicle’s Sensing and Diagnostic Module (SDM). A technician must perform the ‘Setup SDM Primary Key in BCM’ procedure with a compatible scan tool to clear the light.
Do I need to send my old part back?
No, there is no core charge for this part. You can keep or dispose of your original module without any additional fees or requirements.
Will this part fit my 2008 GMC Sierra if the title says Escalade?
Yes, this BCM fits a wide range of 2007-2013 GM trucks and SUVs, including the GMC Sierra, Chevrolet Silverado, Tahoe, and Suburban. Always verify the part number or use our fitment tool to confirm compatibility with your specific vehicle.
