Restore Full Electrical Control to Your GM Truck or SUV
Are you battling frustrating electrical gremlins in your GMC Yukon, Chevy Silverado, or Cadillac Escalade? Intermittent wipers, flickering lights, unresponsive power windows, or a malfunctioning security system are common 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 and unpredictable problems. This genuine GM-quality Body Control Module, part number 25844480, is the definitive solution to restore your vehicle’s functionality and peace of mind.
From the Diagnostic Bay
We had a 2009 Silverado 1500 come in that was driving the owner crazy. The radio would turn on by itself, the door locks would cycle randomly, and the HVAC blower was completely dead. The owner had already replaced the blower motor resistor and the control head with no success. After a quick scan, we saw multiple communication loss codes pointing to the BCM. Instead of a complex wiring issue, the root cause was the central module itself. We installed a VIN-programmed BCM, and within 10 minutes, every single issue was resolved. It’s a reminder that sometimes the most complex-seeming electrical issues have a single, straightforward solution.
Is Your Yukon BCM Failing?
A faulty BCM can manifest in numerous ways. If you’re experiencing any of the following symptoms, it’s highly likely your Body Control Module is the culprit:
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ Interior or exterior lights staying on, flickering, or failing to activate.
- ✔ HVAC system problems, such as an inoperative blower fan or incorrect temperature control.
- ✔ An active airbag warning light, often accompanied by DTC B1001.
- ✔ Security system malfunctions, causing no-start conditions or false alarms.
- ✔ Erratic behavior from the windshield wipers or radio.
- ✔ A variety of seemingly unrelated diagnostic trouble codes (DTCs).
The Direct-Fit Solution for Your 2007-2011 Yukon Body Control Module
Don’t let a faulty module keep your truck off the road or stuck with annoying issues. Our BCMs offer a simple, effective repair. We pre-program each module to your vehicle’s specific VIN before shipping. This means no expensive trips to the dealership for programming are required. It arrives ready for a true plug-and-play installation, loaded with the latest GM software updates to ensure optimal performance and compatibility. This process resolves common DTCs and ensures all electronic features operate exactly as they did from the factory.
Installation and Post-Install Procedures
Replacing the BCM is a straightforward job for a DIYer or professional technician. The module is typically located under the driver’s side dash, near the steering column. The physical swap takes only a few minutes. However, be aware of potential post-installation steps:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a procedure called ‘Setup SDM Primary Key in BCM’ must be performed using a professional-grade scan tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be needed to ensure correct brake light and traction control operation.
This module is a direct replacement for a wide range of part numbers, including 25790508, 25835966, 15943678, 20939137, and 22860591. Restore your vehicle’s electrical systems with a reliable, pre-programmed 2007-2011 Yukon Body Control Module and get back on the road with confidence.
Frequently Asked Questions
What does a Body Control Module do?
The BCM acts as the central computer for your vehicle’s body electronics. It controls non-engine related functions like power windows, locks, lights, wipers, security system, and the HVAC system.
Is this BCM difficult to install?
The physical installation is very simple, usually taking less than 10 minutes. It’s located under the steering column and just requires unplugging the old one and plugging in the new one. Some post-installation electronic procedures may be necessary depending on your vehicle.
Will I need to take my truck to the dealership after installation?
No. This module comes pre-programmed to your vehicle’s VIN. This eliminates the need for dealership programming, saving you time and money.
What if my airbag light is on after installing the new BCM?
If the airbag light appears, you will need to perform the ‘Setup SDM Primary Key in BCM’ procedure with a professional scan tool. This is a simple sync process that a qualified mechanic can perform.
Is there a core charge for my old part?
No, there is no core charge. You can keep your old module without needing to send it back.
