Restore Full Control Over Your GM Truck or SUV
If your 2007-2011 GMC Yukon is experiencing a host of frustrating electrical issues—like the radio cutting out, the A/C blower motor working intermittently, or the power windows refusing to budge—the culprit is often a failing Body Control Module (BCM). As the central command center for your vehicle’s body electronics, a faulty BCM can cause widespread and unpredictable problems. This replacement BCM, part number 25790509, is the reliable, pre-programmed solution to get your vehicle’s comfort and convenience features working like new again.
We take the guesswork and high cost out of the repair by programming this module to your vehicle’s specific VIN before it ships. This means you can skip the expensive trip to the dealership for programming. For the DIY mechanic or professional shop, this is a direct-fit, plug-and-play fix that restores functionality right out of the box.
Case Study: A Tricky Diagnosis
I remember a 2008 Sierra that came into my shop with the strangest combination of symptoms: the driver’s side power window was dead, the anti-theft light would flash randomly causing a no-start, and the owner complained of an airbag light. A quick scan pulled a B1001 for the airbag system and a U0155 (Lost Communication with Instrument Panel). Before condemning the BCM, we checked the main ground block under the driver’s side A-pillar—a common trouble spot. The ground was solid. The issue was a classic internal failure in the 2007-2011 Yukon BCM. Swapping in a VIN-programmed module like this one cleared all communication codes and restored every function in under 10 minutes. The only follow-up was the SDM key relearn to clear the B1001, which is a simple procedure with a capable scan tool.
Is Your Truck Showing These Symptoms?
- âś” Your power door locks, windows, or interior lights are behaving erratically or have stopped working entirely.
- âś” The HVAC system is unresponsive, or the blower fan only works on certain speeds or not at all.
- âś” The security system is malfunctioning, leading to unexpected alarm triggers or no-start conditions.
- âś” An airbag warning light is illuminated on the dash, often with a Diagnostic Trouble Code (DTC) like B1001.
- âś” You’re experiencing strange electrical ‘gremlins’ that seem to have no other logical cause.
A Straightforward Guide to Installation
- âś” Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on electrical components.
- âś” Locate the BCM: On most compatible GM trucks and SUVs, the BCM is found under the driver’s side of the dashboard, near the steering column.
- âś” Remove the Old Module: Carefully unplug the electrical connectors. They have locking tabs that need to be depressed. Once disconnected, the module can be unclipped or unbolted from its bracket.
- âś” Install the New BCM: Connect the electrical harnesses to your new, pre-programmed module. Ensure they click securely into place. Mount the BCM back onto its bracket.
- ✔ Reconnect and Test: Reconnect the negative battery terminal. Start the vehicle and test all body functions—lights, wipers, locks, windows, and HVAC—to confirm the repair.
Post-Installation Note: In some cases, particularly if you had an active airbag code, the airbag light may remain on. This requires a ‘Setup SDM Primary Key in BCM’ procedure using a bi-directional scan tool. This is not a defect but a necessary security handshake between the new BCM and the existing airbag system.

Frequently Asked Questions
What does this Body Control Module (BCM) actually do?
The BCM acts as the brain for your vehicle’s body electronics. It controls non-engine related functions like your power windows, door locks, interior and exterior lights, wipers, security system, and HVAC climate controls.
Is this part truly ‘plug-and-play’?
Yes. We program the module to your vehicle’s VIN before shipping, so it communicates correctly with your truck’s other systems upon installation. This eliminates the need for a dealership visit for expensive programming.
Why is my airbag light still on after installing the new BCM?
This is a normal security measure. The BCM and the airbag system (SDM) need to be electronically re-synced. This is done with a ‘Setup SDM Primary Key’ procedure using a professional-grade scan tool and is not a sign of a defective part.
Do I need to send my old part back?
No, there is no core charge for this module. You can keep or dispose of your old part, making the process hassle-free.
How can I be sure the BCM is my problem?
If you are experiencing multiple, unrelated electrical failures (like windows, radio, and locks all acting up), the BCM is a very likely cause. A full diagnostic scan can confirm by showing communication codes (U-codes) or specific BCM-related faults.
What does ‘VIN Programmed’ mean for me?
It means you save time and money. We load your vehicle’s specific software and settings onto the module before it leaves our facility, ensuring it works perfectly with the options your truck was built with from the factory.
