Fix Your Yukon’s Electrical Headaches for Good
Are you chasing down bizarre electrical issues in your 2007-2011 GMC Yukon XL 2500? One day the power windows work, the next they don’t. The radio cuts out, the security light flashes for no reason, or the A/C blower has a mind of its own. These aren’t separate problems; they’re classic symptoms of a failing Body Control Module (BCM). As the electronic nerve center for your truck’s comfort and security features, a faulty BCM can cause chaos. This replacement Body Control Module, equivalent to GM part 25790508, is the definitive, hassle-free solution.
We take the guesswork and dealership costs out of the equation. Each module is expertly programmed to your vehicle’s specific VIN before it ships. This means no expensive trips to a mechanic for programming—it arrives ready for a true plug-and-play installation. Restore full, reliable function to your lights, locks, climate control, and more with a part engineered to meet or exceed original equipment standards. This is the most effective way to resolve persistent electrical gremlins and get your truck operating like new again.
Is Your Truck Showing These Telltale Signs?
- ✔️ The security or anti-theft light stays on, preventing the engine from starting.
- ✔️ Power windows, door locks, or mirrors operate intermittently or not at all.
- ✔️ HVAC controls are unresponsive, or the blower motor works sporadically.
- ✔️ An airbag warning light is illuminated, often with a Diagnostic Trouble Code (DTC) like B1001.
- ✔️ Headlights, taillights, or interior lights flicker or fail to turn on/off correctly.
- ✔️ The windshield wipers behave erratically or won’t park in the correct position.
A Straightforward Guide to Installation
Replacing your 2007-2011 Yukon XL 2500 BCM is a simple job that most DIYers can complete in under 15 minutes right in their driveway. The module is located under the driver’s side dashboard.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on electrical components.
- Locate the BCM: On most GM trucks of this era, the BCM is mounted to a metal bracket under the steering column, to the left of the brake pedal. It’s a black plastic box with several large multi-pin connectors.
- Disconnect and Remove: Carefully unplug the electrical connectors. They have locking tabs that need to be depressed. Once unplugged, the module can be unclipped or unbolted from its bracket.
- Install the New Module: Seat the new, pre-programmed BCM onto the bracket and securely plug in all the electrical connectors. You’ll hear a click as they lock into place.
- Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position and test all functions: windows, locks, lights, wipers, and HVAC to confirm the repair.
- Post-Installation Notes: In some cases, an airbag light may remain on. This requires a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ function. A Brake Pedal Position relearn may also be needed for certain models to ensure proper brake light and traction control operation.

Frequently Asked Questions
What does ‘VIN Programmed’ mean for me?
It means the module arrives ready to install right out of the box. We program it with your vehicle’s unique VIN and the latest GM software, so it communicates perfectly with your truck’s other systems without requiring a costly trip to the dealership for programming.
Do I need to send my old BCM back?
No, there is absolutely no core charge. You can keep your old part, so there’s no need to worry about return shipping or waiting for a core refund.
My airbag light came on after I installed the new BCM. Is it defective?
No, this is a normal security procedure on these GM vehicles. The new BCM needs to be electronically ‘introduced’ to the airbag system (SDM). This is done with a professional scan tool using the ‘Setup SDM Primary Key in BCM’ function and typically takes only a minute to complete.
Is this a difficult part for a DIYer to install?
Not at all. The installation is very straightforward and requires basic hand tools. It’s located under the driver’s side dash and simply unplugs and unclips. Most people can complete the swap in less than 15 minutes.
What is your warranty policy?
We stand behind our parts with a one-year warranty. This covers any defects in the module, giving you peace of mind with your purchase.
