Restore Full Electrical Function to Your GM Truck or SUV
Are you battling frustrating and unpredictable electrical problems in your GMC Yukon XL 1500? One moment the power windows work, the next they don’t. The A/C blower motor has a mind of its own, and strange warning lights appear on your dash. These are classic signs of a failing Body Control Module (BCM), the central command center for your vehicle’s body electronics. A faulty BCM can disrupt everything from your interior lights and security system to your HVAC controls, making your vehicle unreliable and unsafe.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Erratic HVAC blower motor or climate control issues.
- ✔ Airbag warning light illuminated on the dash, often with DTC B1001.
- ✔ Security system malfunctions, causing no-start or stalling conditions.
- ✔ Headlights, taillights, or interior lights not working correctly.
- ✔ Windshield wipers behaving erratically or not working at all.
From the Diagnostic Bay
We once had a 2009 Sierra come in with classic BCM failure symptoms—flickering lights and a dead radio. The customer had already replaced the BCM from another supplier, but the problems persisted. A quick check with a multimeter revealed the real culprit: a corroded ground wire under the driver’s side A-pillar trim. Before condemning your BCM, always verify your main grounds are clean and tight. This simple check can save you time and money.

Frequently Asked Questions
Do I need to have this BCM programmed by a dealer?
No. We pre-program the module to your vehicle’s VIN before it ships. It arrives ready for a plug-and-play installation, saving you a trip to the dealership and expensive programming fees.
What happens if my airbag light is on after installation?
In some cases, the new BCM needs to be synced with the airbag system’s Sensing and Diagnostic Module (SDM). This requires a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure. This is a quick process for any qualified technician.
Where is the BCM located on my 2008 Yukon XL?
The Body Control Module is typically located under the driver’s side of the dashboard, near the steering column. Installation usually takes less than 15 minutes with basic hand tools.
Is there a core charge for this part?
No, there is no core charge. You can keep your old module without any obligation to return it, making the replacement process simple and hassle-free.
Will this fix a B1001 diagnostic trouble code?
Yes, a faulty BCM is a very common cause of a B1001 code. Replacing the module with our VIN-programmed unit will typically resolve this code, though the SDM key relearn procedure may be necessary to clear the airbag light.
