Is Your GM Truck or Van Acting Possessed?
If you’re dealing with a frustrating storm of electrical gremlins in your 2003-2007 GM vehicle, you’re not alone. In my 20+ years as a technician, I’ve seen hundreds of these trucks and vans come into the shop with bizarre symptoms: power windows that won’t budge, interior lights that stay on, a security light that flashes constantly, or a radio that seems to have a mind of its own. More often than not, the culprit is a failing Body Control Module (BCM). This module is the central nervous system for your vehicle’s comfort and convenience features, and when it goes, it can make your reliable workhorse feel haunted.
From the Shop Floor: A Real-World Diagnosis
“Just last month, a customer brought in his ’05 Silverado 2500. The complaint was that the power door locks were firing randomly, even while driving down the road. He’d already replaced the switches, but the problem persisted. After a quick scan, we saw communication loss codes pointing to the BCM. A physical inspection revealed corrosion on one of the main connectors from a minor windshield leak over time. We replaced it with one of our VIN-programmed modules, and the truck was back to normal in under an hour. It’s a textbook failure for these vehicles.”

Easy Installation Process
- Safety First: Disconnect the negative terminal from your vehicle’s battery.
- Locate the BCM: On Silverado and Sierra pickups, it’s typically located under the driver’s side of the dashboard, near the steering column. On Express and Savana vans, it’s usually found behind the center dash panel.
- Disconnect & Remove: Carefully unplug the electrical connectors. They have locking tabs that need to be depressed. Once unplugged, remove any bolts or clips holding the old BCM in place.
- Install the New BCM: Mount your new, pre-programmed BCM and securely reconnect all the electrical connectors. You should hear a ‘click’ as they lock in.
- Reconnect Battery: Re-attach the negative battery terminal.
- Perform Final Procedures: Follow the critical post-installation steps outlined below.
IMPORTANT: Post-Installation Procedures Required
After installing your new 2003-2007 GM BCM, a couple of final steps are necessary to ensure all vehicle systems work together correctly. Failure to perform these steps can result in warning lights and improper system operation.
- Airbag System Reset: The ‘Setup SDM Primary Key in BCM’ procedure must be performed with a compatible high-level diagnostic scan tool. This re-establishes communication between the new BCM and the airbag system (SDM), which will turn off the airbag warning light.
- Brake Pedal Position (BPP) Sensor Calibration: Some vehicles may require the BPP sensor to be recalibrated. This ensures the brake lights and stability control systems receive the correct input from the brake pedal.
If you are not equipped to perform these procedures, we strongly recommend seeking assistance from a qualified professional technician.
