Is Your GM Vehicle Experiencing Bizarre Electrical Issues?
If your 2002-2005 GMC Safari, Chevy Astro, or other compatible GM truck or SUV is suffering from frustrating electrical gremlins, a failing Body Control Module (BCM) is the most likely culprit. The BCM acts as the central nervous system for your vehicle’s body electronics, controlling everything from your power windows and locks to the interior lights and security system. When it starts to fail, it can cause a wide range of confusing and intermittent problems.
This is a direct-fit replacement Body Control Module, part number 15063578. The best part? It arrives at your door fully programmed to your vehicle’s exact specifications. Simply provide us with your VIN during checkout, and our technicians will flash the module with the latest GM software updates.

Common Symptoms of a Failing BCM
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Erratic behavior from the radio or instrument cluster gauges.
- ✔ Interior or exterior lights staying on or not turning on at all.
- ✔ The security system engaging randomly or preventing the vehicle from starting.
- ✔ A ‘Service Vehicle Soon’ or other warning lights on the dash.
- ✔ Communication loss codes when scanned with a diagnostic tool.

Installation and Post-Install Procedures
Installation is straightforward for a DIY mechanic or any professional technician. After the new module is installed, one or two additional steps may be required:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a capable 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 operation.

Frequently Asked Questions
What does the Body Control Module do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine related electronic accessories, such as power windows, locks, lights, wipers, and the security system.
Do I need to have this module programmed?
No. We handle all the programming for you before we ship the part. Just provide your vehicle’s VIN at checkout, and it will arrive ready to install.
Where is the BCM located on a 2004 GMC Safari?
On the GMC Safari and Chevy Astro vans, the BCM is typically located behind the center of the dashboard. On trucks like the Silverado and Sierra, it’s usually found under the steering column.
What if my airbag light comes on after I install it?
This is normal on some vehicles. It simply means the new BCM needs to be electronically introduced to the airbag system. A technician with a professional-grade scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Is there a core charge for my old part?
No, there is no core charge. You can keep your original module without needing to send it back.
Will this fix my vehicle not starting?
If the no-start issue is caused by the factory security system (Passlock/VATS) which is controlled by the BCM, then yes, this programmed module will resolve that problem.
