Is Your GMC Safari Experiencing Strange Electrical Problems?
If your 2000 GMC Safari or a similar GM truck is acting possessed—with flickering lights, malfunctioning power windows and locks, or a security light that won’t turn off—a failing Body Control Module (BCM) is the most likely culprit. The BCM is the central command center for your vehicle’s body electronics. When it starts to fail, it can cause a cascade of frustrating and seemingly unrelated issues that can be difficult to diagnose. Don’t let a faulty module keep your reliable truck or van off the road. This is your direct-fit, plug-and-play solution.
We had a 1999 Silverado in the shop that the owner was about to give up on. The truck would crank but not start, and the security light was always on. He had already replaced the fuel pump and ignition switch based on advice from forums, but the problem persisted. After a quick scan, we saw communication codes pointing to the BCM. The BCM’s security circuit had failed, preventing it from sending the ‘all clear’ signal to the powertrain computer. We installed one of our VIN-programmed BCMs, and the truck fired up on the first try. It’s a classic case where the BCM mimics other, more common failures, leading to wasted time and money on unnecessary parts.
Common Symptoms of a Failing 2000 GMC Safari BCM
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Headlights, taillights, or interior lights behaving erratically (staying on or not turning on).
- ✔ The security or anti-theft light is illuminated on the dash, potentially causing a no-start condition.
- ✔ Horn honking unexpectedly or not working at all.
- ✔ Wipers operating on their own or not responding to the switch.
- ✔ False warnings on the instrument cluster, such as a ‘door ajar’ light.
- ✔ Diagnostic trouble codes related to communication loss with the BCM (U-codes).
The Simple, Reliable Solution: A VIN-Programmed BCM
Forget expensive dealership visits and the hassle of finding a shop that can program a new module. We handle the complex part for you. This Body Control Module is meticulously tested for full functionality and then programmed with the latest GM software updates specifically for your vehicle. All we need is your Vehicle Identification Number (VIN) during checkout. When the part arrives, it’s ready for a straightforward installation, restoring all the functions you’ve been missing.
This module is a direct replacement for a wide range of GM trucks and SUVs from this era. By providing your VIN, you ensure perfect compatibility and avoid the headaches of mismatched software. Plus, with our no-core-charge policy, you can keep your original module without the hassle of sending it back.
Installation and Post-Install Syncing
On the 2000 GMC Safari and Chevy Astro, the BCM is typically located on the left-hand (driver’s) side of the dashboard. For other models like the S10, Blazer, and Jimmy, it’s often found in the center dash area. Installation is generally straightforward, involving disconnecting the battery, removing a few dash panels for access, and swapping the electrical connectors. However, after installation, some vehicles may require one or two simple relearn procedures to ensure all systems communicate correctly.
Post-Installation Procedures:
- ✔ Airbag System Sync: If your airbag warning light is on after installing the new BCM, it means the BCM and the Sensing and Diagnostic Module (SDM) need to be synced. A professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ procedure. This is only necessary if the light appears.
- ✔ Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be needed. This ensures your brake lights and traction control system function as intended. This procedure can also be completed with a compatible diagnostic tool.
Disclaimer: Vehicle systems can vary. We always recommend consulting a factory service manual or a qualified technician for specific instructions related to your vehicle.

Frequently Asked Questions
Do I need to program this BCM?
No! This is the biggest benefit of our service. We program the module to the VIN you provide before we ship it. It arrives ready for installation, saving you a trip to the dealership.
What is a VIN and why do you need it?
The VIN is your vehicle’s unique 17-digit identification number. It allows us to load the exact software and settings your vehicle had when it left the factory, ensuring perfect compatibility with your specific options.
Will this fix my ‘Security’ light and no-start problem?
A faulty BCM is a very common cause of an illuminated security light and a crank-no-start condition on these GM vehicles. While we cannot guarantee a fix for every vehicle, if the BCM is the root cause, this pre-programmed module will resolve the issue.
Where is the BCM located on my truck?
On the 2000 GMC Safari and Chevy Astro, it’s typically behind the driver’s side of the dashboard. On S-series trucks and SUVs (S10, Blazer), it’s usually in the center dash area. A quick search for your specific model will provide exact location diagrams.
What if the airbag light comes on after I install it?
This indicates the BCM and the airbag module (SDM) need to be electronically ‘introduced’. A technician with a high-level scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to sync the systems and turn off the light.
