Restore Full Electrical Function to Your GM Truck or SUV
Are you battling frustrating and unpredictable electrical problems in your late 90s or early 2000s GM vehicle? Flickering lights, malfunctioning power windows and locks, or a security system that prevents your truck from starting are common signs of a failing Body Control Module (BCM). The BCM acts as the central command center for your vehicle’s body electronics, and when it fails, it can create a cascade of confusing issues. This pre-programmed Body Control Module is the definitive solution, designed to restore your vehicle’s electronic systems to factory-perfect condition without a costly trip to the dealership.
From the Diagnostic Bay
We had a ’99 Silverado in the shop that was driving its owner crazy. The interior lights would randomly turn on while driving, the radio would shut off, and sometimes the truck just wouldn’t start, flashing the ‘Security’ light on the dash. The customer had already replaced the battery and checked the alternator. After hooking up our scanner, we saw multiple communication loss codes with the BCM. Instead of a complex and expensive rewiring job, we installed a VIN-programmed BCM. The truck fired up on the first try, and every single electrical gremlin was gone. It’s a classic failure on these models, and a correctly programmed module is the only reliable fix.
Is Your Vehicle Showing Signs of BCM Failure?
A faulty BCM can manifest in numerous ways, often mistaken for other issues. If your truck or SUV is experiencing any of the following, a failing BCM is the likely culprit:
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Interior dome lights or dashboard lights staying on or not working at all.
- ✔ The vehicle’s security system (Passlock) engaging randomly, causing a no-start condition.
- ✔ Erratic behavior from the radio or climate control systems.
- ✔ False warning lights on the instrument cluster.
- ✔ Inconsistent operation of windshield wipers.
- ✔ Communication errors when trying to read codes with a diagnostic scanner.

Simple Installation Process
This BCM is typically located under the driver’s or center dashboard. While installation is a plug-and-play process, please note the following potential post-installation procedures:
- Airbag System Sync: In some cases, the airbag warning light may illuminate after installation. A ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional-grade scan tool to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: A recalibration of the brake pedal position sensor might be necessary on certain models to ensure correct brake light and traction control operation.
We always recommend consulting a factory service manual or a qualified technician for specific instructions related to your vehicle.

Frequently Asked Questions
Why do you need my VIN?
Your vehicle’s VIN (Vehicle Identification Number) allows us to program the BCM with the exact software and settings for your specific model, year, and options. This makes the unit plug-and-play and ensures all features work correctly right out of the box.
Is this BCM difficult to install?
For someone with basic mechanical skills, the physical installation is straightforward. It involves locating the module under the dash, disconnecting the battery, and swapping the electrical connectors. However, some vehicles may require post-installation electronic procedures with a scan tool, as noted in the description.
Will this fix my ‘Security’ light and no-start problem?
Yes, a faulty BCM is the most common cause of Passlock security system issues in these GM trucks. A new, correctly programmed 1998-2000 GM Truck BCM will resolve these security-related starting problems.
What happens if the airbag light is on after I install it?
If the airbag light comes on, it means the new BCM needs to be electronically synchronized with the vehicle’s airbag module (SDM). This requires a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module.
