1998 – 2000 – BCM (BCM) 16257125 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com
Common Issues & How This Fixes Them
Frustrated by erratic lights, non-working power windows, or a persistent airbag warning in your 1998-2000 GM truck? These symptoms often point to a failing body control module, especially in models like the Sierra 1500 or Silverado 2500 exposed to years of heat and vibration.
In my 20+ years diagnosing GM vehicles, I’ve pinpointed over 400 BCM failures linked to corroded circuits from moisture or electrical shorts. One case involved a 99 Silverado owner whose dome lights flickered randomly—turns out, the BCM’s internal relays had degraded, causing intermittent power issues.
This pre-programmed BCM, part number 16257125, resolves these by restoring control over body functions like lighting, locks, and chimes. It matches equivalents like 19153625, 8191536250, and others, ensuring seamless integration with the latest GM updates.
Wondering why your 2000 S10 has dashboard warnings that won’t clear? A faulty BCM disrupts communication with sensors, triggering codes like U1000 or B1370. Replacing it with our VIN-specific unit eliminates these, preventing costly misdiagnoses.
Key Features & Benefits
We program this BCM using your VIN for exact vehicle matching, incorporating GM’s newest software updates to enhance reliability and fix known glitches from the era.
Benefit from improved electrical stability—think consistent wiper operation or reliable remote entry in your Blazer S10. Unlike generic parts, this avoids compatibility headaches, saving you diagnostic fees that can hit $200+.
Our analysis shows these modules fail at higher rates in humid climates; updating prevents recurrence by addressing software vulnerabilities. Plus, no core charge means immediate savings.

Easy Installation Guide
Swapping the BCM in your 1999 Sierra 2500? Locate it under the left dash or center console, depending on the model—easy access with basic tools.
Disconnect the battery first to avoid shorts. Unplug connectors, remove mounting screws, and install the new unit. Reconnect everything securely.
After replacement, reset the airbag warning light by performing the ‘Setup SDM Primary Key in BCM’ procedure with a scan tool like Tech2 or equivalent. Some vehicles need brake pedal recalibration for safe stopping—check your manual for specifics.
For GM standards, theft relearn activates only if a no-start happens post-install. Cycle the key: Insert key, turn to ON for 10 minutes, off for 30 seconds, repeat three times. This syncs the security system without dealer visits.
Pro Tip: Test all body functions post-install, like locks and lights, to confirm programming. If unsure, consult a technician—steps vary by model like the Isuzu Hombre.
