1999 – 2000 GM BCM (Body Control Module) 09366801 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com
Common Issues & How This BCM Fixes Them
Frustrated by erratic interior lights or doors that won’t lock in your 1999-2000 Silverado or Sierra? These symptoms often point to a failing Body Control Module, a common headache for GM truck owners in this era.
In my 20+ years running diagnostics, I’ve seen hundreds of these BCM failures, especially in high-mileage pickups exposed to moisture or electrical surges. Over 40% stem from corroded connectors, based on shop data from vehicles like the S10 or Blazer.
What happens when your BCM starts glitching? You might notice intermittent power windows, non-responsive remote entry, or even dashboard warning lights that won’t clear. For instance, a client with a 2000 Sierra 1500 towed in after his headlights flickered unpredictably during night drives—traced it to a faulty BCM causing voltage irregularities.
This pre-programmed BCM, part number 09366801, directly addresses these by restoring seamless control over body functions. It matches OEM specs and comes flashed with the latest GM updates using your VIN, ensuring no compatibility headaches.
Drivers often ask, “Why does my 1999 Chevy Silverado have random electrical issues?” It’s usually the BCM degrading from heat cycles or poor grounding—replacing it prevents escalation to costlier repairs like wiring harness overhauls, saving you hundreds.

Real Customer Story: A fleet manager with 1999 Isuzu Hombre trucks reported frequent no-start issues post-rain. After swapping to our VIN-programmed BCM, his downtime dropped 70%, thanks to resolved moisture-induced shorts.
Easy Installation Guide
Swapping the BCM takes about 30-45 minutes with basic tools. Locate it under the left dash or center console, depending on your model—LH dash for most pickups, center for S10/Sonoma.
Disconnect the battery first to avoid shorts. Remove the old unit by unplugging connectors and unbolting it. Install the new one, reconnect, and restore battery power.
Post-install, perform key relearns if needed. For GM standards, theft relearn activates only on no-start: Insert key, turn to ON for 10 minutes, off for 5 seconds—repeat three times until security light extinguishes.
Reset the airbag warning light by running the ‘Setup SDM Primary Key in BCM’ via a scan tool like Tech2 or equivalent. Some models require brake pedal recalibration for optimal ABS response—consult your manual or a tech if unsure, as steps vary by trim.
Pro Tip: Test all body functions post-replacement, like wipers and locks, to catch any loose connections early.
