1999 – 2000 GM BCM (BCM) 09366801 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com
Ever dealt with erratic dashboard lights flickering on your 1999 Silverado 1500, or wondered why your power windows and locks suddenly quit working in a 2000 GMC Sierra 1500 Pickup? As a seasoned mechanic who’s wrenched on countless GM trucks from that era, I’ve seen these symptoms point straight to a failing Body Control Module (BCM). It’s frustrating when your reliable ride starts acting up—maybe the interior lights won’t shut off, draining the battery overnight, or the security system locks you out. The good news? Our pre-programmed BCM, matching part number 09366801 and cross-compatible with 19153625, 8191536250, 16257125, 191583625, 8093668010, 8162571250, and 8191536250, arrives ready to install with the latest GM updates flashed via your VIN. This isn’t just a swap; it’s a precise fix that restores seamless control over body electronics, from door locks to lighting systems. In my experience, skipping the programming step leads to persistent codes—don’t risk it. By providing your VIN post-purchase, we ensure it syncs perfectly, often resolving issues that basic replacements can’t touch.

Common Issues & How This Fixes Them
When your BCM starts failing in a 1999-2000 GM vehicle, symptoms can mimic other problems, leading to wasted time and money. Take intermittent power door locks in a Blazer S10—often caused by degraded internal circuits from moisture or age, resulting in security glitches that leave you locked out. Or consider dashboard warning lights staying on in a Sierra 1500; this stems from faulty communication between the BCM and other modules, triggering false alarms. In my garage days, I’d diagnose these with a scan tool, revealing codes like B1485 or U1064 tied to BCM faults. Another common headache: malfunctioning interior lights in an Astro van, where the module fails to process door signals, causing battery drain. Our pre-programmed BCM addresses these root causes by restoring precise control signals, preventing cascading failures. For instance, in a 2000 Isuzu Hombre, replacing with this unit cleared persistent anti-theft issues without needing extra resets. Expert tip: Always check for corrosion on connectors first—cleaning them can extend life, but when that’s not enough, this module provides a reliable resolution, often fixing multiple symptoms at once for smoother operation.
Easy Installation Guide
- Provide your VIN immediately after purchase so we can program the BCM with the latest GM updates tailored to your vehicle.
- Disconnect the battery to ensure safety and prevent electrical shorts during the swap—locate the BCM typically under the left dash or center dash, depending on your model like the Safari or S10.
- Remove the old unit by unplugging connectors and unbolting it; inspect for any damage or loose wires that might have contributed to the failure.
- Install the new BCM in the same position, securely reconnecting all plugs—double-check for firm seating to avoid connection issues.
- Reconnect the battery and perform any necessary relearns: If a no-start condition occurs due to anti-theft, cycle the key from off to on (without starting) 10 times, waiting 10 minutes between cycles per GM standards.
- Test all functions like lights, locks, and windows; if issues persist, use a diagnostic tool for final calibration.
