1999 – 2000 – Body Control Module 9366801 Programmed To Your VIN

1999 – 2000 GM – Body Control Module (BCM) 9366801 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com

Ever dealt with erratic dashboard lights flickering on your 1999 GMC Sierra 1500 pickup, or wondered why your power windows suddenly refuse to budge in a 2000 Chevy Silverado? As a seasoned mechanic who’s wrenched on countless GM trucks from that era, I’ve seen these frustrations firsthand—often tracing back to a failing Body Control Module. Picture pulling into a job site only for your door locks to glitch, leaving you locked out in the rain. This pre-programmed BCM, part number 9366801, directly addresses those woes by restoring seamless control over your vehicle’s electrical systems. It matches OEM specs and comes flashed with the latest GM updates using your VIN for a perfect fit. Compatible with equivalents like 19153625, 8191536250, 16257125, 191583625, 8093668010, 8162571250, 8191536250, and 09366801, this module ensures no guesswork. Beyond basic replacement, it delivers peace of mind through expert calibration that prevents recurring faults, drawing from real-world diagnostics where outdated modules cause intermittent failures in high-mileage rigs.

Key Features & Benefits

• Pre-flashed with GM’s newest software updates via your VIN, ensuring instant compatibility and eliminating programming hassles right out of the box.
• Supports a wide array of 1998-2000 GM models, from S10 pickups to Sierra 2500 trucks, with precise fitment for center or left-hand dash locations.
• Backed by a one-year warranty, covering defects and giving you confidence in long-term reliability without extra costs like core charges.
• Optimizes electrical functions like lighting and security, reducing the risk of battery drain from faulty circuits—ideal for daily drivers facing harsh weather.
• Incorporates diagnostic-friendly design, making it easier to scan and clear codes related to body systems in older GM vehicles.
• Streamlines repairs by matching IDs like 16257125, so you avoid mismatched parts that could trigger persistent error lights.

Common Issues & How This Fixes Them

In my two decades fixing GM trucks, BCM failures often manifest as mysterious electrical gremlins. For instance, if your 1999 Chevy Silverado 1500 has non-responsive interior lights or erratic wiper operation, it could stem from corroded BCM circuits—common in vehicles exposed to moisture. This leads to frustrating downtime, like when accessories fail during a long haul. Another frequent headache is the security system locking you out, often due to degraded module memory in 2000 GMC Sierra pickups, causing no-start conditions tied to anti-theft protocols.

Replacing with this VIN-programmed BCM resolves these by refreshing the control logic, restoring proper signal relay to components. Take intermittent power door locks in a 1998 Oldsmobile Bravada; the issue might trace to voltage spikes damaging the original unit. Our module’s updated firmware prevents such vulnerabilities, ensuring stable performance. Dashboard warning lights, especially airbag indicators, frequently pop up from BCM communication errors—I’ve diagnosed this in Astro vans where a simple swap cleared the codes after recalibration.

For deeper insight, consider how age-related capacitor wear in these 1999-2000 modules causes random shutdowns. This fix not only eliminates symptoms but enhances overall system efficiency, potentially improving fuel economy by optimizing accessory power draw. If you’re asking, “Why does my 2000 Isuzu Hombre BCM cause brake light failures?” it’s likely internal relay degradation—our part counters that with robust, tested internals.

Easy Installation Guide

1. Provide your VIN immediately after purchase so we can program the BCM with the latest GM updates tailored to your vehicle.
2. Disconnect the battery to ensure safety and prevent electrical surges during the swap—locate the BCM in the center or left-hand dash area based on your model.
3. Remove the old module by unplugging connectors and unscrewing mounts; compare it to the new one for matching part numbers like 16257125.
4. Install the new BCM securely, reconnect all wiring, and reconnect the battery to power up the system.
5. Perform necessary relearns: If a no-start occurs post-install (indicating theft system activation), cycle the key from off to on three times, waiting 10 minutes each cycle for the security light to extinguish—per GM standards, this is only needed if issues arise.
6. Address post-replacement steps: Use a diagnostic tool for the ‘Setup SDM Primary Key in BCM’ to reset the airbag warning light, and recalibrate the brake pedal if your model requires it for safe braking performance—consult your manual or a tech if unsure.
