1999 – 2000 GM BCM (BCM) 8162571250 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com
Remember that frustrating morning when your 1999 Chevy Silverado refused to unlock the doors, or the interior lights flickered like a bad horror movie? You’re not alone—I’ve seen countless truck owners pull into the shop with similar headaches, often tracing back to a faulty Body Control Module. Questions like “why is my 2000 GMC Sierra’s power windows not working” or “how to fix intermittent electrical issues in a 1999 Chevy Blazer” flood forums, pointing to BCM failures. This pre-programmed BCM, part number 8162571250 (compatible with 19153625, 8191536250, 16257125, 191583625, 8093668010, 8191536250, 09366801), arrives flashed with the latest GM updates using your VIN for a seamless match. It tackles those erratic behaviors head-on, restoring reliable control over body functions like lights, locks, and wipers. In my experience, swapping to a VIN-specific unit like this prevents compatibility glitches that plague generic parts, saving you diagnostic headaches and ensuring your ride runs smoothly on those long hauls.

Common Issues & How This Fixes Them
Dealing with a failing BCM in your 1999-2000 GM vehicle often shows up as mysterious electrical gremlins. For instance, power door locks might fail to respond, leaving you fumbling with keys in the rain—a common symptom when the module’s circuits degrade from moisture or age. Another red flag? Intermittent dashboard warnings or non-functional courtesy lights, caused by corrupted internal programming that disrupts communication with other systems. In trucks like the Sierra 1500, I’ve diagnosed cases where the wipers activate randomly due to voltage spikes overwhelming the BCM. This replacement unit resolves these by providing fresh, updated circuitry that restores stable signals. Beyond the basics, consider how heat buildup in the dash location accelerates failure; our pre-flashed module incorporates GM’s latest fixes to handle thermal stress better. Users searching “symptoms of bad BCM in 2000 Chevy Astro” often overlook related DTCs like U1000 for communication loss—scanning early can confirm the issue. By installing this, you eliminate root causes, preventing cascading problems like battery drain from constant relay chatter. One shop story: A client with a 1999 Isuzu Hombre had erratic horn operation; post-replacement, everything synced perfectly, avoiding a full wiring harness chase.
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—always a smart move for dash-mounted modules.
- Locate the BCM (typically center or left dash, depending on model like S10 or Sierra), remove mounting screws, and unplug connectors carefully to avoid pin damage.
- Install the new unit, reconnect everything securely, and reconnect the battery—double-check for firm fits to sidestep intermittent connections.
- After replacement, reset the airbag warning light by performing the ‘Setup SDM Primary Key in BCM’ procedure with a qualified diagnostic tool; some models may also need brake pedal recalibration for optimal safety—consult your manual or a pro if unsure.
- Test all functions like locks and lights; if issues persist, cycle the key for theft relearn as needed to fully integrate the module.
