1999 – 2000 GM Vehicles 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 1999-2000 GMC Sierra or Chevrolet Silverado, leaving you puzzled during a long haul? Or perhaps you’re asking, “Why won’t my truck’s power windows respond in my 2000 Chevy Astro?” These frustrations often trace back to a failing Body Control Module (BCM), the central hub managing everything from interior lights to door locks. Our pre-programmed BCM, featuring part number 9366801 and compatible with alternatives like 19153625, 16257125, and 09366801, arrives ready for your specific vehicle once you supply your VIN. This ensures seamless integration with the latest GM updates, restoring reliable performance without the guesswork. Drawing from over two decades in auto diagnostics, I’ve seen how a precise BCM swap can transform intermittent electrical glitches into smooth operation, preventing roadside headaches and boosting overall vehicle safety.

Common Issues & How This Fixes Them
In my years fixing GM vehicles, BCM problems in 1999-2000 models often show up as non-responsive power accessories—think doors that won’t lock or windows stuck midway. This stems from internal circuit degradation, exacerbated by moisture or voltage spikes, leading to error codes like U1000 for communication loss. Another frequent headache? Intermittent no-start conditions, where the BCM fails to relay signals to the theft deterrent system, stranding you at the worst times. I’ve diagnosed this in Silverado 2500 Pickups, where heat buildup under the dash accelerates wear. Our pre-programmed BCM resolves these by restoring accurate signal processing, with fresh GM updates that address factory vulnerabilities. For instance, in a 2000 GMC Safari, replacing the BCM cleared persistent interior light malfunctions, as it recalibrates the network for flawless operation. Don’t overlook airbag warning lights post-install; a quick diagnostic reset can prevent safety risks. Through real shop scenarios, like a Blazer S10 with flickering gauges, this module proves its worth by providing a plug-and-play solution that outlasts makeshift repairs.
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 surges during the swap—always a smart move for dash-mounted units.
- Locate the BCM (typically center or left dash in models like the 1999 Silverado 1500) and remove the old unit by unplugging connectors carefully.
- Install the new BCM, reconnecting all harnesses securely to avoid loose connections that could trigger faults.
- Reconnect the battery and perform any necessary relearns: If no-start occurs, initiate theft deterrent relearn by cycling the key from off to run (without starting) for 10 minutes, three times.
- Test all functions, such as lights and locks, to confirm full operation before hitting the road.
