1999 – 2000 GM Various Models Body Control Module (BCM) 09366801 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com
Ever dealt with your 1999 GMC Sierra 1500’s doors refusing to lock while the interior lights flicker erratically, leaving you scratching your head in a dark parking lot? Or maybe you’re asking, “Why is my 2000 Chevy Silverado’s power windows acting up with no clear reason?” These frustrating symptoms often point to a failing Body Control Module (BCM), the unsung hero managing your truck’s electrical systems. As a seasoned mechanic who’s swapped out hundreds of these in GM pickups, I’ve seen how a faulty BCM can turn a reliable ride into a headache. The good news?

Common Issues & How This Fixes Them
In my two decades fixing GM trucks, BCM failures in 1999-2000 models like the Sierra 2500 or Silverado 1500 often stem from moisture intrusion or electrical surges, leading to erratic behavior. For instance, if your dashboard lights dim unexpectedly or the alarm triggers randomly, it’s likely the BCM struggling to relay signals properly. This can escalate to safety concerns, such as non-functional power locks during a roadside stop. Another common headache: “My 2000 Chevy Astro’s wipers won’t turn off—what gives?” That’s typically a BCM communication breakdown with the wiper motor relay, caused by internal corrosion over years of use.
Replacing with our VIN-specific BCM resolves these by restoring precise control over body functions. Take a scenario from my shop: A customer with a 1999 Isuzu Hombre reported intermittent horn failures, traced to BCM relay issues. Post-replacement, everything synced flawlessly, preventing potential accidents. For airbag systems, a faulty module might keep the warning light on, signaling a deeper fault—our unit, when properly set up, clears this by enabling the SDM primary key procedure. Brake-related glitches? Some vehicles need pedal recalibration to maintain ABS efficiency, ensuring safe stops on highways. Through detailed analysis, I’ve found that addressing these early avoids cascading problems like battery drain from constant short circuits. This BCM not only fixes the symptoms but enhances longevity, drawing on GM’s robust standards for dependable performance.
Easy Installation Guide
- Provide your VIN immediately after purchase so we can program the BCM with the latest GM updates tailored to your exact vehicle.
- Disconnect the battery to ensure safety and prevent electrical shorts during the swap—always a must in my garage routines.
- Locate the BCM (typically under the center dash or left-hand dash in models like the 2000 GMC Safari) and unplug the old unit carefully, noting connector orientations.
- Install the new BCM securely, reconnect all harnesses, and reattach the battery—double-check for loose wires to avoid post-install glitches.
- After installation, use a diagnostic tool for the ‘Setup SDM Primary Key in BCM’ to reset any airbag warning lights, ensuring safety systems are active.
- For some vehicles, perform brake pedal recalibration by following your manual’s steps or consulting a pro—this optimizes braking response and prevents uneven wear.
