2000 GMC YUKON Body Control Module (BCM) 9377486 – Pre-Programmed to Your VIN with One-Year Warranty from Highway71AutoParts.com
Ever dealt with your 2000 GMC Yukon suddenly refusing to lock the doors or flickering interior lights that make night drives a hassle? As a seasoned mechanic who’s seen countless Yukons roll into the shop with erratic electrical gremlins, I know how frustrating it can be when the body control module starts failingโespecially during those harsh winter commutes where reliability matters most. Questions like “Why won’t my 2000 GMC Yukon BCM clear DTC codes for power accessories?” or “How to fix intermittent door lock issues in a 2000 Yukon?” often lead owners here. This pre-programmed BCM, part number 9377486 (also compatible with 16257155, 15136876, 09377486), arrives flashed with the latest GM updates tailored to your VIN, restoring seamless control over lights, locks, windows, and more. It tackles root causes like corroded circuits or software glitches, enhancing overall vehicle stability and even improving towing reliability by ensuring consistent power distribution to essential systems.

Common Issues & How This Fixes Them
In my two decades fixing GM trucks, I’ve pinpointed BCM failures as a top culprit for electrical woes in 2000 Yukons. One frequent problem is malfunctioning power door locksโcaused by degraded internal relays or moisture ingress from leaky seals, leading to security risks and daily annoyances. This replacement BCM restores responsive locking, often clearing related DTC codes like P1626 for theft deterrent systems. Another issue hits the interior lighting: dim or non-functional dome lights, typically from faulty dimmer controls within the module, which can compromise safety during low-visibility conditions. Installing this unit recalibrates those circuits, ensuring bright, reliable illumination. Don’t overlook erratic window operation; voltage spikes or software bugs in the original BCM might cause windows to stick or operate unevenly, especially in humid climates. Our pre-flashed module fixes this by stabilizing power flow, preventing further wear on motors. I’ve advised owners towing trailers that a failing BCM can disrupt trailer brake signals, risking accidentsโ this part improves towing reliability by maintaining consistent communication. Lastly, airbag warning lights may persist post-failure; the new BCM allows proper resets, enhancing occupant safety. Through real-shop scenarios, like a Yukon owner stranded with dead accessories after a rainstorm, I’ve seen how swapping to this BCM revives full functionality, often without needing extensive rewiring.
Easy Installation Guide
- Provide your VIN upon purchase so we can program the BCM with the latest GM updates before shipping.
- Disconnect the battery to ensure safety, then locate the BCM under the left-hand dash in your 2000 GMC Yukon.
- Remove the old unit by unplugging connectors and unbolting itโinspect for corrosion that might have caused the failure.
- Install the new BCM, reconnect all plugs securely, and reconnect the battery.
- Perform post-install steps: Use a diagnostic tool for the ‘Setup SDM Primary Key in BCM’ to reset the airbag warning light, and check if brake pedal recalibration is needed for optimal brakingโconsult your manual or a tech if unsure.
- Test all systems like locks, lights, and windows; if issues persist, cycle the key for theft relearn as needed.
