GMC Sierra 2500 HD high beam headlights stuck on and requires daily jump start due to back ordered parts on GMC Sierra 2500 HD

Some GMC Sierra 2500 HD owners report experiencing issues with high beam headlights that remain stuck on, even when the truck is turned off, which may indicate a deeper electrical problem. These owners have noted that corroded headlight components can lead to extreme dimming in low beam headlights and may cause intermittent functionality or eventual failure. Additionally, issues with the low beam relay and high beam relay controlled by the Body Control Module (BCM) could be contributing to the problem. A faulty headlight relay or malfunctioning body module may also be responsible for the high beams staying on. With parts back-ordered, it is essential for owners to address these electrical issues to prevent battery drainage and the need for daily jump starts. Seeking assistance from a certified mechanic or GMC dealership is recommended to diagnose and resolve the underlying problems. In the interim, some owners resort to disconnecting the battery when not in use, manually turning off the high beams by removing fuses, or exploring alternative parts sources for quicker availability. It is crucial to resolve the root cause of the high beam issue to ensure the safe operation of the vehicle.
