Hummer Body Control Module Replacement
The body control module in your Hummer manages electrical accessories including interior and exterior lights, power windows, door locks, wipers, keyless entry, and the security system. When the BCM fails, you'll notice symptoms like flickering lights, unresponsive power windows, or keyless entry that stops working.
