On a 2004 Chevy TrailBlazer, the body control module (BCM) can be found beneath the dashboard on the driver's side closer to the middle of the vehicle. Responsible for managing functions like power windows, power mirrors, air conditioning, immobilizer system, and central locking, a malfunctioning BCM can trigger error and warning lights on the dashboard. These lights might flicker if the BCM is having trouble reading sensors correctly, impacting the vehicle's performance as it interacts with other control modules. If the BCM struggles to communicate with other components, you might encounter issues such as the car not starting. It's crucial to pay attention to these indicators, act promptly, and seek help. Ignoring or delaying addressing these signals could lead to further damage or a complete system failure.

These two morons are completely off-base. The Body Control Module (BCM) is situated under the back seat on the left side for the driver. Ignore what Andrew S. or Tina S. have to say, as they have no idea what they're talking about. Just your typical clueless individuals on the internet.

I own a 2004 Trailblazer and I'm wondering why the dashboard information display isn't working, yet the radio still plays. Additionally, the vehicle won't start and the gear shifter is stuck in place.
