The cut for the service mark on the heater box of a 2000 Bravada is typically located on the passenger side of the vehicle, near the firewall. You may find it near the area where the heater core connects to the box. It's often marked with a label or a notch to indicate where to access the internal components for servicing. Always refer to the vehicle's service manual for specific details and diagrams.
