Where is the temp blend door acuator located on a 2000 chevy blazer?

The blend door actuator on a 2000 Chevy Blazer is located behind the dashboard, on the passenger side. Accessing it requires removing parts of the dashboard. It's usually near the heater core and connected to the HVAC system's blend door. There's no single easy-to-see location; you'll need to consult a repair manual or online video specific to the 2000 Chevy Blazer to determine the precise location and the disassembly process needed to reach it. A Haynes or Chilton manual would be very helpful.
