Is your 2002 Trailblazer, Envoy, or Bravada blowing hot air on one side and cold on the other?

Or maybe you hear a clicking noise behind the dash.

That's usually the blend door actuator going bad.

This is a direct replacement, part number 604-105, which also crosses to 52489426 and 89018525.

It controls the temperature and mode doors in your HVAC system.

Swapping it out will get your AC and heat working right again.
It's a brand new unit with a 1-year warranty.
