2001 Base Impala, 3.4 Liter, Stock.

Single climate control. Need location for blend door?

It will not fully switch between modes. I.E. The floor and vent has air blowing out of both with the switch set to vent only, the defroster and vent has air coming out at the same time with the switch set on defrost only.

you most likely just need the actuator, and you can get to that under the center of the dash
