Blend doors

[Hard way]

Hey I’m going to replace the entire dash in my 99 two door. Decided to replace the heater core and blend doors while I’m in there. Question:
How many blend doors are there?

There are three dampers in the main box, one at the heater core and one at the blower for recirculation. RockAuto sells the GM ones. The heater and recirc actuators would be worth taking a look at as replacement is really tedious with the dash in.

You can quickly snowball into an evaporator and full a/c replacement if you get this far into it. Taking the box completely out (along with the evaporator) makes it easy to get everything sorted out.

Good copy. Thanks. Looking at a complete AC redo as well so this definitely makes sense
