If that's not hooked up, your AC won't work. I can't remember exactly how it works.

I don't think NAPA will have that, but I could be wrong.

It controls the Vents also.. mine is screwed up somewhere, the only ones that work are the Winshield and Feet, and the ones in the sides of the Doors. The others haven't worked since I have bought the car. It's some kind of default setting..
