I just changed out the evaporator housing (due to a crack that was causing it to leak) and now I’m in the process of putting the dash back in and finding plugs that I am having trouble finding what they plug into.

I’ve alrea put back together. The two plugs are on the passenger side, between the CD Changer and the center console. I’m guessing that they plug into a blend door actuator and control the fan switching from the front defroster and the changing of the modes from face to feet for the HVAC. At present my A/C is only blowing in my face. There is also a black tube on the driver side that looks like a drain hose. I don’t know what it connects to either.
