This is what the indoor unit looks like installed. If I was a betting person I would think that this unit is a universal unit. The only difference would be the duct connection are probably glued on for the different applications. So lets make this work for what I want it to do. I am not going to use the defrost for the dash, so there goes two ducts. The two connections for the dash are in line with the console and pass side defusers so that is where they are going.
You see the two bolts in the back...They are not being used for the Corvettes but probably for another application, hence universal indoor unit.
Luckily the end cap is screwed on. I only need the upper connection, the bottom will be cut off and capped.
This is the door for the dash and the floor duct, it modulates between both.
Looking inside the unit you can see the heating coil on the left side and the door on the right in front of the cooling coil. On the drawings they call it a temperature blend door. That little dial that reads Temp on your control is what makes this move. What is does is when the temp sensed matches the set point it open the coil on the opposite side to mix the hot/cold air with ambient air. Hence mixed (Blend) air.
This is what I was talking about coiling the wire, you can actually induce/restrict volt in another circuit.
Lets start the mod. Unused connections cut off, this will be replacing the other ones for the dash since those are smaller.
This is the motor. It looks like a stack of checkers. If I didn't know better I would say they are two motors, 1 is CW and the other CCW.
The one question that I need to ask the manufacture is how to disable the two motors in the board circuit. Most new A/C units go through a self diagnostic check at start up to check all the inputs and outputs. There should be a set of dip switches that I can access to turn these two outputs off so the unit doesn't try to access or check for them.
