jrichker, Thanks for the above information, this is the next project I am looking at tackling on mine.
I do have a question, and hope this isn't a thread hijack. I noticed on the diagram, there is an outside recirculate door. On my car, I have some rust inside the cowl, which causes water to pour into the passenger floor when it rains real heavy. Right now I have the cowl temporarily sealed off, as this is beyond my repair abilities. Would it be possible to close the recirculate door and when I install the new A/C system, just run it with the door closed, pulling air from inside the car? Just want to see if it can be done before I purchase the A/C parts that the previous owner decided to remove.
