I am going to install a factory a/c in a 260z to replace the after market unit that's in there at the moment and I have a couple of questions. Why is so much controling of the airflow flaps done by vacuum? (The air intake flap, the air distribution flap, the water valve), is this an effective system? does this mean that the flaps will be opening and closing depending on how hard I put the foot down, I would have thought that there is a great potential for problems in this setup and the old fashioned cable and flaps would give a more reliable control.
Thanks for any help
