There are fresh air inlets on the fronts of the rear fenders. A thermostatic control varied the amount of outside air entering the system. In very humid and hot conditions the outside ducts would be automatically closed. And the inside air would be recirculated , increasing cooling efficiency. The ad that Erik posted is indeed a 1955 ad for Buick AC. But, the ad is not quite correct, for the '55 AC jobs; The outlet registers shown in the ceiling were last used in 1954. Buick mechanics found that disconnecting the clear plexiglass ducts from the ceiling duct work increased the efficiency of the AC unit. So, for 1955, the Engineers eliminated the ceiling registers, letting the cooled air come into the cabin directly from the plexiglass ducts.
Pretty sure I saw this car at the Moultrie swap meet in ga last weekend. I also saw another complete restored car with this system installed and working. Was very neat and cool!
Mine is not an AC job. And, I have yet to see an AC job outside of photos. My understanding is that, there are blend doors beyond the manual flapper. The engineers may have deleted the automatic feature as they did the ceiling registers ---------- Post added at 07:35 AM ---------- Previous post was at 07:33 AM ---------- [/COLOR] Cason, I would like to see a working system. I would like to see a system period!
