The concepts for 1966 are the same. I also recommend Cadillac Tim's book available at www.cadillactim.com It helped me fix the AC in my 1966 and I'm not at mechanic at all. If I can do it, anyone can do it.
I am constantly leaning something new about my car everyday. And I've had her almost 15 years, since 09/06/2005. I never knew the vents were suppose to face up, what a difference it makes ! Love ! Love ! Love ! this Video !
2:47 Cadillac obviously did NOT hire a “hand model” (yes, a real profession) to photograph this. Look at that nasty, dirty mechanic’s fingernail! Yecchh.
I have never cared for this type of thing. I prefer to adjust the temperature, fan speed and mode of operation myself. Unfortunately today, this is the only thing that you can buy unless you purchase a low end vehicle.
I can sympathize. I like the automatic temp piece, but warm *only* comes out at feet, and cold *only* comes out of dash vents. Fortunately, one can add switches to override it and discreetly hide them in an ash tray.
