Dusty, I do not understand the comment "I have a hole in diagram in servo"??? I will just say that the shop manual and Cadillac Tim Groves 64 Comfort Control Diagnostics Manual are the two items you need to go through and diagnose the system. Almost all illustrations from the shop manual can be accessed from our Help page under AC/Heat. If you look through those illustrations you will have what I have and what is in the shop manual but not all the text and diagnostics, nor all the great info in Tim Grove's book. If serious about getting your system right, have both manuals handy.

Hey Jason, Thank you for the help and info! I'm going to see what I can do about swapping the motors for a little while, while I rebuild my 429
And finish up 63's engine bay and firewall. I guess I'm still doing everything ass backwards :)
Frank, if your 1964 is a Coupe DeVille (body style 6357, VIN 64J......), in addition to the items Russ mentioned (shift quadrant display, front driveshaft, gear shift linkage, etc) you will have different cross-member yaw mounts, neutral safety switch, and you need to make sure the 390 engine/trans setup includes the TV Rod, starter, trans inspection covers, rear trans mount, etc, as all of that is different between the Hydrmatic and Turbo Hydramatic Transmissions.
Is the heater hose "hot" on the heater core side of the water control valve? If it is, it is letting hot water to the heater core and will need to diagnose further. If not, you have issue at the water control valve. In heat mode you should have no vacuum at the water control valve diaphragm nipple leaving the valve open so hot water can flow through. In AC mode, Vacuum forces the diaphragm to close the valve. From there I would check the diagnostics in the shop manual and Tim Groves Comfort Control Diagnostics manual.
A day late, but I saw a picture of MLK riding through Baltimore in a convertible and after a little research I found a different angle and saw that the car was a black '63 convertible so I had to…Continue

Purchased from a knowledgable part supplier with thorough hands-on knowledge of 63-64 Cadillac engines, who checked the part before sending it to me. The oil pump driven gearSee S bore and the pressure relief piston bore are both .002 over and within the .005…
Good morning! I am Matias Adrogue. I bought a 1964 Cadillac coupe de ville last year and am real close to the final restoration details! I call her “Jaws 64”. Pics will be posted soon. I need advise regarding a AC/heater. It came stock in the vehicle but it does not work. A mechanic gave me a bid of $1700 to replace and repair. I am ready to install a new system - Vintage Air or Old Air Products from Fort Worth Texas. I would greatly appreciate your thoughts. I read the great write…
