64 AC theory and practice

[David Lee]

my 64 Deville is early and I believe a 5 port A Module

I'm seeking guidance on the following

If in restoring the AC climate Control - What are the components other than the module that need to be 

changed other than the module itself and the first vacuum hose that attaches to the module?

Dave, You will want a 1964 Cadillac Shop Manual and Tim Groves 1964 Cadillac Troubleshooting Manual as you go through the 64 AC/Heat Comfort Control system.

You can get shop manuals on eBay and elsewhere in original print, reprint, and CD/PDF file formats. I usually have extras to sell but other than one coming apart at the seams I am out ... so check eBay.

Here is Tim Groves' contact info:

David, the 64 climate control system is the first year design, and a challenge to repair.  I do carry the troubleshooting book by Tim Groves. The book  is 45.00 plus shipping.

There is a circuit board in the climate control head that will probably need to be repaired, a power servo that will most likely need to be repaired. 

If you want my advise, just replace the entire system with a 63 Cadillac system. It bolts right into place and will heat and cool the car just fine with a whole lot less of a headache.
