Cadillac Tim has written and produced these incredible Comfort and Climate Control troubleshooting manuals. These manuals are detailed, and easy to understand. With these manuals the only tools you need are a vacuum guage, voltmeter, and small hand tools to troubleshoot these systems, whereas factory shop manuals require special tools that most of us don't have.

These manuals are year specific except for 1969-70 and 1972-73, which are combined. Each manual tells you how the system works, how to test each part, and how to troubleshoot the system. The manual also shows you how to repair the rotary valves, and how to calibrate certain parts.

It is very difficult to find someone today who understands these 40 year old systems, so these manuals will help you and your mechanic. For only $45 each they will also save you lots of time and money in repairing these systems.

The basic A/C and heating components (compressor, condensor, stv valve, etc) aren't covered since they are the same as the other GM cars of these years. The Cadillac-specific Comfort and Climate Control components are what is covered. Vacuum and electrical diagrams are included.

With over 200 of these manuals sold to date, we're sure you'll be satisfied. There truly is no other manuals like them!
