Can you identify this a/c system from attached photos? No insignia on the dash control. I have a minor problem and would like to get a manual or talk to tech support.

Obviously it is an older R-12 system. The back of the control panel may have a hint. Let us know what kind of troubles you are having, the fundamentals of AC systems are universal.

Heater hose control valve should close in a/c mode. It is a vacuum operatied valve. The valve closes when I disconnect and plug the vacuum line at the valve and the a/c works great. It appears there should be an electrical signal from the temp lever on the dash control panel, to a vacuum actuator. There are no vacuum lines to the dash control panel. Should be fairly simple to trouble shoot if I had a schematic.
