SOS Connection air conditioning W115

Hello everyone.
I'm fighting with the W115 220 gasoline and air conditioning. when I bought the car, I got it with the potentiometer of control air conditioning disconect. The car rides a York compressor. Well I have two afternoons tangling and get nothing, I mean. The W115 have inside the car , in the center air outlet have a rotary switch three-speed ventilation, this works very well, the same rotary switch also has the option to lock it or unlock it, pulling or pressing it. The latter is not so, then does nothing.

Below, over the radio the first potentiometer on the left is the command of the air conditioning If I turn all to the left, I hear as air inlet caps move, since that command will go three vacuum tubes, but that command also has two male faston connectors, which are disconnected, and not to wires going to it. The green lamp which is just on your right, also have two wires without connection. In the radio slot, I've located a cable with +12 v dc with contact, and if I connect it to ground , electromagnetic sounds - york compressor clutch. and put off and you hear very well that acts or goes OFF. There is some wire plus one green, one gray, finally, I have no outline and not as connecting the control of air, to test whether I work or not the air.
This is a gasoline W115 Series 1 220 , from november 1971.
Thank you a lot. and sorry for my bad english.

The rotary switch changes the ventilation over from heat to A/C and vice versa.

In addition to the vacuum switchover, the control has a temperature probe that fits in the evaporator housing.

When the control switches over from heat mode, it actuates vacuum air divert flaps, changes power to the A/C blower, and actuates the compressor.
