Heater control cable in engine compartment

[CBODY67]

Aftermarket Mopar piece. Many times, the company Everco would provide aftermarket replacement water valves for the Fuselage cars which were metal rather than the OEM multi-color phenolic plastic. The "plastic" was perceived as such as the metal was perceived to be a better, long-term item. Either vacuum controls (as my '70 DH43N car has) or cable controls (as our '72 Newport Royal has).

So your 72 Newport has a similar piece as this one? Would you have a pic of how it's connected? Thx

That car still has the OEM valve on it. One difference is that the cable goes into a spring clip that is a friction-fit, which goes over the stud out of the valve, which opens and closes the valve.

On that car, the heater cable is a two-piece affair, rather than one piece as suspected. There is also an a/c compressor switch which turns off the compressor about 1/2 way to the full-hot position. The ONLY way to get the compressor turned off on a system that runs the compressor all of the time. As you move the lever from cold to full-hot, about half way, there is a slight click, after which the compressor is off. I can reposition the switch just past that click, but have the valve at full-cold. End result, the heater still gets hot enough being open only 1/2 way.

Just curious, if the compressor won't come on could that switch be the cause? Where is it located?

Could well be. Might be best to download a 1972 Chrysler Parts Manual and look at the hvac system controls, which details the heat cable location and parts associated with it. As I understand, the cable became a two-piece item. I suspect the switch is where the two cables attach.
