Contact forum member Greyhounds_AMX He reproduces the cables for many AMC models.

If any one needs some extra parts, they are sure welcome to them once if finish getting one of the valves to work.

I’d take the valve out and bench test it to make sure it is working correctly mechanicllay. I think the thermostat is there to provide some degree of fine tuning to temperature - so if you fix the position and it gets too warm it will compensate and close the valve a little bit.

When replacing the cable it makes sense to cleaner up the heater box by where the cable exits the firewall. It is a hard bend there and that usualaly where it rubs and breaks. I am thinking you will probably have to take part of the dash apart again to swap it out unfortunately.

It will probably be next week before I can get a cable made up for you as I’ll have to dig out my supplies and nos reference cable.

Ok, thanks guys. 

Ian, I'll take you up on your cable offer if it's not too much trouble for you. I can see what you mean about being mechanical as well as thermostatically controlled. I see that the lever opens it at least part of the way and I'm guessing the thermostat opens it fully?  In any case, the cable's sheath is broken, so that will need to be replaced.  Let me know the cost and I can PayPal it if that works for you.

Will I have to take the dash apart (again!!) to get to the control end of the cable?   That would figure, as I just had the dash pad off last week. Taking it off is easy. Getting all the screws to line up when putting it back on is a PITA.

The rubber washer appears to be OK, as when the valve is closed I am unable to blow air through it.

They are completely interchangeable. You may examine the 72 as you clean it, and replace parts that are questionable with the 71 as a donar. Or use what you have from the 72.

Guys, I have two of these valves. One is from a 71' and the other is from a 72'.
The 71' valve is in good shape but is missing the plunger and locking tab. 
The 72' is pretty crusty looking, but still works.
Is it possible to take the one from the 72' and install it in the 71'?
Or should i try to clean up the 72"
And can someone explain the function of the thermostat?
Thanks, Tom

This one is from the 71'



This next one is from 1972.
