OK.  Back to ATC II...

So it's my understanding that I need to... ... install a heat valve on one of the
heater hoses to control the heat? and hook a cable from the temp slider
to the heat valve, correct?


Correct.  And I found the correct valve:

I really wanted one of these with the CD but I have yet to see one for less than $150.  I'm too cheep.




 

That's a steal at that price. I had on of those back when I had my Neon, swapped it out for the 5 band EQ/cassette with CD changer controls, and had the original radio for a few years until I pitched it

I went ot to the junkyard where i've been scavaging a '74 New Yorker on occaision.  I went there to pull the heater box so I could examine it on the bench just to see what is involved in converting to manual AC.

After 1/2 an hour, I gave up.  Ain't no way it's gonna come out without total (and I do mean TOTAL) dismantling of the dash.  I dread the day if mine ever has to come out.

More shtuff:

While studying the tech manual for AT II, I discovered that  if you convert to a manual AC setup, the temperature control cable HAS to go to the air blend door in the hater box and not the heater valve.
The heater valve has to remain vacuum operated.

The more I read, the more I.....

I don't see why it would have to remain vacuum operated, but it's just as well I suppose. You could have a vacuum valve that shuts the heat off with the a/c on, and then opens again when you want hot air. Then the air door would control the amount of heat just like a stock setup I suppose? Many cars didn't even have heater valves anyways, though I guess with A/C the hot water going though the heater core ALL  the time would waste some the cold air coming off the evaporator...

Here is non AT control unit for my '73, looks like the temp slider is for a vacuum set up as well? not sure what that switch is for though.

I've worked on cars for years, but never messed with this kind of stuff...never had a need to until I had an Auto temp car.

I think Mopar wanted some warm air in there to keep the evaporator from icing up

So I bought a NOS '73 non ATC temp control set up...Now I gotta figure out how to hook it up. I'm gonna pull the dash apart in a few weeks and start figuring out what vacuum lines do what. Can't say I'm looking forward to it.

I just got my replacement servo for the 73 Imp from ebay ($22.95 best offer + 10 bucks UPS! what a deal!) and disassembled it. It has a small crack in the housing caused by the mounting screws rusting, but most of the internals look OK. There was a bunch of antifreeze corrosion in the lower end that I cleaned out using mag wheel acid cleaner. I cleaned the middle section with Ultra One to remove rust without hurting the plastic.
Then I stumbled across this site...8 pages but it's an intimate look at repairing a servo (my unit was off a Mercedes so I trolled the Mercedes sites for info...)
