73 autotemp question

["Woolf,Richard" <richard.woolf@xxxxxxxxxxxx>]

Jack,
 My '73 heater works like yours. No matter what the temperature is set on
you always get heat. My AC doesn't blow any cold air, and like yours it's
the servo unit which I was told you can't get anymore. I see you had yours
rebuilt. Could you send me their phone number.
Thanks

The 73 system is somewhat different than the 74-78 system but on the latter,
the temp lockout switch is an integral part of the hot water shut off valve.
If the 73 unit is anything like the latter unit in this respect, I would not
be surprised to see these two symptoms appear as you have described.  I
would first turn my attention to this valve and see if all is well there.
If the 73 ATC is way different than the 74-78 unit, then I would be way off
base.

Hi All!
   ok,  I've been through the FSM on this one, but am hoping for some
experience from the 'field'

I replaced the servo a couple of months ago with a rebuilt unit from the
Performance a/c guys in TN.

everything was fine until recently....

First,  the temp lockout quit working(would blow cold air on a cold morning)
but all else worked.
Then,  it just blows hot, no matter the temp setting.
  It does send the air to the floor or the windshield, depending on the
button pushed, and the fan speed seems to respond to either the normal or
'high' selection.

but,

heat only,  even when it's not needed.


funny how one thing is fixed  (shocks) and another couple crop up..
hah
  (I also have a rear window motor that stripped gears...)



Thanks in advance for the feedback..
