The Electronic Automatic Temperature Control on my 95 Town Car is bad, (or
so I believe.) A brief description of the trouble...
Last Summer I noticed that when I accelerated hard with the A/C on, the
airflow would switch from the panel vents to the floor and defroster. After
letting up on the gas, it would return. (vacuum problem? that was my
guess) Now the airflow is continuously at the defroster and the floor
(heater). Pressing the selector buttons for Automatic, or Max Ac, Norm Ac,
Vent, Floor, Floor&Def, and Defrost has no effect where the air flows. The
temperature settings do change the temp, and bring on the compressor when
needed. The fan speed wheel does control the fan speed. Fan also works OK
in Automatic setting, increasing in speed if you change the temp setting by
more than a few degrees, and then slowing after interior temp stabilizes at
So, basically, it works except for the ability to put the air where needed.
Since hot weather is almost here, it would be nice to have more efficient
A/C; especially for the people in the back seat. I have checked the vacuum
line from the engine to the back of the controller, and there is vacuum
there. Do not have any way to quantify how much, but regardless, it's
there. The vac lines do not appear to be leaking. I'm assuming something
or someTHINGS are bad within the body of the dash-mounted EATC
Questions- First, does anybody agree (or disagree) with my assessment?
Second, anyone know where to purchase new/rebuilt EATC at reasonable price;
OR get this unit rebuilt? [Last Winter I located online a source for a
new(?) EATC, but can't recall where. Remembering the price was between
$350-$400. Ouch!!!] Third, Anybody know how to diagnose that THIS is
really the problem or should I should take it to the Mercury dealer and pay
for a diagnosis.
Any and all suggestions appreciated. If you prefer to correspond directly,
you may reply directly to <gkasten AT brick DOT net>
Thanks in advance,
