[DeTomaso] DeTomaso] Fwd: gauges that fog during use

[pantdino at aol.com]

Another thought-- I hadn't really paid attention, but I do think the 
gauges fog more during the winter.  My hypothesis is that the air in 
the center console gets hot because it sits above the coolant tubes and 
is heated by the electrical wiring behind the gauges.  The glass is 
cooler than that air, even with the windows open and no A/C on, so it 
gets condensation.  My ammeter used to get quite hot and fog up until I 
took it out of the system by bolting the two cable ends together.

So if that's correct the cure would be to seal the gauges and /or 
insulate them from the heat in the console.

My car lived the first 16years of its life in Kentucky, which does see
some humidity
The last 20 years have been in Los Angeles, which sees almost none.
My car's heater core is shut out of the cooling system with auxiliary
valves on both lines to it for 10-15 yrs and I have never seen any
moisture anywhere in the car.

 So I don't think the fogging implies any problems really.

I find it hard to believe that any automotive gauge is built literally
air-tight. This means that over time the gauge interior will assume the
temperature and humidity of he ambient atmosphere. When a car lives in
a hot and
humid area I'm not surprised if when you start driving the car and turn
on the
AC fog will appear on the glass. Do people in dry areas see less of
this?

Tomas, living in a generally cold and wet area...

 There is probably no individual
in the
Pantera community  as  knowledgeable  and experienced with Pantera
electronics
as Jon.

problem.
My problem and many others are from high humidity. This does not
necessarily
indicate that there is a coolant leak in the passenger compartment.

bulb
wattage /or high humidity
 would cause any condensation.
