Re: IML: 68 LeBaron update

Ken,

First of all, I must congratulate you on scoring that beautiful LeBaron.
It's rare to find *any* almost 40 YO car in the hands of the orignal owner.
And to think you got a 68 LeBaron in that beautiful color combo.  And loaded
with all those choice options.  The find of a lifetime, I'd say.

As far as the autotemp system, I've banged my head against the wall
(actually the bottom of the dash) many times trying to fix that system in my
70 LeBaron.

During my last attempt I discovered that the quarter-sized vacuum check
valves located on the underside of the heater core/evaporator case (just
above the front seat passenger's toes) were defective on my car.

The valve has an inner chamber that is capped with a plastic plug and that
plug causes the inner chamber wall to split.  The vacuum leak prevents the
autotemp system from turning on.

Look to those check valves sooner than later.

The Auto Temp system is completely dead right now.  I'm reading through the
manual to get familiar with the operation so I can get in there and fix it.
The good news it that the compressor and refrigerant are in tact and
working.  I tested that by jumping the compressor clutch coil to 12 volts
while the engine was running.  The compressor ran smooth and the low side
refrigerant lines got ice cold.  So my first assumption a problem with the
control system.
