I know that the 69 system is fused & not on a breaker, so
something else is going on here. Sometime in 73 when I had my first 69, the
resistor burned out & the shop wired the system so it would work till they
could get another resistor for it. They taped the temp dial in the lowest
position & warned my not to touch it. Even with it taped, hitting
bumps would often blow the fuse.Even that new, it took quite a while to get the
part from Chrysler.

Subject: IML: AutoTemp I (1968)
My work on the 1968 Imperial Crown convertible has gotten to
the point where I am testing the AutoTemp. The AutoTemp has an interesting
problem.
I believe that the system was working correctly when
I bought the car, and was still working correctly when I first
re-started the AutoTemp today.
However, the servo began to make a
grinding sound, while I noticed that the system would not start
on "Auto" but would start on "Hi-Auto", "Def", and "Hi-Def". After the
system is on, pressing "Auto" turns it off.
Pressing "Off" causes a
buzzing sound, which I think is the circuit breaker, and cuts the fan
abrubtly and leaves the A/C doors open.
I cannot hear the servo
trying to park.
My bet is that corrosion has gummed the servo
works, causing the motor therein to jam, and thus trip the breaker. Does
this sound reasonable to those of you who have worked on this
system?
I'd like to open the servo box. Does anyone here
have experience with this style servo? I'm curious to know how similar
or disimilar it is to AutoTemp II.
Thank you for your
insights!
