First I’d like to thank those who contributed to my understanding
of this problem. Between John Hudson’s excellent picture of the
vacuum lines (allowing me to isolated directly to the source
visually) and Gregory Andrachuk’s exceedingly helpful vacuum line
diagram, coupled with the help of several other seasoned veterans,
the seemingly impossible task of locating the loose line on the
servo switch has been accomplished.
At first, I thought I had done more damage than good, based on my
initial observation. Evidently, the climate control wouldn’t allow
me to initiate any settings except the defroster. It was almost as
if the entire system lacked vacuum (which evidently allows the
servos to actuate the defroster vents, but nothing else. Also odd,
was the fact that even the compressor only turned on while in the
defrost setting…very depressing.
Then, after what seemed like nearly 2-5 minutes of run time, I had
turned the system off and on a couple of times, the system suddenly
came to life on the ‘‘low’’ setting. It was as if all of the servos
had ‘‘awakened’’. All of a sudden, the center vent linkage was put
into action, the heater valve switch actuated, the compressor
kicked in, and frosty cold air poured out of the center and fascia
vents (in addition to the floor and rear vents). The AC was now
working perfectly, through ALL of the prescribed vents. I moved
the control to ‘‘high’’ and a blizzard of cold air shot through all
of the vents. I’ve yet to take her out on the road pursuant to
this ‘‘procedure’’ (I pretty much removed every interior dash/console
panel imaginable in my search and still need to reassemble),
however, I’m now hopeful.
I’ll let everyone know how things come out on her first road test,
which may be in a day or two, but this has been a REAL breakthrough.
Now for the obvious question…why did the system take a few
minutes to ‘‘come to life’’? Was it due to the absence of system
vacuum (normally maintained in a reservoir) and the need to
reestablish it? This is the only ‘‘logical’’ conclusion I can draw.
Unless, in my attempts to re-run the vacuum line I bumped something
(tons of connections near the bottom of the servo switch with which
I could’ve made intermittent contact). Any thoughts?
