The cars behind you back away in a hurry when the air conditioner lets go on the highway. Very dramatic.

Dear Charlie,

            This may be pertinent to your question.   I had twenty years of
AC malfunction finally diagnosed correctly and rectified by Frank Jerome in
DFW.  With the new Sanden compressor and R134 the system would malfunction
after a full charge in a variable amount of time due to a covert bad high
resistence electrical connection to the condenser fan that greatly impeded
fan function and therefore condenser function and efficiency.   I am sure
that due to that nefarious combination, I ran high AC system pressures that
would then peak in a silent, non-explosive, and expensive cloud of white
R134 gas billowing out of the engine bay and readily visible in the rear
view window.   Based on multiple episodes of this before it was found and
repaired, I am confident that you will not suffer a Hollywood-style dramatic
explosion of your AC system.   Just be aware that if you see the white cloud
in your rear view mirror, which may last for 1-2 minutes, you can maintain
speed, but be prepared to drive with the windows wide open.......  :-)

                      Warmest regards, Chuck Engles

Hi all

 

In the 20+ years that I've had my Pantera, the air conditioning has only
worked for a few sporadic months. It works fine when charged, but we can't
find the source of the leak, despite having changed nearly everything that
could be changed. So the system was charged again a few weeks ago preparing
for my trip to Le Mans Classic, and this guy did find a crimp that looked
suspicious, so we'll see how long I have cool air. 

 

Anyway, I seem to remember that we all know that at higher speeds (85mph+)
there is a low pressure area behind the AC condenser, which is why some
people move them up front. I also seem to remember something about the
system pressure getting too high because of inadequate cooling, and this
high pressure causing the system to explode. Is this correct? Is there a
risk from leaving the AC on full speed, non-stop for hours on end of high
speed highway cruising with the stock condenser set-up?

 

Thank you!
