Alfetta Air Conditioning Pressure Switch Leaking

[Leslie Wong <lesliewong@domain.elided>]

Now that it is warming up somewhere in the world, I decided to
try to use one of the Interdynamics charging kits to try to get
my converted R-134A (York F206R compressor) system working in my
'79 Sprint Veloce. It was working a few months ago. I thought the
refrigerant was low because jumping the switch on top of the
compressor switched it on.

I was successful for about two minutes. The compressor switched
on after recharging and when I measured the pressure with kit's
gauge it was OK. Then I noticed my investment in R-134A was
leaking out of the low pressure cut off switch near where the
terminals come out of the plastic.

On my Alfetta CD, I see the part illustrated on page 88 of the
parts manual corresponds to Alfa part number 10548.10101.00.

I looked at the ccicompressor.com site and found a compressor
service manual but I think this switch is not really part of the
compressor valves and fittings.

I would appreciate any help. Does anyone think this part is
available anywhere? Do you think I could repair it with JB Weld
if I cleaned the switch thoroughly? Would a professional AC shop
have this switch? Or should I just use what my girl friend calls
Alfa Romeo air conditioning - opening the vent windows so they
point at driver and passenger.

Thanks
