[DML] A/C Question

["Dave Stragand" <dave.stragand@xxxxxxxxxxxxxxx>]

Hi All,
 
I hooked up the A/C on Project Vixen today, evacuated it, and charged it up.
 
I evac'ed the system for about 90 minutes, at 28" Hg, then charged it up.
The low side pressure is at 32, the high side at about 170-175, and the temp
today was about 75 F.
 
The system is blowing pretty cold (though not sure how cold, as I cannot
find my A/C thermometer anywhere) but the compressor isn't cycling -- it
just runs continuously.
 
Following the checklist in the workshop manual, it says to check for missing
expansion tube (it's in there, and it's new), or that the system is
overcharged.  Considering it only would take in about 28 ounces of R12, and
the service bulletin calls for 36 oz, I don't think it's overcharged.
 
(I do have one known small leak, on the Schrader valve on the low side hose
at the compressor.  I'm going to see if I can track down that nifty little
tool that allows you to change it without evacuating the A/C.  For now, I
have a plastic o-ringed sealing plug on it to help slow/stop the leak.)
 
I did have a problem where the back of the high-pressure cutoff switch came
off while I was mounting the high side hose, but it snapped back on without
a problem.  The compressor, accumulator, expansion tube and low-pressure
switch are all new.  Does anyone have any other suggestions as to why the
compressor will not shut off?
