The A/C started blowing ambient air, no cooling, and the A/C clutch was
cycling. The car has been converted to R134A. I got three cans of 11oz
refrigerant, plus stop leak and detector, and attempted to get it cooling
again. Got all three cans in after a long while, for a total of 33 oz. /2
lbs. However, the clutch is *still* cycling, but a little faster it seems.
No cooling. Don't have any specs on what the charge is supposed to be...but
I guess it wouldn't do any good to know that as I don't know how many ounces
were left in the system. There must have been quite a bit of refrigerant
left in the system, as it was showing about 85 on low side and 145 on the
high side before adding any. It is about 100/150 lbs (A/C set on max
cooling) after adding more. After I shut it down and the pressure
equalized, the static pressure was 128 lbs. At what pressure is the low
press. cutoff switch supposed to activate?
BTW, this is what was causing all of the dash warning lights to flash
on every 2 sec or so. You turn the A/C off, and the flashing dash light
problem goes away! Weird!
Yea I know you should change the receiver/dryer, evacuate the system
and put recommended factory charge in , etc. etc. Is my cutting corners
causing a problem?
