Engine Size: 1.3
Refrigerant Type: R12
Pressure Low: 0
Pressure High: 0
The system is R12 and completely original, except the cooling fan. It has functioned flawlessly for the last 4 years. Then the fuse blew on my cooling fan. Wife was driving and didn't notice temps rising and the sound/feel of the A/C loading up until it was too late (note to self: it is not the Wifes fault, it is NOT the Wifes fault, it is not the Wifes fault...).
The system was close to zero pressure when she got it back to me. I assume the pressure release valve vomited my 28oz of R12 into the environment. I added just enough gas to bring pressure up, used my sniffer to check around and didn't find any leaks. So I charged about 1/3 of the charge. The system worked right, clutch cycling a little to quickly due to the low charge. I sniffed it again. Since I didn't find any leaks, I charged till the glass was *nearly* clear. Center vent temps on high recirc hit 39*. I drove the car around a little, then parked it for the night.
Next day, system was empty (5 psi at 80*) again.
Should the pressure release valve reset? Is the pressure release valve leaking? I cannot sniff anything there. (mac tools sniffer works pretty well) Is it possible that the compressor shaft seal has 'blown'? I can't sniff anything around there either.
Never mind. I found a 'leak' in the center of the plug on the receiver/dryer. Looks like this is a pressure relief device. Can it be replaced or do I need a new dryer?
Some reset, others don't, if the new drier comes with the pressure relief valve, change it, if not you may need to change the pressure relief valve to be safe...
Freedoms just another word for nothing left to lose
Thanks Chick for the quick reply-
looks like it doesn't reset, it is some kind of fuseable material, probably melts at 200* or so.
