Summer has arrived in Texas! As if on que, my A/C performace was dropped off a great deal, and that's putting it mildly. I was wondering, just how low does the R12 have to be before the "low" warning appears on the CRT? I've searched the shop manual, but did not see the information stated. I'm assuming that the R12 is indeed low. On "Max Cool" the outlet temp is 79 deg. There is no longer any water dripping out of the evaporator case and the compressor, while it does engage, does not cycle as it has in the past. Both the radiator fan and condensing fan are turning on. I've owned the car since August of 98 and have never had the R12 checked. What's odd, in the winter when the temp is between 60-50 degrees sometimes the "low warning" does appear. However, a number of other forum members have reported the same problem when it's cold. Currently, there are no warnings on the CRT for any Climate issue. Everything reads OK. Any thoughts?
Along that same vain, I have a set of A/C guages, but I don't know which ports to connect them to. Can anyone tell me. I would like to know what the pressures really are.
