This is my third go ahead with the a/c system on the explorer, the vehicle is a 97 sport, 4.0 ohv. To make a long story short the first time I refilled it was when I bought the vehicle, culprit turned out to be a bad low pressure switch, the second time I had to refill b/c of a blown compressor, and now the third time I'm refilling b/c of a bad compressor (again, that's what you get for buying used parts I guess). I followed glacier's write up, I was able to get about 27-28 mm Hg of vacuum and the vacuum held for 6 hours so I assumed no leaks and proceeded to start charging. I was able to get an entire can in through the high side without the motor running. Shut the high side off, turn the motor on, put the can upright in some warm water and open the low side. About a half can went in (so total maybe 20 oz in the system) before I started seeing the high side pressure shooting to the moon, it got up to 350 before I shut everything down. The system has evened out at about 110 psi on both the high and low side gauges. I replaced the orfice tube when I replaced the compressor so I'm pretty sure that's not the problem. Anyone have any ideas?
