well, first off the compressor was not coming on, o i thought the refrigerant level was "low" enough to need a little charge so the pressure switch would activate the clutch.
so i hook up my el-cheapo hose/gauge and can of 134A....
after a minute the compressor clutch kicks in and the gauge comes up to the "green" charge indicator....
but, there is still only hot air coming out of my vents....so i bite the bullet and take it to my local shop that i trust.
well, my shop guy hooks up his unit and recovers from the system to a 30 pound vacuum, and then shuts it off to see if it will hold the vacuum.
after it holds the vacuum for a while he starts to charge the system.... well once it is charged enough we start up the engine and the low side jumps up to the 100-120 psi range and the high side is in the same ballpark ( basically equalized )
now my shop guy seems puzzled and is honest in saying that he just normally charges vehicles but never does much on the "hard" side of A/C ( like replacing the compressors et al ) hence why i like the place ( honesty when you are not sure and say you aren't goes a long way in my book )
so, is this a case of a bad compressor, which i would put on myself and have him charge back up, or something else entirely?
sorry for the long post, just wanted to put out as much info on this as i can
thanx for the help in advance, John
