I have to ask - are you a pro? I was pretty good at recharging R-12 systems,
but R-134a systems are a whole different ball game. I tried once on my son's
'94 Acura, slowly charging and waiting for the cycling to settle down, the
pressures to get in the ballpark and the outlet temperature to drop, but
somehow I went right through proper charge without it ever working right.
All it needed was an evacuation and correct charge by weight to get it
going. If I understand right, the condensor doesn't cool down if you try to
do it the way I did; it just overheats.

Why does it need service this soon, and did you get the leak fixed?
