r134a proper recharge pressure
Okay here'* a wierd one for you all:
My A/C was not woring properly: the compressor was working (line heading into the firewall was nice and cold, full of condensate), but the air coming out of the vents was only about 5 degrees cooler than ambient.
So I checked the refrigerant pressure while the ac was on full blast: 40psi... right in the 'blue' zone of the gauge, indicating proper refrigerant level, right?. I verified it with a friend'* gauge and got the same result. It ain't the gauge.
Finally I just added more refrigerant, all the way up to 60 psi, near the 'red zone' and guess what.... now it works like a charm. Ice cold air.
What is going on here?
Your thoughts are appreciated,
